I'm on the same as SimpleSimon
cpc3-pete4-0-0-custXXX.pete.cable.ntl.com
My download speeds are also really flakey. Ranging anywhere from 5mb to 10mb, but after midnight they are usually a lot better, 15mb upwards.
My modem power levels are fine, netstat -a is fine. Tracert's to bbc show some dropped hops now and again. I'm currently in the process of contacting VM support via their newsgroups, they've said there's no utlilization problems on the UBR so far, will have to wait and see what they say about my tracert responses.
Will keep you posted.
EDIT:
Hi
These results are a bit unusual.
From tests here the UBR is not over utilised or have any network related
issues that we can detect here.
Your signal levels and power levels are fine and your cable modem is one of
the newer ones.
Reverse tracerts to your computer do not show any issues

(next hop is firewalled).
If it is an issue its not with the ubr.
What time frame are we looking at that you are seeing these results?
Say if we arranged a technician to come and visit (say a 4pm to 7pm slot) do
you think you can replicate this issue for him?
