Why does wifi on powerline adapter disappear accidentally every a few months? 

And I can't manage powerline device over web(on home network) in the same time.

Need to unplug and plug it back in order to recover(wifi one ,not the one plug on home network cable).

WPA4220 is not reliable.

TL-WPA4220 v4.0
