You are approximately 1.27km from the exchange (straight line distance).

Perversely, though, i can download at over 7.5 meg constantly, peaking at over 9 meg
(providing that its not peak time, of course)
I fact, i just did a download earlier today, when the storms were at their highest, and
got an above constant 7.5 - 8 meg.
The line has been rock solid for weeks now....never dropping
