i just bought a new wireless card (http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=260471276252&_trksid=p2759.l1259) to put in my medion akoya 3300 which previous to this always had a wired connection. i installed the vista driver just fine, under device manager it says all is fine but when i try to connect to a network it just says windows cannot find any networks. i have a psp and ps3 in the same room both of which get between 80 and 100 per cent signal. i have tried everything i can think of, set up a manual connection, put the card in a different pci slot, re installed the driver. nothing worked. i am going out of my fukcing mind with this thing, can someone please help.
