Orbi 850 running V7.2.8.5_5.1.21 dhcp issues

In order to test we may need to reset all of our end-points and reset the Orbi back to router mode. All up about an hours effort, not counting reconnecting some 40 lights back to the app.

The way most devices to wifi works is that they won't disconnect from a sourced until a lower level signal threshold is dropped below. There are also "hold timers" before switching. Again the issue here isn't the wifi connectivity but rather the DHCP function. I've read that "slowly adding" devices may help but that is all just a work around for what appears to be bad software, firmware or hardware.

I've also not been able to find anywhere that this is resolved in later models.
