I've just had to do a fresh install of XP on a new hard drive on my main PC but now it won't connect to my router no matter what I seem to do.

Its a Belkin wireless G router/modem, this PC is running wireless through it no problems, and the XBOX and 360 are also running through it with no problems either

I've changed the network card settings to point at the router (IP address, subnet mask) and the DNS addresses for the internet but when I put the router address into the explorer address bar it just won't look at it

The router has got the light on it saying that the PC is connected and everything worked fine before the old hard drive gave up

I'm really losing my patience with this, anyone got any suggestions?
