Hi, I bought and installed three P9,s acouple of months ago and they worked brilliantly for just over a week. Without any notice the speed fell to 0 or a couple of kb’s. All Decos were showing the solid white LED, they were all connected but the speed had dropped. I turned the WiFi frequency’s on and off and everything came back to full speed. About a month or two later the same thing happened. I can’t get it to work at all now, just showing 0-4 kb’s on all connections. 

The router is fine and I have normal speed on WiFi from it. I have tried forgetting the network and reinstalling from scratch. I have done this twice, most recently swapping the ‘main deco’ for one of the other two in case this was a hardware fault. It hasn’t made any difference. 

In summary everything looks right but there is no speed. 

Any suggestions?
