TL-WPA4221 KIT - AV600
Hardware Version: TL-WPA4220 5.0
Firmware Version: 1.0.12 Build 230309 Rel.64136n (6985)
A few days ago I updated to the latest version (from 20220613-rel68081) but the device disconnects,
 disappears from the network and does not respond.  I have to unplug it and plug it back in to make it accessible again.
When it works it's great, better than the previous firmware version. Unfortunately, it is not possible to downgrade from this version.
I'm looking for help to solve the problem.
