Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Please tell me about the complete hardware and software context of your modem problem.
- for instance:
how you can tell it isn't hanging up
what computer it is in
whether the modem is a plug-in card or not (if it is a plug-in card then I would suggest reseating it while the computer is shut down.)
and so forth.
With that information, I will have several appropriate suggestions for the particular case.
