Since this firmware update, 4.6.9.11, all my devices have kept dropping off the network.  Having issues with Kasa plugs and my cameras.  I did a factory reset and still having the same problem.  I called Netgear, and they said others are having the issue and go back to Firmware 4.6.8.5.  I was still waiting for second-level support to call.
