I've been using the laptop since Christmas with no problems at all, then suddenly, one day it stopped working. Any attempts to connect to the internet using dial-up result in a "No dial tone" Error. According to the device manager, the modem is working correctly. The troubleshooter was unable to solve my problem. It's not because of my phone lines or anything, I'm connected on the same phone jack on a different computer. Tried contacting my internet provider, no help at all. Anyone experience anything like this before?
