Q. I have a two-line phone, and when one line is busy, the call jumps to the second line. But when my partner is speaking to someone and I’m on the Internet, every call that comes in triggers call-waiting and that breaks my Internet connection. Short of adding more lines, what can I do about it?
A. Every telephone system has a call-waiting disabling code, which can be added to the phone number you use to connect to your Internet provider. Ask your phone company for its code. For example, if it’s #70, program your Internet dial-up number to begin with #70—such as #70-1-555-555-5555.
