Hi and welcome
I've got a problem with wifi. The connection either is ok, Windows can connect to the network or I am connected but have no internet access. I'm connecting via a router.
I'm having a normal PC (not a laptop), the network works when I'm on XP but it doesn't work on Windows 7.
I've downloaded newest drivers, disabled IPv6, tried static and dynamic DHCP.
I've noticed that when there is a problem with the connection I get a "WPA retey failed" error on the router. I've searched for that and basically the solution was either to use WEP (don't want it), try static IP or different channel (the wifi works on the same channel on 3 XP computers so I don't see that being the case).
Do you have any other ideas? Well... except from "We're sorry but microsoft doesn't support your router, go and buy another one, maybe it'll work then.."
