Hi, I'm Simon.I've been living at my girlfriends place off and on for a while.  They've always been with telecom(it was payed for by her dads work, under a work account).  They have always got speeds of around 400kb/s, I assumed that this was a cap on the work account, or that their line was crap.  Anyway, her dad is not with them anymore and have switched to a plan they pay for, for the first few days, I was stoked, we where getting speed tests up and over 6500kb/s sometimes eve 7000kb/s.  Unfortunatly, it's crashed back down to 400/500kb/s.  I've talked to telecom, turned my modem off and on so much my finger is bleeding. I've tried replaced filters and cords.
I've now changed everything back to how it was before, because everything else I did would make it go slower and slower.Does anyone have any idea why we would get such high speeds for the first 4 or 5 days?  Even they guy at telecom said we should be getting faster speeds, which in my experiance is strange as they usually tell you that it's your modem or line or some crap.
Is there anything I can do, or should I just commit to having crap internet.

We've got a speedtouch 610 and am on the Total Home-BB Adventure  plan.We're living in Hamilton, about 1k from center city.
