Hello,

The maximum speed my router connects to my exchange at is around 2000kbps. I always thought that this was due to the fact i must be about 4.5KM away from my exchange.

Recently, the speed at which my upload connects to my exchange at has increase and now connects at 832kbps.

My questions are these:

If my upload connects at full speed, does this mean im closer than I thought to my exchange and in such a case, the old lines within my house could be restricting my download connection speed?

Is there an ADSL upload graph that shows upload speeds compared to distance from an exchange? I've seen a download graph before.

Thanks for any suggestions/comments.

Many factors determine the speed your ADSL modem will train to the DSLAM at. Distance (as you know), congestion in your area, electrical properties of the copper and etc. ALOT of ADSL speed issues can be traced to poor wiring from the demarc point to your telephone socket in the wall, especially if you have an old house that was previously wired for the old NZPO phone system :-)

Is there an ADSL upload graph that shows upload speeds compared to distance from an exchange? I've seen a download graph before.

the minimum upload line-speed is about 64k *I think* the maximum is ~800kbps so you are lucky!

PS any benefits of having more upstream may be negated by the fact Telecom sell only 128k and 512k upstream and D-links.

If the maximum upload is around 800kbps and i'm getting 832kbps, what distance from the exchange would you estimate i was?

And if I am close enough to get 832kbps upload, then why can't i get more than 2100kbps download?

Thanks for the link too.
