Take the IC and the 2 caps above it off the board and clean the board with alcohol. Take the old solder off and resolder the taken off parts with fresh solder. See what that does. Other than that you can try to replace the IC. Usually antennas are DC grounded, so you should measure a short. The 4 LED's on the top on the case are for signal strength, then there is LAN activity and a power LED.
I think you have a problem with the feedback circuit. Probably something is corroded.
