Hello,

I have the TL-WPA4220T kit with two TL-WPA4220. 

Randomly you don't get internet access from the devices. The router works just fine, just the powerline doesnt work.

I've tried pretty much everything to fix it but it just keeps happening.

I've upgraded the firmware, set the devices up again, hardware reset them etc.

Then I thought a multiple plug with a surge protector was the issue (which was powering my pc not the powerline thing), but removing it from the circuit changed nothing.

The weird thing is that sometimes the LAN works while the WIFI doesn't and vice versa.

Also the Powerline LED when it doesn't work.

Is there anything more I can try?

Help would be much appreciated, thanks.
