I just bought this yesterday

Powerline cannot pair between Living room(behind TV set) and Master room (same floor in a condo about 5m physical distance).

For betwwen two sockets Living room and walkway (different walls about 3m),,it pair with about 60mbps.

For two sockets next to each other behind the TV set, it pair to 500Mbps. but this has no practical use.

Is it possible the unit is faulty? The performamce seem too low
