>Description:
Connecting to WIFI in Wings Restaurant in Mexico City Airport causes system freeze.

I connected to infinitum movil network in Mexico City airport several times w/ dhcp without trouble. Went into Wings Restaurant and connected to their AP. device associates but ip is 0.0.0.0... get a couple of errors in syslog then system freezes solid. I tried 5x and same behavior. Reconnecting to infinitum movil outside had no issues. Might want to check it out. Wish I had more data/stats, had to catch a flight. May need to fly to Mexico City Terminal 2.
