How to Reset a Modem From a PC
Most broadband modems have a configuration utility that can be loaded from within a web browser. The utility can be used to monitor signal levels, obtain addresses, and retrieve error codes. In addition, many modems have the ability to be sent a reset request-packet from your PC. Depending on the type of modem, ISP, and service type the reset feature can actually cause the modem to request a new configuration. This can sometimes resolve connection issues.
Open your web browser. Practically any web browser will work.
Erase your homepage address from the address bar.

Look for a link or tab called "Administration, "or "Configuration."
Click on the "Reset" or "Restart" button.
