We had the BT engineer install a new master socket with the adsl filter built in so the broadband signal is stopped before it reaches any other extensions (which where also tested and found to be ok).
The router is in my hall on a table with nothing else in the hall what so ever. The nearest thing to it or the line would be a TV around 10ft away and behind a brick wall. This also includes central heating, the router is probably furthest away from any pipes or pumps that it could possibly be, in the whole house.
The BT engineer tested the line and looked for tree rub and said he didn't find anything to suggest we would have any problems.
It would be good if there where more tests that could possibly be done to maybe narrow down this problem.
