Help me understand my up-stream speed

Question

Despite having excellent down-stream speed, I have been having problems with insufficient up-stream bandwidth for a long time. This causes me problems with a Vodafone Sure Signal to the point that I can't really use it for my mobile calls unless there is no other traffic on my broadband.
I have bounced between Vodafone support who tell me that I don't have enough up=stream bandwidth and I must speak to BT, and BT who tell me that my upstream speed is fine and there is nothing that can be done.
Until this weekend I though that my Broadband connection was typical with 448/7680 sync speeds. The BT speed tester doesn't show me my up-stream info. I'm not sure if it's because I'm a BT Vision customer, but instead it gives:

This weekend I helped my mother get a new broadband connection up and running and after the initial Home Hub 3 connection her speed test results were (printing to PDF initially mixed the data up):

This means that her download speed is approx half of mine, but her upstream is double !!!!
How is the up-stream speed determined, and more importantly how can I get my upstream speed to a more acceptable speed?

Answer 1

you are on adslmax and the max upstream connection is 448 whereas your mother is on 21cn adsl2 with an upstream of about 1000.  until your exchange is upgraded to 21CN you will not get a faster upload connection
