Router problem with 5ghz

Question: Router problem with 5ghz

Hello, let me explain my situation.
We live in an apartment complex and there are 3 desktops that connect to the router. On an evening we were experiencing extreme lag which we determined was due to traffic on the channels.
We bought a router that can use 5ghz and also 3 new compatible adaptors. Installed it, worked just fine on 5ghz.... for a day. Then the signal took a dump and ping was between 700 and thousands on all pcs.
Rebooted the router after reading forums and seeing this as a common issue until reboot, and it was fine again. Signal took a dive again a day later, rebooted again. This time only 2 of the pcs were getting the speed, and the other one was barely getting any (no more than 1gb/s). Rebooted, that PC was fine, the other 2 were under 1gb/s. Rebooted, and they all switched order again. Finally got all 3 working, again just for a day until the signal took a dump, now I cant get more than 1 PC (the same one this time every reboot) at max speed.
Switched them onto the 2.4ghz, works fine. Back to 5ghz, nope nothing, clinging to connection for its life on 2 of the 3 PCs.

All 3 are using identicle adapters, 15 feet from router no walls, and are set up identicle. Channel is on auto as is the frequency (have tried 20mhz, 40mhz, and a variety of channels).

Does anyone have any idea? Thank you

My question is I have a computer with 2.4ghz as well as 5ghz, my router is a dual band 2.4 and 5ghz wireless n and no matter what I do my computer will not recognize the 5ghz network.

Background info: I have read through many forums and tried many different solutions none of which seem to work. My computer is 2 weeks old (hp). I have gone into device manager and clicked on the network card, properties, and advanced tab to discover my computer does support both 5ghz and 2.4ghz, as well both are enabled. My router is the wrt601n linksys dual band N wireless router. I have tried every setting possible with that router including : mixed, n only, a only, 20 or 40 all different widths and no matter what combination my computer will only pick up the 2.4ghz. Both drivers/software for my computer and router are up to date with the lastest. I have also tried close to and far away, distance and range are not issues either. It's becoming a major issue not having both bands working because we having gaming equiptment that when somebody is playing it kicks the other person off of the internet entirely! I am at a loss here on what to do please help!!!

Answer:Computer won't recognize 5ghz router (computer has 5ghz), windows 7

Go into your cards'
'Computer management' > 'Device Manager' > right click on your wireless card > 'properties' menu > 'advanced'

Check that 2.4/5ghz is set up for your correct country band! (UK = 1-13)

To turn on Dual band wireless 'n'
My linksys 2.4/5 pci card has a menu item called "Multimedia Gaming environment" > 'enable'

This enables dual band - top speed @ 300!

Back in January I posted this. Since that post, I've bought another Wireless-N card (a Linksys WMP600N) and saw no improvement in speed or signal strength. I thought the router was at fault, but having been turned off by my disappointment in my new card, I asked my cousin to bring over his ASUS RT-N16 (with ddwrt installed). The results were the same as with my Netgear WNR2000 even after lots of tweaking, so no increase in speed at all *. So my question is, would I find an improvement in speed if I opted for a dual-band router? All I want is to get my download speeds that I get wired (which is about 24mbps down and 4mbps up, the upload I get already). If I were to opt for dual-band is there one I could find that's selectable dual-band for $60 or even simultaneous? Is getting a dual-band router a wise choice or am I doomed to slow 7mbps download forever over wi-fi?

*N-only devices were connected. I have no G devices on my network.

Answer:Should I opt for a 5GHz router?

Get a router that can do both - enable 5GHz for everything and test it out. If it doesn't work well or is limited because of materials in your house, switch back to 2.4GHz. IF it does work well, enable 2.4GHz as a protected 'guest' network for when your buddies come over. Most decent routers these days have dual radios and some even have two discreet sets of antennae so implementing the above suggestion has no downside.

WNDR3700 all the way.

It seems like the only 5GHz routers available nowadays are dual band, which is fine if that is what it must be. But all I am looking for is a good 5GHz router that will be operating at 802.11a, not N.

It needs to have good range too.

So far I was looking at this one.

Also, will I lose a lot of range when compared to 802.11g? Right now the wireless G router being used is

Answer:Decent 5GHz router?

What is "good" range?

To me that could be 100ft in circular-diameter and to you it could be 1,000ft.

I mean it's like going into an Auto Dealership and saying "I need good mileage."

Ok, well is that 15 Mpg or 30Mpg?

I have a router on one side of my house that is broadcasting 2.4GHz. I have an extender on the other side of the house that is connected to the router with 2.4GHz, but it is broadcasting 5GHz. Both the router and the extender have the same SSID and password. Is this a suitable setup if I want to roam the house on the same network?

Thanks for the help!

Until recently I used the 2.4GHZ band for my pc and my son used 5GHZ for his laptop on our D-link router.
A couple of weeks ago our provider installed a new Cisco modem/router-in-one (the old modem didn't work any more). We use the D-link as a second router. The 2.5Ghz band is no problem but my son doesn't get internet access with 5Ghz although if I log into the router I don't see anything wrong. Any help would be welcome.

Answer:No internet access on 5Ghz band with Dlink router

can we see an xirrus screen shot - the d-link is still broadcasting both signals
Run Xirrus Wi-Fi Inspector
Download and install
If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and install the program.
You will now need to take a screen shot and copy that back to the working PC and attach the screen shot in a reply on the forum here.
Direct link to the program is here

{If the above link does not work heres another link,77196-order,4/download.html}

Then run and install the program - on a wireless enabled PC/Laptop
if you get an error - You need will need to have NET Framework installed for the WiFi Inspector to function.
On windows 8 - (i do not have windows 8) but, it would appear that, When you first try to run, you may get a message that .net framework is needed, and included in that message is a link to download/install.

Run the program

For example,

i have both the 5ghz and 2.4ghz SSID & passwords the same.

When I'm in 5ghz range my file transfer speed is awesome. However when I go outside to my backyard 5ghz gets really weak so my macbook auto switches to the 2.4ghz radio, but here's the problem.

When I come back inside my Mac never picks up the 5ghz radio again. it just stays on the 2.4ghz mode.

I recently got the newest NETGEAR router device, the NETGEAR Nighthawk X8 AC5300 Smart WiFi Router, and I am unable to connect to the 5GHz WiFi it provides on its Tri-band WiFi. I am currently only on its 2.4GHz WIFI, which I assume is lesser than the 5G. I am able to connect to the 5GHz on my smart phone, so I know it exists from the router. I am running a windows 8.1 currently on a desktop on an HP Envy 700-213 Desktop PC.

Edit: My computer supports 802.11b, 802.11g, and 802.11n radio types - which supports 5GHz WiFi
My adapter is a Ralink RT3290 802.11bgn Wi-Fi Adapter

Any ideas for why I am unable to connect to this WiFi?

Answer:Unable to connect to 5GHz Wifi on NETGEAR Tri-Band Router

The most likely explanation is that the wifi adapter in your HP Envy 700-213 doesn't support the 5Ghz band.

If you really want to connect at 5Ghz you will need to get a new wifi adapter for your computer.

I'm trying to connect my Lenovo B40-30 AIO to a D-LINK 816 A/C Wireless Router which is a dual band router (2.4GHz and 5 GHz). B4030 is able to connect to the router at 2.4 Ghz, however it does not detect 5GHz connection at all. I've updated the Qualcomm Atheros AR956x Wireless Network Adapter with latest driver from support site. However it still does not detect the 5GHz network. Leveno B40-30 product specification mentions capability to connect to 802.11a/c networks. So what else needs to be done?  

Answer:Lenovo B40-30 Windows 10 does not detect 102a/c wireless router at 5Ghz

hi kishor_shinde,
Welcome to the Forums.
From this AIO B40-30 specs sheet, this unit can be configured with a b/g/n or an AC wireless card.
Seing that you have the Qualcomm Atheros AR956x Wireless Network Adapter (WB335 a.k.a QCA9565), this Wi-Fi card supports b/g/n only which may explain why you're only able to connect to 2.4Ghz Wi-Fi access point and not 5Ghz.
From page 51 of the B40-30 hardware maintenance manual, you will need the following card to connect to 5Ghz:

If you specifically ordered a B40-30 with an 802.11AC card then I recommend you contact the place of purchase as you definitely received a wrong model (and also to see if it's still possible to exchange the unit)

Hi everyone, I have a Linksys AE6000 Wireless USB adapter in my Laptop and it is 5Ghz enabled. When I first got my laptop it had Windows 8 on it, but before I did anything I reformatted it to Windows 7. Under Windows 7, this wireless adapter connected to my 5Ghz SSID on my router (the 2.4 and 5Ghz SSIDs are different from one another on my router) just fine and I was getting 500Mb/s speed over Wi-Fi. Then, I upgraded laptop to Windows 8.1, where adapter only detects my 2.4Ghz SSID, and now I only get 150Mb/s over Wi-Fi.

What do I do? I have tried reinstalling driver, using Win7 compatibility mode drivers, installing manually without GUI, I have made sure internal card is fully disabled, etc etc...

My specs are as follows:

Intel Core(TM) i7-3632QM Quad-core mobile CPU
Intel HD Graphics 4000
AMD Radeon 7670M GPU 2GB
Samsung Evo 120GB SSD
HP ENVY/Pavilion m6
Internal Wi-Fi card - Intel Wireless-N 2230
External USB Wi-Fi - Linksys AE6000
Router - Netgear R6300
Internet Connection - 150Mb/s down , 10 Mb/s up

Hi, I have a netgear WNDR3400 100nar router, dual band, 2.4ghz and 5ghz. I set up 2 connections. On the 2.4ghz I set up a WEP connection with 64 bit encryption for my wireless repeater (WNR2000). On the 5ghz i set up WPA2 for regular use. Unfortunately my computer does not support 5ghz or atleast i dont think it does. My samsung tv picks up the 5ghz so I connected to that, the macbook pro connects to the 5ghz. The other computer I want on the 2.4 ghz with the repeater. Hardlined via ethernet anything and everything works. For some reason 2.4ghz wont connect wirelessly and does not even give me the option to enter the hex key. just says unable to connect. the 2.4 doesn't work on anything (currently the repeater is offline until I can fix this issue). Infact, ignore the repeater info. I think there is a problem with the distribution of the IP addresses. Could they be overlapping between the 2.4 and the 5? The next item on the network (tv) using 5ghz, occupies sequence 2 under the ip address....whatever the default is it would occupy I have reformatted my computer, uninstalled and reinstalled network drivers, as much as I could do with the computer itself so I'm assuming it is the router. I've disconnected it and reconnected it, reset it, redone the whole network multiple times, renewed the IP address. What is going on? Can anyone help me please.

I thought I had a double NAT problem, online somewhere it said go into Bridge Mode, CSR said the ISP router is already in that mode.

I have a cable router as my ISP, hooked up to a ASUS router (2.4GHz and 5GHz) for the house. Have 10 devices on the ASUS. On the Cisco ISP router, I got my Desktop computer in port 2 running to my Ethernet port on the back of my computer, and ASUS in port 1 which goes to the blue input port on the ASUS. I turned off the WiFi on the Cisco router.

The question I have is how can I log into my ASUS router when hard-wired into port 2 on the CISCO router.
CISCO is - ASUS is using port one, Computer is using port two
ASUS is - Can only access this router when connected to it via WiFi.

Especially if I'm not near the router as it then automatically shifts to 2.4GHz due to better signal. The issue is present with any network - not just my home network.

I was trying to make my sister-in-law's wireless connection secure (they've had wireless set up for awhile unsecured), and all seemed to go well until magically, it didn't. It allowed me to set up a password -WPA2/Personal, it was fine, other devices (ipod Touch and another laptop) connected to the network by putting in the right key. HOWEVER, the original laptop, now wants no part of connecting to this network. It finds the network, but doesn't even let me get to a stage at which I need to enter the WPA key.

Answer:Wireless router problem - laptop finds router, refuses to connect

That IPCONFIG shows a direct connection to a broadband modem. If that's when you're connected to the router, something is amiss.

I know there is a buttload of bad stuff on my computer, but I need a quick fix for my problem now.

My router/modem work fine. They're connected to my computer and VOIP, and they work perfectly. The problem is the internet does not register this and thus doesn't work on other PCs. In other words, I can't get my laptop to recognize my router.

When I start up network connections, I get this message:

runtime error
program: program files\microsoft broadband\msbnutil.exe

this application has requested the runtime to terminate it in an unusual way.
Please contact the application's support team for more information

The original message was "broadband error" or somethign like that so I did a week old system restore. No good. So I figure there's a problem on my computer.

Also, I tested the connection thoroughly, and I reset them, and junk, but still I got nothing.

Hi all,

I am using a Netgear Cable/DSL Web Safe Router Gateway RP614v2 with a Motorola Cable Modem SB4200 Surfboard Cable Modem for my Internet connection to OptusNet broadband. They works fine with my Desktop and notebook.

As I want to go for wireless with my notebook, so I buy the Netgear Wireless Router BGR614v5. However, I find the the new wireless cannot talk to the Motorola Cable Modem. Even I directly connect the Cable Modem with my notebook, the Internet connection is not through. It seems that the Cable Modem only allow the old wired router to go through it.

Is it any setting stored in cable modelm to allow the old router only to go thru, not other router or eveny my notebook. I heard something about MAC address. I check the settings in my current wired router, the option choosen for MAC address is "Default MAC". Does it cause the problem?

What should I do to remove the limitation to allow my notebook and my new wireless router to connect to the cable modem?

Thanks in advance,
Opal Chung

My home network use to consist of 3 comps all running XP Pro and a Vonage router. With the addition of a 4th comp, I have had to use a port on the back of the RTP 300 for one comp. The four others ( 3 comps and the Vonage router )are connected to my Linksys WRT54GL. and I have no problems sharing files and printers. The one comp connected to the Vonage router will not allow file sharing or show up in Network Connections although it has no trouble accessing the net. Is there a setting in the Linksys router that I have to change to allow this one comp to share? I can't access the RTP 300 to make changes as it is locked.

Dear forum,

I have a certain situation for you:
6 people use LAN-cables connected to the same router in the basement. They all have decent internet.
One day, the 6th person decides to connect a (wireless) router on his end.
Ever since then, the other 5 tenants have had very slow internet connection.

They're pretty sure it's due to the last person installing his wireless router. However, they have no idea how to explain to him how exactly his router is causing the troubles.

How would u explain what is causing the slow connection? (does it have something to do with 'ethernet' and 'gigabit ethernet' ?) ( you can throw whatever terms u want at me, I'll google them if necessary.)

Thank you,

Answer:home networking problem: router - router

Did he just plug his router into the other router, and then expect everything to work properly? If so, that's a really bad idea, since DHCP is likely enabled on both routers, and the IP conflicts between them will definitely be part of the general mess. If you can provide the make and models of both routers, then a walk-through on here might be possible.

Just moved into a new apartment and my Belkin router isn't cutting it to get wireless to the other end of the apartment. Looked via my phone and it seems 2.4 ghz is oversaturated in my building, so looking to go 5ghz. I was thinking it'd be easier to just add a new WAP than an entire new router, but I'm open to suggestions. Hoping to keep the price around $100.


Answer:Looking for a 5ghz WAP

I don't know how you're going to connect these devices but if you're going to use cable the TL-WDR3600 or TL-WDR4300 can easily be converted into an AP using OpenWRT, they are however bulkier.

Question: 2.4Ghz or 5Ghz?

I apologize if this question has already been asked a million times. I just set up a Dlink DIR-825 in our new house and I'm trying to decide which frequency to use for our laptops. I used a wifi strength meter to survey the house and it seems that the 5ghz band gets about 10% less signal throughout the house. I read that the 5ghz isn't as good at going through objects/walls as the 2.4ghz is due to the wavelength. I also read about interference on the 2,4ghz band due to cordless phones, microwaves etc...

Long story short, am I better using the 2.4ghz range for our laptops since it has the better range? I could use the 5ghz if I needed it for saying streaming hd movies or something like that.


Answer:2.4Ghz or 5Ghz?

Did your wifi strength meter tell you what strength you've got?

Consider this,
2.4ghz w/ excellent signal & lots of noise from other devices or
5ghz with/ good signal & low noise from other devices

With less re-transmitted packets & interference you may see better performance from the 5ghz.

I have been doing a lot of reading about wireless networks. Here is my main question: Is there a substantial performance advantage to running 802.11n in the 5Ghz spectrum?

The reduced range 5Ghz offers will not effect me because I live in a small NY apartment. I have very thick solid walls, one line of signal strength is the most I can pick up from anyone's network, so the extra "uncongested" bandwidth offered by the 5Ghz spectrum isn't really a factor. I thought that 5Ghz 802.11n was supposed to offer twice the speed of 2.4Ghz 802.11n. In all the reviews I have been reading it seems like there is little or no speed advantage.

I have a Wii which connects via 802.11g so I can either go with a straight single radio 2.4Ghz router like the D-Link DIR-655 or a dual band/simultaneous 2.4Ghz and 5Ghz router like the Linksys WRT600N. I transfer large HD video files (between 4 and 10GB) over the network to my PS3 so speed is important.

My laptop has an Intel a/b/g/n wireless card. In the reviews I've been reading they try and pair up a router with the same brand wireless card. Is that an indicator that my Intel card is not going to get the same throughput as in the reviews? Can someone clear up my confusion please?

My lovely ISP has decided to swap out all the costumers old normal modems for these new modem/router hybrids...basically a modem with router capability. I got the TC7200 Technicolor model. I use the 5Ghz Wifi on it for my newer network devices ie: Ipad, etc etc, but the signal on this TC7200 is horrid, so I was thinking of upgrading my access point which is a D-Link Dir-655 (2.4 mode only ) to a newer dualband 5Ghz capable one. Now my question is, will the access point work with the 5Ghz just like it does with the 2.4 now? The way I have it set up is Coaxial->Hybrid TC7200 ( with 5ghz wifi turned on, 2.4ghz turned off) -> access point with 2.4ghz turned on. Sadly the old Dir-655 only does 2.4 and I want to boost my 5Ghz around the house (Yes I know, the 5Ghz isn't as good when it comes to reach as 2.4 for now, but that's another story. Anywho, would this work? Would the access point accept the 5ghz wifi range since my TC7200 Modem/Router hybrid does? The Tc7200 runs on its own SSID, different than the AP, and if I were to get a 5Ghz wifi AP, I would simply turn off the TC7200 Wifi due to poor signal quality. I have drawn a simple diagram of the wifi / wired setup as is now. I am willing to spend around 100-150 Euros on a good solid dualband router *AP*. I am also trying to get my ISP to switch out this damn Technicolor TC7200 for a Cisco epc3925 ..but that's another story for another thread. I know how just have to get lucky with a good rep from their company.

Answer:Question about using 5Ghz AP

The deal is with 5Ghz it will not go through walls worth a damn, so it's not something you can cover an entire house with. A 5Ghz A/P will cover a very large room or outdoor space really well but just won't go through walls or floors. The reviews at Newegg reflect this in a most unpleasant manner.

I'm running the DIR-655 as my main router and DHCP server then I'm also running the Asus AC66U as an access point, it's mounted outside my house under the eve. I've tested both bands and routers extensively. The 2.4Ghz signal on the Asus is much stronger than the DIR-655 which is still a very good router, but the 5Ghz signal on the Asus seems only good for large rooms or large outdoor areas without obstacles which is where I'm using it.

Of course it does give me 1.1Gb wireless speeds 35 feet away on the 5Ghz band but this is only true because it's an open area outdoors with a straight shot to the antennas on my Asus AC66 PCI-e NIC which is installed on my garage machine.

Any more questions?

I like to show off this wireless speed from the Asus AC66U.

Ok, I have Optimum Online and my internet speeds have been horrible since I don't know when. Playing regular games on my PC with my brother playing xbox games online at the same time can make lag for us both if it is being really slow, and usually me going on youtube while he plays makes him lag. Youtube videos load slow, I get slow download speeds online, and speed tests show slow results. But, during the night my connection is super fast, and the speed tests show correct results. I know this has to do with everyone being in bed and no one being on their internet, so there's alot of bandwith available from the ISP. My dad is almost certain it is OOL, but I think otherwise. We have had our modem replaced 3 times now, and we have had the same router forever. My wireless is a whole different story, so I won't go into that that much, but it is slow, as well. My router is a Netgear RP614v2. I have been trying everything to see if this was the problem, and I just installed a newer firmware after googling a bug with the router. I believe it was only a reporting error, and it didn't help my situation much. Basically what I want to know is should I be in the market for a new router, or is it probably not the problem? I know I didn't really provide that much information, but just tell me anything else you need to know and I'll get right back to you.

Answer:Is it time to get a new router/is my router the problem?

first thing you need to do, is bypass the router and hook the computer directly to the modem and see if the same issues persist.

if you still get lag and slow speeds without the router in the picture, it's not the router.

To check if your S20-30 supports dual band, press the Windows key+R, type devmgmt.msc and press Enter. On the Device Manager, navigate to Network Adapters and check the wireless card that's installed. If you see an Wireless AC adapter then you should be able to connect to 5Ghz network.

Reposting from router recommendation thread due to lack of responses.

I just bought a WNDR3700 to upgrade my wireless network. I have two primary goals:

1. Get my one HTPC that is connected via wireless bridge (due to its location) out of the 2.4GHz band because of microwave interference; and

2. Move to 802.11n to increase bandwidth to handle additional wireless HTPCs.

Currently, I have my HTPC and Xbox 360 connected to a WRT54GL. The WRT54GL connects to my primary wireless router via bridge mode. I prefer to use a bridge instead of buying separate wireless adapters for the Xbox and HTPC. I'd appreciate any recommendations of wireless routers that I can use as a bridge to connect via 802.11n in the 5GHz range. DD-WRT compatibility is a big plus. Gigabit switched ports also a plus, but not that important.

I could just buy another WNDR3700, but I am looking for a less expensive option.

I thought that 5Ghz would always beat 2.4Ghz hands down on everything apart from distance. With this in mind I set my router to broadcast at 5Ghz and thought that my wifi would be much better as a result,but it wasn't.

I have my router and my PC in the same room a few meters from each other, and while I was using 2.4Ghz I would always get 90% signal strength,but when I changed to 5Ghz instead of my signal getting to 100% it went to 70%? My router is capable of both 2.4Ghz and 5Ghz so why is it that 2.4Ghz is better than 5Ghz when I have been told that it should be the other way around?

I was told that microwaves, cordless telephones and other electronic devices use the 2.4Ghz frequency range and this causes intereference and as such causes a loss of signal.

5Ghz I was told is free of other electronic noise so it is much better and you will always get a stronger signal. The one thing which I was told that made 2.4Ghz better than 5Ghz was the fact that legal restrictions on 5Ghz routers meant that the amount of power they could use to output a signal meant they were not so good over long distances, and in some countries it was even illegal to use 5Ghz frequency.

Answer:2.4Ghz vs 5Ghz puzzle?

The higher the frequency, the more power it takes to emit said frequency in comparison to lower frequencies. If you have a decent router, however, it shouldn't make a difference which band you transmit. Just because the router CAN use the 5GHz band doesn't mean it'll operate best on it.

It wasnt a screaming fast machine to begin with, but it ran it ok form office apps and web surfing.

issue:due to having internet that requires long in to connect i use connectify to use several devices. with other computers there is no issue but when i use my acer i have issues with devices not connecting. the internet i use seems to sometimes connect with 5ghz and other times connect 2.4  the issue is some devices do not support 5ghz. with my other computer i was able to go into device manager and change the wireless mode. i do not see that option on the acer though.question: so my question is does anyone know how to shut off 5ghz so it only connects using 2.4 ghz on a aspire v5 with a Qualcomm Atheros AR5BWB222 Wireless Network Adapter? thank you

Answer:can i turn off 5ghz on aspire v5

What's the part number of the system (first ten characters of the serial number only) and I'll look into this for you.

I have recently upgraded to a 150 mbps Wi-Fi plan, and have noticed that my laptop barely scratches 50. Apparently, this is due to the fact that my laptop uses, and can only use, the 2.4 GHz, despite both the laptop and the Wi-Fi stick supporting 802.11a/n. I'm guessing this is a problem with the OS now, but correct me if I'm wrong.

In reading the messages on this board, it appears I need to install an Intel Advanced-N 6205 to allow my E520 11433BU to access my 5 GHz wireless N router. So where can I purchase this adapter? From other source, it is recommend that this be purchased directly from Lenovo, but I can't find it on the web site.

Hei all, I am really not a PC person, so excuse me if this is stupid.  I was wondering if my Acer Aspire E1-571 supports 5GHz wireless internet? I have recently bought a new internet, which is 60mbps, and it has a dual band with 5GHz and 2.4GHz. I am able to find the 5GHz through my iPhone, but not on my laptop, so I have to connect to the 2.4GHz. So the problem with 2.4GHz is that it's completely terrible! I barely get like max 15mbps when doing a speed test... While the 5GHz shows full speed when doing a speed test from my iPhone.  So I am wondering if my laptop supports 5GHz, but it has just a problem that won't let me find the 5GHz wifi on the wifi list or it doesn't support it at all? If not, then is there a way to "make" it support it? Because then it would be really stupid to pay for 60mbps, when I can barely reach 15mbps (and at times only 2mbps) Here are some screenshots of the network info: This and This Thanks in advance!

Answer:Does my laptop support 5GHz?

Hi,Your WiFi card doesn't have the 5GHz support, you need to replace it with another card with dual band support, like Intel AC7260 or Intel 7260.

I got an RB751U-2Hn but I'm getting 30Mbit at most under ideal conditions. Nobody in my area is using Channel 11 and I have tweaked the TxPower and other settings to no avail. I don't know if 5GHz will help but I would like to try.

Anyone know of a dual band mimo AP in the $100 range?


Answer:recommend 2.4/5GHz MIMO AP

What brand and type of wireless card are you using in the client? 30 Mbit is about 3.8ish MB/s which is not abnormal for a computer connecting at 150 mbps on an N access point. It also depends on if the card itself can do MIMO. There's many factors here. What are the specs on that card and what speed is Windows and the router reporting that you are connecting at?

For all of you wondering about the new CPUs from Intel, looks like they're fro real. Here is an example of the 860 hitting 5Ghz! Looks like it's some real competition for the 920!

The Gigabyte P55-UD4P thread - Overclockers Forums

I have the same setup as this guy, although my cooling and RAM probably isn't as good. This is amazing!

Here is a well known benchmark site. Not much is beating the 860. (only 965 and 975)
You're getting quite a bit for the $$$$$ !!!!!!! Sweeeeeeeeeeeet

Answer:New Core i7 860 hitting 5Ghz

FYI - just took the i7 860 to 4.0Ghz with a slight bump in core voltage and RAM and the rest on "normal"

This may turn out to be a 920 killer. If you want to spend more $$ you can get better with the 965 or 975 but for 1/3 the price and almost the same guys thinking about upgrading the 1366 should start doing some reading.

This 1156 socket will do anything from $200(i5 750) budget gaming to extreme performance. (i7 860 or i7 870)

Until something else comes out, the i7 860 is the one to beat for price to performance.

4Ghz with almost no effort (stable with prime 95 for 2 hours)

I'm fairly unfamliar with the technology surrounding wireless networking and what not, but I recently upgraded my router to a wirless N ( linksys e2000 i believe) and I purchased a new wireless card not noticing that it doesnt operate at 5ghz but rather only at 2.4ghz. I tried looking on new egg and there seemed to only be 1 or 2 cards they sell that do operate at 5ghz. Is the technology not optimal at 5 ghz? I was going to return the card I ordered but I am not sure if I am just missing something. I know on my current card that I had for the G router, my speed is capped at 54 mbps and when I tried to new card that I am considering returning, it did go up to 65 mbps even on at 2.4ghz, bu the connection did seem to be less stable (a lot more lag spikes). Can anyone give me any feedback on this issue? Is there a better place to look for 5 ghz cards? Should I even bother?

Answer:5ghz wireless cards

802.11A runs in the 5 GHZ range.
802.11G runs in the 2.4 GHZ range. (and 802.11B, but who uses that anymore?)
802.11N can run in both 5 GHZ and 2.4 GHZ range.

Most 802.11N devices that can operate on 2.4 GHZ and 5 GHZ are advertized as "dual band" devices. If the device is smart, it can open up multiple spatial streams on each band to help insulate it from interference on the other bands, and acquire greater throughput.

If your wireless access point or router supports "dual band" operation, then investing in matching "dual band" wireless devices will probably give you a more reliable signal and better throughput on the network.

The only real disadvantage of the 5 GHZ range over the 2.4 GHZ range is that at higher frequencies radio waves loose signal faster over distance, so given the same broadcast power a 2.4 GHZ signal will travel further. In the realm of wireless networks, you probably won't notice any difference between the two tho.

Heres some background info:

linksys e3000 with latest tomato firmware
1 wired pc
1 wireless pc laptop 5ghz
1 wired mbp
1 mba wireless 5ghz
2 wireless iphones on 2.4ghz
1 apple tv wireless 5ghz
1 ipad mini wireless 5ghz

So my issue is regarding the apple tv and the ipad mini. They sometimes have an issue "remembering" or "reconnecting" to my router on the 5ghz. Sometimes it'll take several minutes before it connects to the wifi. On my macbook air (also on 5ghz) it connects instantly. I tried googling this but came out empty, search results were not similar. Any idea what this could be? Something with the router settings most likely?

I would like to connect 2 computers at a distance of ~8 meters with only a wall in between. Sustained real life performance should be 100+ Mbps. Obviously I cannot run an ethernet cable.

Now, a Linksys E4200 coupled with a 3 antenna adapter like the TEW-684UB should work like a champ but burning 220+ euros on an ad-hoc connection like that isn't optimal (I already have a 2.4ghz wireless ADSL router).

Is there another way to do this?

Answer:Fast 5Ghz Ad-hoc network

Any particular reason you can`t run a cable? Obviously, that`s the best, quickest and most simple solution but you`ve said you can`t run a cable, just wondering why that is?

Don`t think there`s a chance you`re going to see that sort of sustained throughput on that 2.4Ghz router. I don`t suppose there`s any chance it`s an N device is there? Even 150N, I don`t think you`d see sustained 100Mbs.

You do know you can go up to 100 metres on ethernet don`t you, so even if it wouldn`t be a direct 8m run, you could go up to 100 metres of cable (remembering to count any patching you may do).

Just a thought..

Question: Intel E3300 2.5ghz

I just bought and install a Intel e3300, very fast CPU. 2.5GHZ. I was curious if i was to OC the cpu to 2.8ghz would this damage anything ?

Answer:Intel E3300 2.5ghz

That's kind of like asking how long is a piece of string.

Theoretically, No...That would assume that you aren't raising Vcore to any great extent and you have adequate cooling.
Raising the clockspeed from 2.5 (800FSB) to 2.8 (900FSB) on a CPU that has a 12.5 multiplier shouldn't be much of a cause for concern, aside from the factors I've already listed, and of course whether you have a motherboard that allows overclocking.
Whether you would be gaining any tangible performance increase is probably just as relevant to ask...before you begin.

I've often wondered, that now CPUs are much more easily getting past the 5GHz mark, could there be any problems with them being too fast? Is there any limitation in computing, similar to the 3.8GB RAM limit, that could cause problems in the future as we get higher and higher clocks?

Just a random question :P


Answer:5GHz+, random question

I don't believe so because I think that the 'limitation' is inherent to the clock speed. I don't think there's any limitation (in terms of bit addressing like x86 vs x64 with ram) with the CPU speed as any limitation is of itself, not an external factor.

I have a cisco e4200 and after installing Windows 8 RP, I was unable to find the 5GHz band. I am getting 90Mbs on the 2.4 GHz band and I know my 5Ghz band can give me more. The 5 GHz band is detected on my PC before Windows 8 was installed but I can't find it on my PC now. I have two computers who support the 5 GHz band and both can't find it but did with Windows 7. The 2.4 GHz band and 5 GHz band are separately named so that isn't the problem. Can anyone help me?

Answer:No WiFi N 5GHz detected

This is most likely just a driver problem as most drivers have not been updated to support Windows 8.

Using the compatibility mode by right clicking before you install the driver might help.

If you want full wireless N speed of 300Mb/s then using the 802.11n Only mode in your routers settings with WPA2 security and AES encryption will get you there.

Both my router (BT Home Hub 4) and Wireless Card (N600 Wireless Dual Band PCI Express Adapter) are dual-band compatible but my computer will only connect to the 2.4GhZ speed. My PC is situated roughly 3 meters away from the router through 2 walls, I'm running Windows 7 and have all the updated drivers for the wireless card.
My housemates phone connects to the 5GhZ even when he's downstairs so I'm not sure what the issue is, at the start my computer would connect to the 5GhZ but it started to cut out and now it's stuck on 2.4GhZ.
Some help would be lovely, thanks!

Answer:PC Won't use 5GhZ wireless speed.

Same problem with Virginmedia.
Probably a new wireless card needed. My computer is only 15 months old and will not connect to 5ghz so have my router set to 2.4 and I am only about 2 ft away from the router.
laptop will not work on 5Ghz either but that is fairly old.
I have no problems with 2.4Ghz as it works ok.
The problem is ISP's when they give you a modern Router they are usually set to 5Ghz and 2.4ghz and they expect their customers to know what is wrong when their computers do not work.
Got fed up telling some to change to 2.4ghz but always got the same answer there is nothing wrong with my router. So left them to it.
