Been dealing endlessly with tech support and tried various wifi adapters but won't bore you with the details. I just installed a PCI wireless card (Edimax EW-7722In) and also have a Broadcom NetLink Gigabit card (not wireless).
Basically, everything works fine on other computers in the house so I know it's not the router. The drivers for both the wireless and Gigabit card are correctly installed and even worked earlier today for a while. But now I get no connection and the router seems to be unable to assign me an IP address. DHCP is on, I've tried hard-rebooting the router, taking out the wireless card, and all the other standard stuff.
I've tried manually enterring the IP address, DNS and gateway but that doesn't work either.
IPconfig gives me something very basic:
Tunnel adapter Teredo Tunneling Pseudo-Interface:
Media State .............. : Media disconnected
Connection-specific DNS Suffix . :
And nothing else. I've reinstalled the drivers, disabled and enabled everything, tried all permutations I can think of but nothing works. Any help would be massively appreciated.
