@Solla-topee I tried with the original 1.0.0 Build 200819 Rel.60695 and updated to 1.0.0 Build 210324 Rel.31439n (8583). Factory reset works as expected, if I factory reset al units they work...

@Solla-topee | When the network name become Unknown, does TL-WPA4220 still work fine at that time? It seems to be working fine at that moment, but it blocks after a few minutes, or hours sometimes....

I see the same thing with my adapter. The one that doesn't work and keeps as "Unknown" is a wpa4220 V5, the other is V4.
