Windows 7: Unidentified network/no internet access

Hi,

I did check the other threads regarding this issue, but they didn't return a solution for me.

I have internet acces through my 3G card, but I also want to connect to my wireless network using my wireless card.

The device I am using is an EXOPC. I have tried removing the adapter, disconnecting etc etc. But the network keeps on showing up as Unidentified network. There is is no popup for me to seelect the network type to be either home, business(? ) or public.

Last weekend the bluetooth/wireless card has been replaced because bluetooth wasn't working on the old one. We have reinstalled the drivers, but didn't test wireless afterwards...only bluetooth.

What should I try next? If nothing helps I will do a restore, but I hope that is not neccessary

Today I tried some of the unsecured networks here in the area. They do connect and provide internet access.

Can it be a problem that this new Wi-Fi card has a different MAC address, but the rest stayed the same?
