I became an Infinity customer in January this year. Completely trouble free until a couple of days ago when I started to notice broadband drop-out (HH2 with blue light turning to red). OK for a few minutes after reset but then off again. This was late in the day so phoned BT the following morning. Call centre noted fault and gave me a reference. received text message that fault was being traced - also got email to that effect (which, of course, I couldn't know at the time).
To my surprise an engineer appeared about three hours after the call, performed on site diagnostics went out to the FTTC cabinet returned to say that 'a couple of crimps were loose'. He performed the diagnostics again and then went to the outside junction box via a hole in the pavement. here he cleaned the various wires and replaced several connection pieces. He then performed diagnostics again, telephoned the centre(?) and reported that all was OK at that end. As he was talking he reconnected the openreach router to the PC and wall socket when the DSL light showed nothing - the router had gone phut as he talked. He replaced the router there and then. We remade all connections, synced and all has been well since. This chap was at my house for about two hours, pleasant, courteous and extremely capable. I am deeply impressed.
