I have a WD Livewire powerline ethernet kit installed (two units) and working well. I want to add a third location. Will another brand that is HomePlug protocol work? I can't find a "single" WD unit. Thank you.
Which WD powerline did you have? is the 85Mbps or 200Mbps or 500Mbps one?
If it is the WD-85Mbps powerline adapter, with the protocol homeplug 1.0 so you just can buy the 85Mbps one.
If it is the WD-200Mbps powerline adapter, with the protocol homeplug AV so you need to buy the 200Mbps.
It is rare to find one boz it usually sold by one pair=2 pcs. but nothing is impossible
