ok i'm a telewest engineer just thought i'd add my 10cents:

10mbs modem models - motorola surfboard 5100, 5200
webstar EPC2100 V2
there are others but we dont install them anymore so if u've got an old one ask for a new one or just "accidentally" break it! then make sure the tech gives you one of those models. if they try to give you a webstar dpx100 they're crap anyways so just aviod them.

signal levels - '-15' downstream is within spec?!? are you mad?! -7 is the lowest you can go and expect a serivce! even then you'll lose it completely at peak times.
upstream levels - this ones important -you can get away with 56, but again like the downstream you'll lose service at peak times. anything under 50 and your laughing.
you can expect to lose 1-3dB at peak times on the down which means a similar upstream rise.

as for changing upstream channels it can help lower ur upstream, but wont help download speeds - the main problem is people downloading huuuuuuuuuuuuuuge vast mahooosive amounts of data all day all nite!
and also remember that our networks were instaled a while ago - anyone remember analogue Cable TV?? hmm?? so a network primarily designed for analogue then being upgrade to digi is gonna give you issues eventually! its plain ol' common sense.
Especially with the amount of data they cram down a bit of coax into your house now.
and those people who say "i kno the advert says 'upto 10meg' but a service that only reaches 5-6meg??" STOP THERE YOU'VE ANSWERED YOUR OWN FRIKKEN COMPLAINT! UPTO! not garunteed at all.
anyway thanks for reading.
