WD Livewire

I have three WD Livewires which were working until yesterday.

This morning the unit plugged into the router will not connect to the network (no PLC Link light). I have tried switching all units off then on and trying resync, factory reset using the pins on bottom, and have swapped out the main unit with a brand new one, which also will not connect. No luck so far.

Ideas?

Try connecting the two livewires to the same wall socket to see if you get the same problem,
