Have you spoken to anyone else with VM service?

Yep, I'm ex-Telewest. I'm not even sure there is anybody else on my street who has VM broadband. I shall do some asking around, although I suspect a lot of people wouldn't have noticed anything amiss, other than things being a bit slower than usual. Thanks for the suggestion.

There are amplifiers every 100m and if they're working properly, he should have needed to move you up in the frame. If they're not working properly, that could be where the problem lies.

To be fair it could well be me mis-remembering the details of what I was told - this last issue was a couple of years ago. We had a number of engineers out and several attempts at solving it though and I'm absolutely positive some of them didn't know what they were doing because they told me conflicting things about the power levels I was seeing at the time. This was one of the things that prompted me to post here this time - so I stand a chance of spotting when I'm being fed a line.
We never had a single problem with our service in our previous house for the 4 years we had it. Since moving into this property its been one thing after another and they've all been a real sod to get sorted out. I'd just put it down to bad luck...

TV STB is currently showing the following:
SNR - 33.308dB
AGC Signal Level (whatever that is!) - 8dBmV
Return Power - 45dBmV
I also noticed a Timers section. I assume this is the same kind of thing as VM referred to seeing on my connection? (A cable STB is basically still a cable modem, isn't it?). The Timers section had a T1 count of 1 and a T4 count of 25. All other counters were zero.
Thanks again for taking the time to reply.
