Firmware v. 1.1.1 Build 20200716 rel.84595(5553) messed up device discovery
Since the update my Sonos speakers have vanished from the network and I can set them up. They are not found during the setup.
Wifi TV remote also stopped working. It can't find the TV anymore.
I've tried factory resetting to no avail.
1) what's the solution?
2) how can I disable automatic firmware update on the router? I am unable to downgrade from this version.
