Have you talked to Telstra Saturn to see if their cable connection is avaialble to you? They run their own cable connection sin some parts of chch (not mine unfortunately) and are very good and stable.

Thanks Shane, I wish I was able to get Telstra Cable. Unfortunately out of zone, and they have no short term expansion plans.

If you are on the Xtra go-large plan then you can expect variable performace. If you move to the Adventure plan you might get better results because it is not "traffic managed".
I chose the Pro plan to be not traffic managed but no difference as sharing with all other abusers.

PS I got to the bottom of my disconnection problems;
Don't run torrents on a wireless 802.11b connection to a DLink 604t!

I gotta admit I am still old school here and consider peer2peer and torrents abuse of precious bandwidth... not so much the technology or enabler, just the fact that you have a pile of pimply teens downloading GBs of games, illegals songs and pr0n 'because they can' without a care that it impacts dedicated connections.
I ended up speaking with one of the Advanced Response team for Xtra and as predicted it is purely a capacity issue on the backhaul, as this is a high takeup exchange.
Xtra have scheduled me to move to newer equipment tomorrow with fewer users, however cannot guarantee, but worth a shot. Agreed that come 4pm on the dot every day we hit the wall. 1189ms pings today and 173kbs average for a 1mb file {slow slow nothing nothing slow lightning slow slow}.
