ello, 

I have 3 Deco X60.  Two satellites are version 1 with the latest build. one satellite  is version 2 with the latest build as well ( Version 20210204 Rel. 50164). 

My main Deco is a V1 and the two satellites are V1 and V2. All of the satellites are connected to the main unit via one switch and Ethernet back haul. 

Some of the satellites also lead to other switches for wired connection to playstation and office computer and printer. Iperf3 test show that Ethernet bandwidth is near gigabit. Main unit is in basement other satellite on ground floor and last satellite is in attic there are no satellite on second level. Signal is strong everywhere but I do not have WIFI 6 devices. 

For some reason, I frequently get loss of connection on wifi  (tablet and phone) and have to restart streaming apps to keep watching the show. It  takes a few seconds before the streams get going again. I do not get this when I am wired. I have enabled and disabled  fast roaming and that has changed nothing. Fast roaming seemed to make this worse. Can anyone provide advice. Here is some ofvwhat the system log is showing ( identifying information has been removed):
