thank for you information brink, but this didn't solve my problem unfortunately. When i'm on battery power my laptop connects to my external 56k modem good, with a good download speed, but as soon as I plug in the ac power cord my connection drops to crap. I tried to trick my modem by connecting to the internet while on battery power, thus achieving at least 40K connect speed, but as soon as i plug in the power cord, my download goes from about 8kbps to 2Kbps or less. Very strange. I'm thinking it is something to do with the modem being external running through a USB port for some reason, but i have tried all 3 USB ports on my laptop and they all give me the same issue.
