Wi-Fi and home phone line

[Loz123]

I had fibre fitted on Friday and since it was done because the hub has been moved, the Wi-Fi connection in my living room is now 36 and My sky Glass TV keeps buffering.  In the kitchen, it's 120 and 140 In the room where the Hub  is Which is a bedroom so not so bothered about the connection being great there. I have now connected my phone to the hub like I was advised by the engineer And now I can't get incoming calls, but I can call out?? It's not helped by the fact you can't find a phone number where you can actually speak to someone about these issues.

Who were you with before ?

Does it say bt digital voice on the handset.

It doesn't say bt on the digital handset. I was with sky before for everything and I've just moved over to fibre still with them. The engineer showed me where to plug my phone in etc and had a dial tone so I thought it was working till today. If you ring it just beeps three times and that's it.
