I ran Windows 7 Beta on my HP Pavilion laptop tx-1000, with it's internal NVIDIA nForce wireless adapter supporting b/g and n. It worked fine, then yesterday I loaded RC1.
Although the wireless connect SEES all the wireless networks, it can't connect to any (of mine, two total).
I've removed all the security from them, and connected to them with a desktop with a PCI wireless adapter, so they're good.
Did the driver set change from Beta?
Is there a comprehensive diagnostic process to determine WHY Windows 7 can't connect?
