UPDATE - Engineer came yesterday...did some tests and replaced faceplate in living room with a faceplate that has 2 sockets(internet and phone) and now broadband and work together in harmony!! Just got to wait for next bill and see if they've charged me.
Thanks to everyone for help...will rep now.
I'm with Sky for TV, Phone and Broadband. I recently had carpets fitted and had to move all stuff out of living room. When i reconnected my equipment, everything seemed OK except for the internet. The problem I have is that my internet only works when i'm using the phone. As soon as i terminate the call, the internet stops working. The phone i have is a Binatone Zest Plus Telephone and Answer Machine - Twin (see link in first post). I have called Sky and carried out various tests, they have sent new router (which changed nothing). I have checked behind all four sockets in my home and none have a test socket. They were sending a BT engineer out today (obviously never turned up due to snow).
Broadband worked fine - unplugged for carpet fitting - plugged back in following day - no internet connection unless i'm actually using the landline or i have unplugged the phone from the splitter.
Have tried new router, various splitters in main socket (also had splitters in other sockets, despite none of them being in use).
Just wondering if anyone has any suggestions?
