Hello, I have 6 deco network right now.

the signal in some are not full but the problem is when looking at the main deco speed wish does not match the speed of the source (120mb) it's always going up and down mostly under 1mb 

i don't really know what to do, the other decos are the same and was thinking of getting more since riz signal is not perfect, but since the main one is the same I'm not sure that's the solution.

this is the on the other extreme of the home
