PC wireless nightmare

Hi,

A few months ago I set up a wireless router and added PCI wireless cards to our 2 desktops. Mine's worked fine since the install, laptops connect up no problem (insert WEP pass and away you go) but the other PC's situation keeps getting worse. The first sign of problems was when the wireless connection speed given in the connection details screen started dropping to 1mbps (from 24+ usually) consistently whenever a browser was used, and now connecting to websites either takes a few minutes or doesn't work at all. Strangely email software would still work without these massively lagged responses though! When I first set up the PC I think it would connect via DHCP without putting manual TCP/IP settings in but now you have to specify everything otherwise the "this connection has limited or no connectivity" warning comes up and it never works... Although this problem arose some time before this sudden nigh-complete failure. I've tried just about everything I could think of at the minute:

- changed wireless network settings - channel/encryption etc
- swapped wireless cards, both perform exactly the same on the other yet work fine on my pc
- uninstalled drivers / removed card / reinstalled drivers / added card (in a variety of orders)
- tried different PCI slots to no avail
- repaired windows
- formatted & reinstalled windows

So I suppose it's most probably a hardware problem with the PC but I have no idea what it could be. Any thoughts as to what else I could try to get it working before I have to end up taking it to PC World so they can tell me they have no idea too and try to sell me a new one? :whistling:

1: Have you changed the position of the computer or the router? Is there anything that may interfere with the reception?

2: Have you re-installed the chipset drivers after format?

3: Try a USB a wireless adapter. It might be that something is not working well on the PCI slots.

Yes, I did install the chipset drivers after reinstalling windows, although the computer seems to be suffering the odd freeze for no reason I can't see why any drivers would be different to what they were back when the connection worked. There are no driver conflicts, I've tried resetting the TCP/IP and winsock to no avail. Also turned off MAC control and my WEP settings but that hasn't helped either. The connection still stops at "acquiring IP address" and I can't access the router's setup page. It's bizarre :whistling:

After trying to configure the connection - specifying IP/gateway(router)/DNS servers(ISP IPs) manually - the router page loads incredibly slowly and the internet still doesn't work. Any more ideas?

ipconfig /all results say Dhcp.. No whereas all the other comps connecting have Dhcp Yes and Autoconfig Yes!

Well I've been through all that of my own volition pretty much. Can't check if it works with a cable as the comp doesn't have a suitable port. I'm going to buy a USB stick to see if I can receive with that, otherwise it might be time for a ceremonial desktop burning :whistling:

btw
Router: Safecom SWAMRU-54108
Cards: ASUS WL-138G

I've checked the IRQ assignments and everything has a different number so I assume it's fine there. I did try IE/firefox but now it's refusing to even find the wireless network.. I'll try mucking about with drivers again.

On an unrelated note I've been having occasional IRQ_NOT_LESS_OR_EQUAL (or something to that effect) blue screens on another PC and it has two items on the same ISA IRQ and four lots of two on one PCI, could that be related?
