Re: Why I regret joining virgin media

When they do another re-pull, do get the power level checked again as you've been moved up to overcome some attenuation. DS should be between -3 dBmv & +6 dBmv; US should be between 35 dBmv and 50 dBmv. IMO 33 dBmv is OK (others disagree); Over 50 dBmv is usually OK but should be below 55 dBmv. I'm always suspicious of anything that has to push hard i.e. above 50 dBmv.

Upstream needs to be checked by refreshing the screen every 5 seconds to ensure it's stable within ½ dBmv.

Finally, there should be no uncorrectables after downloading data.
