However, please note that all has been working fine for years and years. I think it is highly unlikely that my internal wiring has suddenly gone dodgy.
But that applies to the telephone line, DSLAM etc as well!
Unlike previous suggestions I wouldnt expect packet loss to be caused by line problems etc - I would seriously worry about the Router and after that the exchange equipment.
If TT have arranged for an OR visit I don't thing they are going to find anything wrong which will generate a charge (to TT) which they may try to recover from you!
Have they warned about the possibility of being charged?
EDIT: Read the thread starter and TT have mentioned a charge of £50

. This is less than OpenReach would charge though.
