Two AIR-AP1231G-A-K9 APs are on different ports of the same 3550 switch. Both ports are configured the same.
One AP is running c1200-k9w8-mx.124-18a.JA1 and associates with the4402. The other is running (C1200-K9W7-M), Version 12.2(15)JA, RELEASE SOFTWARE (fc1) and doesn't.
Could the older software be the cause of this?
