"It's still supposed to be 1.5 M down and 384 kb up and has been until a couple of days ago. ... the minute I start utorrent, or any other bittorrent client, I cannot achieve over 175kb download and about 35kb upload." Sounds like you're confusing bits and BYTES as well as don't realize you'd been using ComCast's SpeedBoost heavily. 1.5 megabits/second down really will only achieve about 175 KiloBYTES/second download speed at best. The upload may be a little crippled...384 kilobits/second should be able to achieve ~40 KiloBYTES/second upload speed. As far as I know, ComCast doesn't offer a specific speed tier that gives 1.5 MegaBYTES/second and 384 KiloBYTES/second. And their "ordinary"/lower speed tier even in their fastest areas generally is slower than that at least on the upload side. I've only got 6 mbit/sec down and 1 mbit/sec up on the "ordinary" speed tier. But SpeedBoost can briefly do crazy things to my download and upload speeds: http://img683.imageshack.us/img683/9625/ut22ulburstvsdlspeed.png ComCast's DOCSIS 2.0 SpeedBoost in uTorrent v2.0.4 on Nov.5, 2010: http://img251.imageshack.us/img251/1228/ut22comcastdocsis20spee.png
