I've recently moved to Northcote, N-Shore Auckland and all I can say about Telecom so far is ABYSMAL!!!
My line syncs at around approximately 20Mbps, however.... most of the day the link is down and the Internet doesn't work.
I've tried all 5 phone points in the house, differnet filters and I am now on adsl modem number 3 - same problem.
I find that the line speed does vary, one minute its maximum attainable rate is 21500mbps... then its down to around 18400mbps...
Thoughts anyone? On the odd day it works fine without issue.
