After a solid year of running great one of my Aironet 1142N access points started acting up on me. Yesterday, both radio interfaces changed to 'reset/down' state for some reason. The only way I could get them back to 'up/up' was to reload the access point. If I shutdown the interface and brought it back up, it would then display 'up/down'.
I thought it was fixed but today the wireless was weak again, so I checked and now just one of the radio interfaces is back to 'reset/down'. Reloaded the access point and we are back to 'up/up' and great coverage again. Think it could be a hardware issue, or am I overlooking something maybe?
