What have BT said about it ? Leaving may not fix your issue if its an actual line fault . First off try a quiet line test pull the front plate off the BT socket and attach your phone to the test socket in there dial 17070 choose option 2 . Listen carefully for noise or pops and clicks . If there is report a fault on the voice line this will receive quicker action than reporting a broadband fault . If your WiFi is not reaching rooms at the top or back of the house I would advise buying a few earthnet adapters a using that for PCs etc as for the phones , tablets , buy a few cheap WiFi repeaters and place them around the house they are cheap about 510 on eBay and run off a USB connection . <| sep |> But , vaccines cause autism . s
