It is ridiculous.. Sorry jid but this has been going round and round in circles for over 3 months now, and Tiscali keep messing around with the profiles as they are doing arent doing jack all for your line. Its too unsteady because there is an underlying problem somewhere between the exchange and your home.
You should have a good line and you should be able to sync at the full 8Mb.. but you cant because of the SNR problem which several people have confirmed looks like a fault on the actual line which can only be fixed by a BT engineer.
Tiscali messing around with profiles aint going to do nothing until the underlying problem is fixed.
All the messing with profiles is doing is putting a sticky plaster over a leaky pipe.
