What is Error 680: No Dial Tone And how do I fix it?
A. Error 680 is a result of your modem not detecting dial tone. This can be caused by the line being in-use, the phone line being either not plugged into the modem or being plugged into the wrong port, or in some cases the modem having been damaged. To fix this, check to make sure the phone line is plugged into the Line port of the modem and all phones in the house are on hook. If this doesnt resolve the issue, the modem may have been damaged and may need to be replaced. The dial-up modem is a single card within the PC that can be replaced quickly and cheaply.
