Starlink Gen3

Archer AXE75

3 Deco X75 tri band

2 Deco X95 tri band

Starlink broadband with Archer AXE75 connected in bypass mode, and home mesh network using 3 Deco X75 and 2 Deco X95 . The wi fi coverage is poor and dropping out ithough 4 decos are placed primarily over the ground floor and single deco in the first floor. The network over the deco app looks good with week signal over two decos where are placed in the south end of the house smart thermostat can not controlled remotely, security camera disconnect frequently, Sky Q and mini box stops due to losing internet connection.

The internet speed vary across the property hence security camera and sky Q. Box and mini box, constantly lose connection, these and other smart techs Smart Flower and Tesla Battery, Smart Alarm system are all connected by Ethernet cable with boosters to ensure undisturbed connectivity

The Pro installaer of the Starlink and the home mesh network is at loss where is the problem, the home mesh system with high performances should cover the property with seamless wifi through out the property and on average internet speed. In fact one room speed test recoded at 200Mbps, the room next to it or the hall register speed of 22Mbps in the same floor. What's is happening , why this dropping out of internet speed and Wi-Fi cover 

Would another wireless router needed to cover the part of the house with poor signal and low Wi-Fi coverage?
