Have a VirginMedia Hub3 and up until 2 weeks ago ran a powerline set up with three extenders. This worked fine with no issues.
Two weeks ago the two additional extenders stopped working although the LED lights show that they are still paired. Have reset and paired again but will only pair one. I can pair all of the extenders but only one at any time. It doesn't link the other two no matter which combination of extenders I try.
No problems with hub according to VM.
Some very unhappy kids at the moment due to lack of WiFi and frustratingly I've tried everything I can think of (including speaking to TP link help desk and nothing is working)
