Faulty 3702 AP?

chris.brunt

Level 1

I have two 3702I ap's in close proximity. One is working fine and the other is resetting it's 5ghz radio every 30 seconds.

I'm thinking this 5ghz AP radio is faulty as I have tried different channels (widths 20mhz/40/80), set them statically, rebooted, factory reset. Swapped switch ports, the other AP on the same channels has no issues.

The AP is primed correctly and shows on the controller with the correct reg domain and country code.

Here is the terminal of the AP.

#if possible console into AP and get - show cont d1, show cont d1 | i reset, more event.log. these log provide clue on what reason it may be failing.
#Reboot the AP, at the start it should say radio1 is fault or not.
#If incorrect country code enabled on WLC or incorrect reg domain AP used, The WLC's msglog would show that.
#Possible RMA due to PCI reset(hardware related).
