Unplug all connection to modem. Then reconnect everything. This may clean a dirty contact.
Use modem on another computer. If it works fine on another computer then it's the computer software causing the problem. Un-install and re-install modem software. It maybe the OS and not the modem software, this may require a re-install of OS to fix (not a job for a novice).
Sometime the ISP connection is the problem. Make sure by calling ISP that they are not having the problem. I have seen error messages like this when it was the ISP not providing a good signal.
The modem maybe going bad. Works for a few minutes and as the failing part hates up the modem shut down.
Hope this helps.
I have microtek 56k external dialup modem. When I connect to internet, after few seconds, incoming of data bytes stops. When I disconnect and tries to reconnect an Error come ?ERROR OPENING PORT MODEM OR OTHER CONNECTING DEVICE FAILURE?.
