I havce just built a computer and had a few teething problems, but all is sorted now i think and i have got windows installed etc. but driver cd kept crashing a few times, eventualy i think i've managed to install all of them, but now i having trouble connecting to any wireless network....it wont pick any up at all::
Asus p5w dh deluxe
core 2 duo e6600 2.4 ghz
7900gtx 512mb
2gb corsiar ram
etc etc

they are the main bits...but any ideas why i cant pick up my home netowrk (along with others), which i have been using on 2 other laptops on a daily basis (PS its nothing to do with putting in a network key etc .... i cant even see any networks available)

Welcome to PCMech.

This is an existing wireless network router you'd been using but a new desktop card, right? What models? Is the card's software working on the new computer, for example can you run a site survey or anything?

Is the wireless card installed and properly working according to device manager?
