The irony is though that depending how extensive the work is for the capacity upgrades, it might indirectly fix your problem anyways.

Hmm, you say you should experience disconnections... my Upstream is at 30.5dBmV during the day and night depending on the temperature outside. My downstream power is near perfect at 0 to -1 to 1 on all the different channels. Weird.

Say ever since I had my cable installed, they put a rather short coax cable in.. can I get an engineer to come fit a longer one?

And on the side check the power? XD

8 Days later on the VM forum and still no reply... Pretty frustrating...

have you tried 150/151 again? try going through BB support then if unsuccessful on getting a tech booked call again and press 5 for thinking of leaving and rant on an unstable connection, you being told your levels are out of range etc.

My power levels have gone up to-day. There was an outage and since coming back on instead of being QAM64 they are now QAM256. Presumably in connection with the speed doubling?

There's still no actual problems as I still get 30Mbits.

Should I phone up?

your down levels are high.. could prove to be unstable. its up to you, see how it goes or call 150/151 to book a tech to lower them.

Hmmm, ig is a tricky one. I wouldnt want to tempt fate and if it is working ok i would personally leave it. that being said, the ds power levels are out of spec for vm so if you rang up they would send someone round to fix it

After a polite but frustrated post on the forum about other people getting responses, a mod flagged it for review and I got a message asking me for dates to book an engineer..

Good stuff. Let us know how you get on
