i have a acer aspire one model#d250-1326, which has windows xp; the internet explorer wasn't working properly so the computer need restoring. however, now the network controller is not working. it has a exclamation point next to it and says that the driver is not installed. i have tried for days to fix it, but to no avail. the computer says there are no drivers on there for this device. i can't get on the internet to find a fix from this computer, but i have access to another computer. please help!
