bought a new router yesterday, and after swapping it out for the old one, something weird seemed to happen to the powerline network I have in place. No problem, I thought ... I'll re-pair the adapters (TP Link PA201s).
First 2, no problem. Then I tried to add a 3rd, using the socket next to the 2nd. For some reason it just refused to pair. Then, after a cup of tea, I went back to it, and it was paired (the "PLC" light was on).
However, try as I might, I cannot get the 4th powerline adapter to join the network. I've out it next to one of the already paired ones, and tried every combination of pressing pair on the new one first, old one first ... but no, the 4th adapter refuses to pair.
Can anyone suggest anything to help ? The 3 paired ones are blazing away at 150Mb (according to the utility) at 80% signal strength, so I can't see it's a mains wiring issue.
