I'm on vacation in Mexico here, and I have wifi internet access in my room, and it's worked great all week long, until today when I applied the "Security Update 2008-005". Immediately after restarting the machine the signal got really lousy, and I have problems keeping the connection. Before the install/reboot it was stable and I had no problems at all. Now it just keeps falling out. Opened AirRadar here, and it shows the signal going from 20% down to 0%, then up again etc etc. Anybody else here have problems or suggestions for how to fix this?
