Preferred Solution: wireless rs232

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Question: USB - RS232

On my old pc i used a belkin ups with their bulldog software. The ups connected to the pc via a serial cable and all worked very well.So I buys a new pc and realise that it doesn't have a serial port. So I get a USB- RS232 cable (serial connector one end to connect to the ups and a USB conector the other end).I installed the drivers from the disk that came wit the usb/serail cable but the ups is not detected. Interestingly if I go into device manager, after installing the driver, and expand the tree so that i can see the driver one minute its there the next the device manager tree closes then opens and the driver disappears then it re-appears!My operating system is win xp home sp2.

Answer:USB - RS232

TomGI've used usb-serial converters, not all with the same degree of success. In most cases however, a reboot seemed to cure most ails, and sometimes only with the usb converter connected before boot up. Not a lot offer, but might be worth a try if you haven't already...

Question: Rs232

I am planning on building a small form factor PC but it will need RS232. I don't know for sure if there will be room for an add on card for the RS232. Is there a usb to RS232? If so, will it work as good as an add on card?


Usb to RS232 adapters/cables are common (on Ebay) and I assume they work well but I have never used one myself.

Question: RS232 on TV

RS232 on TV and Freeview Sat box. What is this serial port for?

Answer:RS232 on TV

Dunno about the TV. But my Humax Freeview STB has serial connection which can be used for uploading firmware upgrades from PC (after first downloading from Internet). Although the upgrades are available over the air, they are available sooner off the Internet.For this to work, one requires (for my box) what is known as a Null Modem Cable (and, of course, a serial connection on your PC). Cables avaialble on ebay, maplin etc.If you haven't got a serial connection on your PC, you can get a USB to serial adapter.It should all be described in your manual.Maybe the TV can take firmware upgrades in a similar way.

Hi allI am thinking of buying a new lap-top (nothing fancy) but I note that none seem to have an RS232 port any more.I MUST have RS232 because one use of the laptop would be in communicating with all sorts of strange devices that use RS232 (using all sorts of software).I know that USB to RS232 converters exist BUT now to the question:One piece of software I use is Hyperterminal and it "looks" for ports (eg RS232), but as far as I can tell, doesn't see USB (my son's laptop only has USB, and Hyperterminal only comes up with TCP, modem and COM4 (IIRC) which is the infra-red port). And all the other software (i.e. other than Hyperterminal) just seems to find COM1 and then works.Thus, does anyone know how all these RS232 bits of software could find the "port" via USB? Would the USB to RS232 converter cable have software that turns USB into COM1?Has anyone used stuff like Hyperterminal via USB?Thanks for any help.Skeletal

Question: RS232 problem

This is for the really old hands...

Got this Seiko labelprinter on Com4 (hispeed pci serial card).
My mobo is Asus P5Q3 wifi-ap deluxe.
I am always on a hell of a ride before I get this to work, these are the options shown in device mgr.:
bps 9600...115200 (several tried)
databits 8
parity none
stop bits 1
flow control none/hardware/xon-xoff (think hardware was the control of choice when it at at last worked for prior W7 installs: Beta, RC, W7)
Com 4

Msg "printer communication error".
Only possible setting on the printer is the com port.

Now I can try for days changing this and that and maybe as before it starts to work "just like that", but it is annoying: I had a crash and reinstalled W7 Ultimate.

W7 gives me a choice of two universal drivers, V8 and V10, tried to change to V8 but that doesn't change anything.


Answer:RS232 problem

Normally you don't need to change settings on the port itself. I would look towards a driver issue here (check for drivers for the printer itself that are comparable with W7)

Question: No RS232 support

First, I appologize for this being so long-----I have a laptop I was given to use at work that is dual booted into Windows 98 and XP Professional. The Windows 98 is being used for the DOS architecture only. It is not a full operating system setup. I use this DOS for operating a data acquisition machine. However, this new laptop does not have an RS232 port for the DB9 adapter cable that is on the data machine. What I am trying to do is to use a USB conversion cable as this laptop has many USB ports. I know I need a USB driver for this to work. I went to the adapter's webpage and downloaded the driver for Win98 (as there is no driver support for DOS). Here is my dilemna: being that Win98 is not a full operating system, the driver will not load. Is there some way I can manually place the driver in config.sys and autoexec.bat in the DOS architecture. I have tried many configurations that did not work. Unfortunately this data system has to run in DOS only.

Answer:No RS232 support

No.It would have to be a driver written specifically for DOS to work properly.

When i connect usb to port the wizard takes over and asks to install disc but then it will not install .
Have downloaded different drivers but it still wont work,drivers are on desktop i think
thought cable was not working so ordered another but same problem.
Am i doing something wrong?

Answer:usb to rs232 problem?

Some manufacturers of converters like this require you to install the driver software before connecting the converter to the computer. I would suggest going into device manager and uninstalling the converter, restart the computer. Hopefully on the driver disk there is a "setup" or "install" utility that can be executed, run this install and after it is done connect the converter to the USB port on the computer and let the New Hardware Wizard do its thing. If this doesn't fix the problem try a different vendors converter.

Hello,I've got a plotter (well, it's a vinyl cutter), which is serial and according to the manual the pin-outs are as follow.It looks to be as if they put '1' for RTS when really they meant '7'. However, that aside, is this a standard straight through cable because TX/RX are not crossed but I thought if it were straight through then 4/6 and 7/8 wouldn't be linked?I'd rather just buy a cable, but this layout is confusing me Thanks for any help in letting me know about this layout.

How do I determine if the USB port is actually getting data to/from the system's COM port?

Some info:
- I have Vista Home Premium
- I purchased a Generic USB to RS232 adapter (from China) based on a PL2303 chip.
- The driver that came with the adapter seems to have installed properly.
- I have RealTerm installed.
- I jumpered Tx to Rx plus other pins on the male DB9 connector.
- I sought help from Prolific (re PL2303), but found nothing helpful.

But I don't know how to look for data passing through the adapter. What I type on the keyboard does not show up on the RealTerm screen.
I've worked with RS232 for years, and know about the signal-type on the USB port.
But now I am stumped, and about to cut the vinyl covers of the adapter.

Question: RS232 vs. Parallel

While working on a larger problem I found I was not quite sure of the port and cableling names. Is DB-25 RS232 the same as a Parallel port? Also, What is RS422 and RS485.

I know that DB-9 is RS232 and a serial port, so I assume that DB-25 RS232 is simiar to a serial port but I think I may be getting it mixed up with a standard Parallel port as well.

I had found one site but it was too technical for what I need to know. I just want to know an example of it's purpose and what type of connecter they use.

If someone could straighten me out on all this it would help me a lot.

When I run the software associated with the scanner, a light on it flashes, but nothing else happens.Does anyone have any idea if I am using the combination of cables etc?

Answer:Rs232 to USB cable problem

If the port on the Laptop is an RS232 Serial port, are you sure it isn't 25-pin male? You should be able to get a 25-pin female to 9-pin male RS232 Serial Cable to connect the laptop and scanner directly. Have a look at this page click here

The UPS doesn't have to be connected to the PC via USB or serial to protect it so you can use it as is.

Buy it will likely work for management with a USB to Serial adapter, Windows 7 has built in support for many APC UPS's out of the box. You may also find newer APC software for your model on the APX website.

This controller connected to my PC through a serial port and could be easily programmed to change lights etc. Since the old PC died and I have bought a new one there is no serial socket on it.

I have a CyberPower USB to RS232 adapter. From the research I have done this should create a Com Port in my "Device Manager" so that programs
are then able to use it. I have researched this specific device and there are apparently problems with how it works on WIndows 8.1 but I have not been able to find a solution. The driver for the device was installed by WIndows plug-and-play controls. It decided
that the "HID-compliant vendor-defined device" driver version 6.3.9600.16384 was appropriate, however there is no Com Port in the "Device Manager" and instead a "USB Input Device" appears corresponding to the adapter each time
it is plugged in. Under the "Devices and Printers" the "Unspecified" device "CPS RS232 USB Bridge for UPS" shows up. 

When I attempt to use drivers from a different source (the manufacturer of the USB to RS232 adapter), the plug-and-play ignore the new drivers and use the ones from above.

How can I get the Com Port created so that I can use the adapter properly?

Is there a way to circumvent the plug-and-play and use the driver from the manufacturer?

Thank you for your help.

Answer:CPS RS232 USB Bridge for UPS - not creating Com Port

Regarding current situation, let?s try to manually install the driver by following these steps:

Device manager -> Right click the device and choose update driver -> Browser my computer for driver software -> Let me pick from a list of device driver? -> Have disk -> choose the driver manually to install.

Then let me know whether this device can work fine.

Hello All,

As a surveyor, I'm trying to slowly solve all the glitches on my new Windows 8.1 laptop.

1. Mouse

I often visit this NSW government site SIX Maps

When navigating the map, you use the mouse scroll wheel to zoom in or out and hold down the left mouse button to pan.

In my new windows 8.1 laptop, the scroll and pan functions won't work.

Iv'e tried 4 different mice and none of them work but they all work on my old XP laptop.

I've also tried 2 browsers (Chrome and IE)

I have also been in touch with the NSW goverment support team to no avail.

Looking in control panel, I couldn't recognise anything that would help.

Does anyone have any ideas?
2. USB to RS232 serial port cable replicator

This cable is used to download/upload information to the survey instrument. It worked fine on Windows XP, but will not work on Windows 8.1. It may be something to do with the port configuration.

Please note that the software is very old and I had to create a virtual XP machine using VMWARE to run it. (As well as some other obsolete software such as XTGOLD and Q.EXE! Any one remember these? I've yet to come across any file editing program to equal Q.EXE)

Hopefully someone will have some ideas otherwise I'll have to go back to the manufacturer and they'll charge more than I paid for the computer!!!

Thanks in advance for your help,


Answer:Problem with mouse and USB to RS232 cable

Well, I tried the link you provided and I was able to scroll using IE, Logitech Mouse, and Windows 8.1 Pro (64 bit). However, when I first accessed the site, it said that their site would work better with FireFox or Chrome. I have Chrome installed but did not try it.

USB to RS232, which end connects where? Does the USB end connect to the computer or the survey equipment? When running your XP, does it provide an error when you try to connect upload/download data? I would think that your VMWARE and XP will be able to handle everything, but you will need to play with port settings to have everything configured the way it was before. For example, my wife's computer is Windows 8.1 Pro, and I have her run VMWARE and Windows XP so she can use the embroidery module for her sewing machine. The one thing you have to do is to make sure that when you start the VM machine, you must tell the VM machine to use anything plugged into the USB ports to be used in the XP and not the Host machine.

Anyway, don't give up yet and keep poking around you'll find a solution.

I have a need for an RS232 port probably PCI, but I see such a wide diversity of prices. Which should I choose? Some have a UART and some do not. Do I need a UART? Thanks, Jim

P.S. I'll be using it with ham radio software called Ham Radio Deluxe (HRD) and a ham radio transceiver Yaesu FT-950

Answer:Adding an RS232 PCI port to my desktop

Check to see if you have a PCI slot. Some newer PC's only have PCIe slots and if they have a PCI slot it is a "bridged" slot to the PCIe bus and many PCI devices will not work or work properly on a bridged PCI slot.

I would check and see what others with that software are using.

(ex W5DVO/ZD8JES).

Since installing SP3 to my Windows XP Pro system my RS232 serial port no longer works. I have a Hyperpen tablet that has an RS232 connection so it no longer functions. Is there a converter that I can attach to the male RS232 so I can connect via a USB port? I have seen a USB 2.0 to RSB (male) serial adapter dongle but that is of no use. I'd appreciate any suggestions towards resolving this.

Answer:RS232 serial port not working

Have you checked in Device Manager to see if it is working there , or if there any conflicts . It won't have just broken , it must be a software problem as it occurred as you loaded SP3 , it might just need reconfiguring , what does the tablet need in terms of port speed etc. , data bits , flow control etc. ?

On a box running Server 2003 the application needs to talk out a serial port to an OPTO-22 I/O system. The Optoscan program from the manufacturer works just fine. Our application (which has been used many times before successfully) is not sending or receiving message. It appears that another application has grabbed the port.

We have a slitter scorer machine in which tools are placed via servo motors. Servo motor is controlled with servo drive and each servo drive is sent the values of a set of parameters to set a job. The main control system is DOS based which sends the values of parameters to all drives according to job. The data flowing is as MS DOS_RS232 port >>> RS232 to 485 converter >>> parallel connection to all servo Com ports. I want to monitor the data following from MS DOS to drives for which I have arranged another RS232 to 485 converter and connected a wire from TX+ terminal of 1st Comm module to the TX- terminal of 2nd Comm module. If I enable the hyper terminal, I see the data following but un-understandable format.

The format of data following from MSDOS PC to drives is like "7E-BF-02-04-3C-00" in ASCII format. So to read it I downloaded MS “PortMon” software which is used to monitor data following via RS232 port. I have windows XP and when I run the software, “Not Connected” is shown on the top bar. Please help how to make it “Connect” to capture the data. Or if anyone has any other idea to capture the data following, please assist.

Answer:How to capture the data following via RS232 in ASCII format.

If someone guide me about PortMon that how to make it "Connected" it would be enough for me. This time when i run PortMon, "Not Connected" displays at the top write corner.

Hi - here's an idiot question for you. I need to know whether or not my laptop (Dell Inspiron 2200) has something called an RS232 serial port. I think it probably doesn't, as I couldn't find it mentioned in System Information. But I'd like to know for sure before I fork out £30 for a USB adapter, which is what I'm told I'll need if there is no RS232 port. It's needed for a programme called DesignaKnit 7 - details of which can be found at, if anyone is interested. So, can anyone tell me how to find out for certain whether or not I have this port? Thanks v much, Helen

After several attempts at trying different driver versions, no drivers seem to load now.

These drivers are for a Prolific PL2303 USB to RS232 converter - although I did not buy the device from that company. The drivers used to install easily and I actually had one that partially worked.

At one point, I went to the Windows/System32 and manually deleted all the files and "packages" for those drivers. This likely screwed everything up and I don't know how to recover. I have the option of doing a full system recovery, but it will take days of work to arrive back at the current configuration.

After several attempts to install and uninstall all these drivers again, nothing seems to work. When I plug in the device, Vista looks for the driver in Windows Update and of course finds none. In Device Manager (DM), the annotation for the Port is Unknown device. When I try to manually install the driver through the DM, it fails. The code is sometimes 1 and other times 19.

System Info says I'm running Vista Home Premiun X86-based PC, but the sticker on the laptop says Athlon 64 X2 dual-core (Acer Aspire 4530).

Any fixes?

Well for serial ports are standard supported under Windows. In a Dos-box this should be no problem.

But pure Dos could be a problem.

I have a printer (with wireless capability) wired to desktop (Windows XP) and a wireless laptop (Windows 7). My question is, can the printer be connected wirelessly to the laptop as well as wired to the desktop, or does everything have to be wireless?
Another question: If I want to share files between the two computers, do they both have to be the same operating system? (one is Windows XP and the other is Windows 7)

Answer:Solved: Wireless Laptop/Wireless Desktop (via wireless adapter)/ printer

I would guess that the printer can be connected by ethernet and wireless, but I've never had one with both capabilities so I don't really know.

I once had a printer that worked OK connected to a network plus connected to another computer by USB. Even so, that may depend on the particular printer.

There may be two operating systems that cannot file share with each other but I don't know which ones that might be. Windows XP and 7 are fine sharing with each other (but not claiming that nobody has had any problems).

I've recently upgraded my internet provider to BT and received a BT Home Hub 3 as the new wireless router. Previous to this I was using a wireless Belkin G + MIMO ADSL router (model number F5D9630-4).

There are places in the house where the wireless signal is very poor. Connecting to the internet using either of these routers is difficult in these spots. However, since the Belkin is now spare, I've been thinking about trying to use it as a low cost repeater (i.e. free) to extend the wireless range in the house.

There are several good articles that I've found on this site which address the connection of two routers together (e.g. John Will's article on connecting two SOHO routers is a good example), but they rely on an ethernet connection between the two routers. I'm just wondering if anyone can tell me if there is a way to establish a wireless link between the two routers to extend the range of the current wireless network.

Cheers everyone, and thanks in advance.

So, I've been using Ethernet for a while now to access the internet on my PC. I never really use it because I'm always using wireless, but few months back my wireless just suddenly stopped working so I've been using an Ethernet cable ever since.

Anyway, I wanna get back to using wireless but the problem is: I don't know how. I have no wireless adapters and no wireless option to set up a new wireless connection.

I go into: Control Panel\Network and Internet\Network and Sharing Center > Set up a New Connection or Network > Connect to the Internet > But, the only option I get are Broadband (PPPoE) or Dial-Up. Shouldn't a wireless option be here?

I then look to: Control Panel\Network and Internet\Network Connections but there's only one icon there: Local Area Connection and that's my Ethernet cable which I'm using right now. Shouldn't there be a lot more here?

I've gone into Device Manager and checked my Network adapters but there's only one: Realtek PCIe GBE Family Controller. My other PC (literally, the exact same PC to this one) in the room next door works fine and has got a bunch of other adapters, I have no idea what's happened to this.

Yeah, I'm a newbie to this. Basically, I want to start using a wireless connection but I have no idea how.

Answer:How do I change to wireless? No wireless option, no wireless adapter

What is the make and model of the PC? Is it a laptop? Is there by any chance a switch that turns the wifi on/off?

If the wifi worked in the past and suddenly stopped working, I would suspect that the adapter failed but it could also be switched off or the driver got corrupted or otherwise disabled somehow.

Hi everyone,

We have a Cisco ASA5505 here that provides DHCP and routing to all our devices in our network. We also have a few other switches and wireless access points connected directly to the back of the ASA5505.

For the past year all the wireless network signals has been working fine however starting last month, none of the wireless access points (we have three WRT54G) would allow proper connection (dropping connection, slow internet).
I thought this maybe all THREE wireless access points are toast/bricked. So i went out and bought brand new Netgear WN604 and even with the new WAP i'm having same connectivity issues (really slow internet).

When hardwired directly to the switches we get BLAZING fast internet & connectivity, no issues.

I called CISCO TAC and asked them for help and they automatically said "our ASA5505 is fine, it has to be your wireless access points" not working properly. I explained to them that i also purchased two brand new access points and they are doing the samething now, how can that be?

Hello everyone, Just received my new Thinkpad X210 series laptop computer, and it was supposed to have the Intel Wi-Fi link 6200N AGN, and also WWAN ready, with Bluetooth. However, when I open up Device manager, I do not see this adapter under Network Adapters, as I only see the Bluetooth Adapter. I also cannot connect to my wireless router, nor does it see any wireless connections, as I am using it right now on another computer. Can someone please tell me if this feature has to be "turned on", or what? Also, when I try to diagnose my internet connection problem, there is no option for wireless connection. I do see a symbol that is lit on my screen, or right below the actual screen that shows the bluetooth symbol, and if I move the switch that is on the left forward side, it will turn the bluetooth off and on. I can't believe this doesn't have the Wi-Fi link card installed. Is there something I have to do to enable this, or to at least let it show up in the device manager? I also turned off the bluetooth switch, and if turned off, it too does not show up in device manager. So before I hoot and yell at someone who sold me this, I better find out if there is a turn on switch for this wi-fi adapter to activate. Any help will definitely be appreciated, or I will have to wait another day to call tech support on this issue. Many thanks and I look forward to reading to staying on top of things by reading everyone's remarks on this forum.

Hi All,

Here at work we recently had an access point installed for customer access to the internet. We have had no problems with anyone access the network until today. I am not that knowledgeable with wireless so please forgive me if I fail to give you what you need to help.

D-Link DWL-G700AP Wireless Access point

normally customer just click on connect to networks and their adapter finds the many wireless networks in our area (about 8). They choose our network and type in the network key and they are connected.

We have a customer in this morning (now) that cannot connect.
Here is what I have found:

If you click on the wireless icon, choose connect to any network. You get: "Cannot find any network."

I then setup a connection manually; still does not find networks.

Here is the weird part: If you go into the Control Panel, choose Wireless Config Utility; Dell Wireless WLAN Card Utility, Choose site monitor site. It shows a list of the wireless networks and there signal strength. So the wireless adapter is receiving the wireless signals, but will not connect or show them in the list of wireless networks.

I would really appreciate help in figuring out what is keeping this computer from connecting.

Answer:Wireless adaptor cannot find networks, but shows signal levels in wireless utility

I don't understand "It shows a list of the wireless networks" in the same paragraph with "will not ... show them in the list."

I have a laptop dell xps M1210 with Intel(R) PROSet 3495 ABG. It has been working well for several years.

Yesterday morning I got an error: "Problem applying profile", then it couldn't been connected.

I did a lot of things.
1) Update the driver from 10.5 to version 12.1
2) Make sure "Wireless Zero Configuration" service started.
3) Uninstall the wireless adapter and reinstall it.
4) reboot the machine.

It is not working today. The error becomes "Intel(R) PROSet/Wireless Software was unable to detect a supported wireless adapter.".
By checking the device manager for connectivity, everything looks good.

One thing I must mention is sometimes I got an error that is "Microsoft Help and Support Center has encountered a problem and needs to close...."

The detail is Error signature
AppName:helpctr.exe AppVer: 5.1.2600.5512 ModName: ntdll.dll
ModVer: 5.1.2600.5512 Offset: 0000100b.

I am frustered but I don't want to reinstall windows system.
My OS is win xp pro sp3.

Thanks for your reading and help.

I have a problem with my home wireless network. My network operatates at 2.4 GHz and so does my home wireless phone. Everytime my phone rings I get disconnected from my wireless network. Is there anything I can do to fix this problem?

Answer:Everytime my wireless home phone rings I get disconnected from my wireless network.

Welcome to Tech Spot

Do you have 802 B or 802 G wireless?

When I was in Best Buy, one of the sale people mentioned how 2.4 GHZ phone interferes with 802 B Wireless networks (uses same frequencies).

He mentioned that 802 G wireless network were not affected with the phones.

Hey guys, need some urgent help here.

I have a program on my computer called Intel(R) My WiFi Technology, which has something to do with my network adapter (Intel (R) WiFi Link 1000 BGN). I recently had an annoying notice popping up from this program saying 'The Wireless Network Adaptoor could not be found'. So I decided that I should find a solution on Intel's forums. I came across a thread that discussed my problem, and one of the Intel workers mentioned that Uninstalling and Reinstalling the program would be the best solution. So I followed the steps and came across a huge problem . Turns out that once I removed this program, my computer wouldn't connect to my wireless network in my house. I went onto my other devices throughout the home and they all seemed to be working fine, and that my router was still working fine aswell. I went onto my other computer and downloaded the program onto my USB, and installed it back onto my original computer. There still wasn't any difference, and my computer still currently can't connect to my wireless access point. I've rolled back drivers, updated them, and I've refreshed wireless network adapters in my Network and Sharing Center in Control Point. I'm starting to run out of ideas, and I really need some help. My computer can still detect networks though, but I've discovered it can connect to my Mobile Phone's Access Point, meaning I can connect to 3G through my phone. I'm sus... Read more

What is the highest speed possible when connecting the wireless-AC wifi card to a wireless-N router? My wireless-N machines get 100Mbps speeds on my wireless-N router but the wireless-AC machine only gets 35Mbps.  I understood "AC" to be backwards compatible with "N".  Is does connect but the speed is much lower than the "N" equiped machines. Do I actually need an "AC" router?

I have recently sorted out the wireless connection of a child's laptop to a wireless printer. It works perfectly. Howver, the parent's, wired, desktop computer does not now print. No changes were made to the desktop , which was working fine before this.. I am not at the location now but are there any ideas why this should suddenly occur. Both computers are running XP.

Answer:Wireless printer not printing from wired computer after connection by wireless lapto

Wireless printers can be connected both by USB and wireless simultaneously. However, I have come across many that say they should but don't do so easily. Sometimes they have to be setup wireless first then USB and others vice versa..
In my opinion, it is probably the best option to add the printer to the desktop through the network. Then there should be no problems with setup. Hope that helps..

Greetings fellow friends,

I recently moved next door to my new IT job. Quite literally, its an old neighborhood with many commercial complexes, and some old houses from the 40's. My company bought the property on both sides of our building incase the future requires expansion and for now I am living there! Woot, no more drives to work!

Our CTO said it's fine if I use the 30MB Fiber Optic broadband for my own personal use at home, However he is not willing to allow me to run CAT Cable to my house. I installed a Wireless Router (WRT54G) using Tomato 1.25 underneath a desk nearest to my Basement Bedroom Window, and am able to receive excellent wireless connectivity VIA Notebooks and other devices throughout my house.

However, My desktop computer does not have a wireless card and I do not plan to put on in due to resource conflicts, and I do not like what Wireless Interferance does ocasionally.

I thought it would be best to goto the store last night to buy another router, this one was a WRT54GL and I flashed it to Tomato 1.25 immediatly.

I attempted to use Access Point + WDS mode as highlighted in this readme (How to use WDS?)

I run a private network using PFSENSE on 10.8.20.* ranges, and there is DHCP. When I connect wirelessly to the router under the desk I receive a 10.8 Address via DHCP which is carried from our primary network/routers to the Wireless Router, And then to me.

However, what I want to d... Read more
