My friend's Amilo running Vista Home Premium refuses to connect to his new router's wireless network. My Dell, sitting next to his, connects immediately, and his Amilo connects to my wireless network at home with no problems.
Vista simply says 'Cannot connect to SAGEM123 network'.
I've tried turning off encryption but it still refuses to connect.
(I have a feeling that I've seen a similar problem and it came down to an invalid passkey being entered initially and then despite re-entering it when prompted, for some reason Vista never overwrote the incorrect key).
Any ideas please!!
