We have a wireless network at my house (all of our computers run Windows XP), the router is a WRT54GS and all the PCI adapters are WMP54G (v2 I believe). For some reason, my computer won't connect to the network, sometimes it will say it is connected and has a speed of about 28mbps, but it isn't really connected to the network. And when it is REALLY connected to the network, I get speeds of about 1.0 mbps and any network activity that goes on for more than 15 or so seconds causes it to disconnect. I have tried manally entering all the IP information (IP of 192.168.1.128, Subnet Mask of 255.255.255.0, and Gateway of 192.168.1.1, as set on the router) I had this problem once before, after all else had failed, even tech support, I tried reinstalling windows, which did work the last time, but now, after two attempts, that hasn't even worked. The adapter stopped working correctly after installing a GeForce FX 5500 OC (PCI, 256mb) in my computer, if that is even at all relevant. Please reply as soon as possible.
