A quick update. The engineer arrived 755 this morning, tested the line and said there's no problem with it. He said it could be that a neighbour reported the fault and it had already been fixed. Either way, happy with the speed we're getting now, 26703 downstream. He's left us his mobile number in case it happens again, said he's in the area today and tomorrow if needed.
Thanks for all your help. I've attached the current router stats, SNR looks a lot better than it was. Not sure if the errors are a problem, they only happen right after connecting and then the number stays the same.
Cheers
Ian
