Gidday all,


I run a tech business from home, and for over a year now have been unsuccessfully trying to identify the reason for my stubbornly poor ADSL performance (no more than 2000Kbps, seemingly very poor performance with streaming media of any kind).


I run various servers over this connection and depend on this connection to collaborate with creative craftspeople here when I'm overseas. As things stand I'm less "weta", more "wait-er"!


My ISP is Orcon, I'm on their highest max/max plan. I have a central splitter installed.


Telecom were installing cabinets in my suburb late last year. According to the Chorus spreadsheet, my cabinet (PLM/G) was supposed to be cut over 1/1/10. I'm not sure if its active yet; certainly no improvement in my connection speed is so far evident.


I use a USR9108 as ADSL router, and its reporting I'm syncing ADSL2+. Here's what the router is reporting about ADSL stats:-

Additionally its BER test shows no errors.


My extremely unschooled impression of the table above is that there seems to be a lot more errors with upstream than down... is that a relevant issue? Related to attenuation maybe? Whats a likely physical cause?


Guys, I would be EXTREMELY grateful for any advice!
