Hi 

I have a three-pack Deco M4 system that appears to be working well, but regularly loses wi-fi connection to all connected clients. Sometimes it loses connection more than 4 or 5 times an hour, and I know this because my TV tells me that no network is found, and my phone and desktop computers also show no network. This lack of connection is very brief, perhaps only a few seconds, and then everything reconnects satisfactorily. It is annoying as the TV picture will sometimes freeze/lose definition, and my connection to the online apps that I use for my business keeps having to reset. 

I have disabled the wi-fi option on my router, and I have regularly optimized the network, so there is no apparent interference - not sure what else I can do. 

My broadband is stable with no problems (45mb download speed), so this is definitely a network connection/wi-fi issue.

Please help
