I don't fully follow the debate on these things, but isn't a large part

the provider? Not sure what difference cable makes.

It's contention that's the issue- how many users are using the wire
simultaneously. Adaptive rate ASDLMax shares the load, so when a lot of
people are using the equipment between the exchange and you, the speed
drops. I believe that the advertising standards authority are now about
to investigate the 'up to 8Mb' claims of the ISPs, because although
strictly speaking it's true, in practice it's very deceptive. I read
that the (very) vague guarantee was that you should get the equivalent
of 2Mbps. When it started, and not everybody had broadband, in SW London
I was getting 5.4Mbps with Demon ADSL. By the time I changed address, it
was down to 3.5Mbps at night, 1.8 in the daytime, occasionally down to
1.5Mbps. Now, still with Demon but on a different exchange, I'm getting
about 2Mbps in the day, 3.4Mbps at night. I can live with this. It's
inherent in the equipment and the protocol.

back in wales the contention is't much on a bad day it's 3 most you'll
get 5 tp 6.

my folks place gets about 1mb which my nokia 770 using my phone as
bluetooth modem can beat...

My son in law down the road switched to NTL cable. Contention doesn't
enter into it. From what he tells me he gets around 4.5Mbps day and
night. Fine, but I don't want to change my email address and the cable
companies tie you down to using them as ISP. Not worth it for me.

thats one reason i have allways used email not attached to a ISP, makes
telling the buggers you moving less of a pain.
