If you have call waiting on your phone line and somebody calls you while you're using the Internet, most likely your modem will disconnect you from the Internet. This is because of the call waiting tones that alert you to a waiting call. Those call waiting tones temporarily interrupt the carrier tones the modems use to verify each other. Even though the tones last for only a fraction of a second, that is enough to make a modem think that the other modem has hung up, so the connection is terminated. If you have call waiting, you can temporarily shut it off by adding *70 to the beginning of your phone number.

Tip: The next time you go to connect, go to "Dial Properties" on the connect box, and choose the option for call waiting.
