Trouble with AP2750 (online and offline)

[Luis Ramírez V.]

We have a WX4400 switch with 8 AP2750, all of them using power adapters because we don't have PoE switches.  One of the AP has troubles since two weeks ago: when I connect it, it's showed in the admin web page, but, after a few minutes, it appears disconnected.   I reset it several times with the button, but is the same behavior.   I tried to connect it in differents switches but the same: disconnected after a few minutes.   Also tried to change the power adapter and the patch cords but with the same trouble.

I would like to know if there any other test that I can do to the AP2750 in order to see if it's damaged or something that I can fix.

Thanks for all your help
