Got a bit of a problem with a new RB912UAG. I had it set up as an access point using the built-in radio, working fine, but now after taking it on a flight across the Atlantic none of my devices can see it any more (or they see it with worse than -90 dBm signal strength). I've tried a reset, and the AP is active with normal transmit power. I've also checked the pigtails and scanning the neighboring environment shows both weak and strong signals, so I assume the RF hardware is functional.
Any suggestions for things I can test, ways of debugging this?
Only thing I can think of is that the power adapter, an EU model and I'm now it the US, is not giving the AP enough power despite the adapter being rated for 100-240V. Don't have another I can test with yet, however.
That, or somehow just both TX chains broke...
