Hi

I have had the system just short of one week now and so far I am not impressed. Yes it's boosted my speeds however it's constantly dropping my WiFi and it's not ideal as I work from home. 
 

My main router is in the living room and my main mesh is connected to this through a new cat 8 Ethernet cable. 
 

my WiFi routers gets 530mbp and is producing 80mbp WiFi - its virgin media. 
 

My other two decos are on the hall landing (about 6 metres through the wall from the main) then one in the upstairs room (room above main deco) and this room is adjacent to where I work. 
 

doing a test I can get about 40-200mbp from my deco system, but it constantly starts and stops and means my work system stops for minutes at a time. 

I've done optimisation too.

please help-at this rate it's getting returned.
