i just re-installed windows on my toshiba satellite that i've had for a few years (virus problem), and now i get disconnected from the wireless internet whenever i switch to battery power. there are no problems on AC power, and it was working fine before the re-install. i've checked the driver and made sure that it doesn't get turned off to save power under the power management tab of the intel pro/wireless network driver window. also, i checked to see if i have an additional toshiba power management utility that could be turning it off, and it appears i don't. any ideas what it could be?
