I'm guessing that in you're ME partition, you may have limited the speed at which the modem can send packets. Have you tried going into you're Modem's settings in Control Panel?

Control Panel -> Modems -> Dialing Properties

Near the bottom, you'll see a pull-down-menu. Put this as high as it can. Worth a bash
