Not an easy thing to find out. I have a friendly ISP at work who knows
how to get into the BT wholesale system which is used for broadband
fault reporting. It tells you lots of interesting things about the ADSL
line which your router does not. Even when using that to try and work
out the speed of a new line before it goes in (just give it a phone
number) there is no way to get it spot on.
I have a lot of users in the middle of no where and just resetting the
router gets a different speed each time. One of the best indicators is
the downstream attenuation (might be that one or the line noise, it's
getting late). The BT rule of thumb in there system is if it's over 60db
then it's at the at the limit of broadband. I have a few at 65db+ and
it's *really* flakey. Best is around 45db.
Most ADSL which is 8mb+ is rate adaptive and it depends very much on how
many pigeons are sitting on the wire. Live near the exchange if you can
is the only way to get good broadband. It will be a *long* time before
BT upgrade the exchanges for the 21st project of theirs.
