Wireless access keeps getting disabled after upgrade to HAOS 13.1

I have always had “dual” access to HAOS running on a RPi5 via both eth0 and wlan0 – that way if access to one interface is lost, I can still access the other interface.

It seems that at or around the time I upgraded to HAOS 13.1, I lost the ability to connect wirelessly.

Specifically, wlan0 is up and connected to my wireless router but there is no ip address – I obviously can’t ping or connect wirelessly.

It turns out that the wlan0 interface (under: Settings->System->Network) was switched to disabled and the SSID & password settings were lost.

I thought that was a one time event, but it happened again.
I have never had this problem until now.

Any idea why this might be happening… and what I can do to prevent it from losing its wireless settings again?
