I have the exact same problem. Had a wired connection straight to my laptop working fine for 2 months. Went to Dubai for New Years a week back(used wireless in the hotel there), came back, plugged the cable back in and I get Unidentified Network - No Network Access. Wireless to other networks is fine and my dongle works too. I've been looking for a solution for 2 days now, trying everything with no luck.
