2. Put 2 powerline unit in the wall sockets, in the same room, and pair them again :
Paring Note: press Pair button only for 1 sec, Power Leds should be flashing on both powerline units in pairing process. ( if the Power Led does not blink, press it for 1 sec again)
When the Powerline Led or House Leds are on, the pairing process is done
3. Connect main powerline unit to router via Ethernet cable, and put powerline extender in another room
If still the same problem, please let me which step you met trouble and the Leds on both powerline units, thank you,
