[see attached for a tracerute] when i first signed up with aDSL, i did not get speed i am paying for, so i call at&t to have a check run to see what/where problem was. as it turns out, i am at end of a run, approx 3k20 feet of copper. :-( so instead of 138 kbps, i average around 86 kbps. fiber is in my future. -- peace out. tc.hago, g . *please reply "plain text" only.
