@saratoga Interesting. So you are running your devices in standalone, and presumably have an unmanaged L2 switch between the router and APs? Have you configured any VLANs, say for your SSIDs?

@glock-kai Just don't enable VLANs on them (which will tag packets) and they will work like a dumb switch on the default VLAN of the AP.

@Kimijoe Then my guess is the power circuit in the AP is fried which is causing the adapter to shutdown to protect itself. Power surges are bad and this is not unheard of. Sorry, but it is probably...

Have you tried defaulting the AP by inserting a pin in the hole next to the ethernet jack and depressing the reset switch for 15s or so? AP must be powered up when you do this.
