@Rhyalus I have the firmware you mention. I have 5 of these so am heavily invested. 

I first noticed my Eufy doorbell going offline.

Then things constantly disconnecting. 

The network has also slowed down considerably. 

  @Rhyalus I upgraded to .11 and all of my Google devices stopped working.

I have 
2.4 GHz only
WPA2
Fast Roaming disabled
Beamforming disabled
