Hi,

I have three PA7010P that has worked like a charm. Now one of them started acting up when we where away on vacation. 
 

My UniFi AP that was connected through a switch that gets internet through the powerline disconnected.

I have tried skipping the switch, nothing. The Powerline shows a connection but it does not work very good. I think it might have something to do with UniFi getting updated with a new v9 network Application but I cannot guarantee it.

Now I unplugged a lamp in a close by outlet and it looks like I get internet again. Luck or could that be it? 
 

have put a lot of hours into this and have seen short bursts of connection.
