    How do ISPs cripple the speed of their sub-512k services ?

    The reason I ask is that last week I set someone up with
    a Pipex 250k ADSL service. Download speeds from web
    sites and speed test utilities are typically 180k. I obtained
    some improvement by tweaking MTU and RWIN.

    Using Pipex's own 'internal' speed test utility I was getting
    220-230k before tweaking, now it's 260-270k !

    The very same router (AMX-68) and PC when connected to my own
    Pipex 512k service consistently reads 480k on the same tests.

    Diagnostics show d/s attenuation as 40dB, and no errors (my line is 63dB)

    All this leads me to believe that Pipex do something rather 'hamfisted'
    to reduce the speeds?

    I posted on this topic last week and another 250k
    user replied with similar experiences. Does anyone else have
    problems with their sub 512 ADSL services ?
