I've had my Deco P9 (3 units) mesh system for about 8 months now and until recently it has worked flawlessly. However about 10 days ago we started to notice devices on wifi would just lose connection and it would take a minute or so for the connection to be restored. I tried all of the typical things like restarting each unit, disconnnecting and reconnecting to wifi, I even unplugged the two sattelite units for about half a day to rule out a bad sattelite unit. Finally I designated a new main unit but that didn't fix the issue either. I played around with settings in the app to no avail until I disabled the 5G band, after that things seemed to work fine. I left 5G disabled for a couple of days but when I re-enabled it last night the same issue started to happen.

Here is the fly in the ointment (I think) around the time this started to happen I switched cell phone carriers and went with Google Fi. Last night when I re-enabled the 5G band on the P9's and started losing connection again I decided to try disabling wifi on all cell phones in my house. After I did this the issue stopped again. Now I only spent about 3 min testing this before I got tired and went to bed so it could just be a fluke but it seems like Google Fi and TP-Link may not play nice together. I realize this sounds like a conspiracy theory but it's difficult to ignore the results.

Anyway, has anyone experienced something similar? I've seen a few Wifi dropping threads on here but I've tried the suggested fixes in those and had no luck. At this point I'm open to any possibility though.
