    Hi Guys,

    So far i'm very impressed with the speed and performance of my connection. But i've noticed lately that my connection has been a little flaky (slow and dropping on occassion)

    I've done some investigation and notice that i'm getting a lot of errors on the downstream in the logs. can anybody shed some light on if these figures are normal and if i should be contacting VM for support.

    DS Power closer to zero is expected. Not sure its bad enough to be significantly out of whack but if its a COMPAL then the big issue is pending a software fix.

    Oh Man i didn't expect such a reply.....kinda hoped for a Yea they are fine or nah something is a miss with your cable/connection.

    Will have to read up and understand what all that means.

    I do believe my router is a COMPAL one looking at the mac address so i'll wait and see what VM release if anything.

    Might have a look at the cabling also as its possible that i have a dodgy connection somewhere.

    Thank you for your response though, i like learning new things so i'll have a good read.
