The main bt phone box is downstairs and I want to use b/b upstairs. I've been told running extension cable upstairs is no good as adsl signal won't carry. Do I have to get the bt engineer in to do it properly or is there another way?
I DIDN`T GET A PHONE EXT. CABLE. I GOT A 25M DSL CABLE AND RAN THAT FROM THE BT CONNECTION BOX IN THE HALL DOWNSTAIRS. THA WAY I ONLY USED ONE FILTER. PLUS IF YOU USE PHONE EXTENSION CABLE, THEN DSL CABLE, I DO BELIEVE YOU WILL BE PRONE TO PROBLEMS
