    I had a 1.1 line which worked ok without performance problems. After a month
    it became very very slow. It was downloading at around 10kB/sec. I reported
    it to my ISP who logged a fault with BT. About a week later it was running
    at 80-90 kB/sec so I thought good they have fixed it. This lasted for 2-3
    hours then went back to being 10kB/sec.

    After a few more days my linespeed went to an indicated 576kbps. I am now
    getting about 30-40kB/sec download on my line which is supposed to be 1gb. A
    week after the linespeed was reduced I got a letter from my ISP saying
    congratulations they had upgraded my line to 1.1 OK however it isn't and the
    rate is not brilliant for a 576kbps line either.

    I just rang my ISP and was told that my speed has been halved by BT as I am
    too far from their exchange. I'm not, I am within the distance. It was
    working at the right speed originally and I reassure you that I have not
    picked my house up and moved it !

    My ISP say that they have to go by BTs comment that its too far away. What
    do I do as it was running at the right speed for a while so it cannot be too
    far away ???

  2. always a problem if you complain about something BT may opt to reduce
    the speed to increase the reliability.

    You need to find out what the line attenuation and SNR margin are on
    the current speed, this will give you a clue if going for 1M makes
    sense. If the margin is more than 16 dB and the attenuation less than
    60 dB you could have a go at getting a speed increase.

    Is your exchange congested, none of the speeds are very good. Check
    the VP status at http://usertools.plus.net/exchanges

    hiya Phil,

    the VP was red when I had problems... when it went very good it was
    'upgraded' when they downloaded the linespeed it decreased. I suspect
    there's no problem here but there is at the xchange.... but how do you prove
    it ?

  4. thinking a bit harder, as a Virgin customer you may be on "Datastream"
    and prone to NTLs own capacity management issues, rather than the
    exchange as a whole. To find out you have to try to log in with the
    [email protected]_domain login - this will fail if its datastream and
    allow access to a single page if its IPstream. (note there are _
    characters in there, not spaces)

    If it is datastream just chafe away at Virgin / NTL if its
    persistently slow. If its IPstream the plusnet status thingy will tell
    you what's what.

    good luck

    I know I am DataStream, BT have confirmed it. also you suggest a test, I've
    done it and that says so too.
