When I have these settings enabled, non-6E devices will get kicked off the network. When attempting to connect, the devices ask for the password. Re-entering the password, no matter how many times, will not allow them to reconnect. A reboot of the Deco is required to allow the devices to reconnect.

WiFi 6E - Enabled with unified SSID to 2.4/5GHz

Beamforming: OFF

Fast Roaming: ON

I can maintain stabiilty on the network by configuring 6E for backhaul only.

The Deco nodes are connected via Ethernet so the backhaul is not in use.

Is this an issue with the Deco or an overall issue with WiFi 6E compatibility with older devices on the same network?
