  • Reboot.


  • Make sure that no other programs are using your modem. Fax software, Supervoice, etc...

  • AOL can also cause this issue. If AOL was or is installed try deleting the AOL Adapters in the Network Control Panel then reboot and reinstall the Dialup Adapter.


  • Is the modem using an initialization string? If so, try removing it and replacing with: ATZ


  • Does the user have Quicken 2000? If so, try disabling the Quicken Download Manager, found on this page. A Dell article on this issue can be found here.


  • Try uninstalling and reinstalling the modem.
