I'm trying to run a wireless network at a tradeshow. One AP has 2.07 firmware and works fine. The other has 3.04 firmware and won't maintain a connection. Is it possible that the convention center is somehow "jamming" the wireless networks or am I just being paranoid? If they are somehow inhibiting wireless networks, why does the old firmware work OK? Is it more robust? Any words of advice would be a huge help. The show starts Monday. It's at McCormick Place in Chicago. Thanks in advance for the help.
