Problem connecting to wireless router.

Ok, the issue I'm having makes no sense to me, and I've been working on it for hours now. Basically what's going on is this: I have a USB TRENDnet wireless card for my desktop that connects to a Linksys wireless router. It has been working fine for me ever since I got it, however yesterday it all of a sudden lost connection with the router. I repaired the connection, as we were having some problems with the router where we would need to reset it every once and awhile, but the repair didn't regain my connection.

Now when I plug it in it will detect the wireless network, and connect to it but will not get an IP address for anything. I have reset the computer, reinstalled the drivers, and even reformated the HD, since I had been meaning to do it soon anyways. Nothing helped. My dad tested the card on his laptop, and got it to work just fine. There are two other computers on the wireless network and both of them can connect just fine as well(with different cards).

I ran IPCONGIF/RENEW and got the following about my wireless connection: unable to connect your DHCP server. Request has timed out.

I tested another wireless card in the computer and had the same problem as I have with the USB wireles card. I'm pretty much out of ideas as to what I can do, so any suggestions will be appreciated.

 

To get you moving, I think the first thing to try is to work out if the problem is that the DHCP service is not working, or that the reason you can't connect to it is because the network isn't working. To do this find out the IP address used by the router (commonly 192.168.1.1 or 192.168.0.1) and statically assign an address to USB wireless card. You can use this tool to try out addresses that should work with your router. Enter the router's IP address as computer 1 and the one you want to try as computer 2. In general if you take the router's IP address and add 7, you should be alright. So if your router is 192.168.0.1, set up your USB adapter as 192.168.0.8

If you can connect with the static IP, it is a DHCP problem. If you still can't connect, it is a more fundimental network or hardware problem.

 

Reggie, I set up my computer for a static IP but I'm still getting "limited or no connectivity ". Additionally, windows is not always detecting the card when I plug it in. I have tried different USB ports and it's the same with all of them, sometimes it'll be detected and sometimes it won't. This leads me to believe that my issue may be a hardware one, but I'd appreciate any other ideas that I could try before coming to that conclusion.

Additionally, there may also be a driver conflict somewhere or a problem with the utility that came with the card. I'll have to try and look into that as well.
