Cannot connect range extender to Virgin media wifi
I have problems with WiFi in my house and garden, I have a virgin media router. Virgin media supplied a range extender but I still have dead zones. I had a TP link AC750 range extender but that will not connect earlier by using the WPS button or with a Lan cable. I thought the AC750 was not working so I bought a Qlocom extender but that would not connect so I returned it to Amazon. I have now bought a TP link RE550 but I can't get that to work either. I have tried Tether, WPS and a Lan cable but when I find the extender in WiFi in my phone and try to connect it says Network not in Range..
I will ring Virgin media but I doubt they will help with a range extender they did not supply. Any ideas?
