Good morning,
I have had a TP-Link AV600 for a year now; I live on two floors and until a month ago the router was located in the attic. After switching internet companies, I placed the new router downstairs.
Now the powerline doesn't work anymore, or rather, if I place the receiver on the lower floor it works, if I bring it back to the attic it doesn't work anymore. What can it be? I have already done the reset.
