Poor connection around the flat

[EH5]

In addition to my Sky hub I have 2 plug in boosters and a further white booster hub with 3 green lights showing 

the plug in boosters have lights which fade, the light comes and goes.

in some rooms the Wi-Fi connection disappears

@EH5 There is a point that having too many boosters causes more havoc than good, hope that you are aware off that fact.
