Could I join with my pain?

I did upgrade from Breeze to Dapper by changing repositories name in apt 
config (devil incite me). Everything looks fine except network 
connection. My "D-Link AirPlus XtremeG+ DWL G650 Wireless Cardbus 
Adapter" did work good before upgrade. Today it haven't see any network.
I think the situation is similar to your, hardware definitely can work.
What should I do to restore connection?
