Troubleshooting Internal Modems

Step Six:

With your modem now re-installed with fresh drivers on correctly setup Com Ports, click on the Diagnostics tab in the Modem Properties screen. You should have two Com Ports listed: Com 1 and Com 2 (sometimes it will be another instead of Com 2).

Com 1 is the Com Port we enabled in the BIOS earlier. Your modem should not be listed against this as it's for external devices. Your other Com Port should have the modem listed next to it. The second Com Port is a VIRTUAL Com Port. I like to think of it as the socket you plug your modem cable into in your modem. This gives it a physical presence. Click on the Com Port with your modem listed next to it and go for More Info again. If you get the AT commands then your modem is installed and setup correctly. If you get any error messages there is still a problem. If all is OK, try to dial out with your modem again.

Step Seven:

If you receive an error message, it is normally "Port already Open". In this case, hold down CRTL + ALT + DEL once and you should receive the Task Manager screen. End Task all applications one at a time except for Explorer and Systray. (Click on a program, click End Task, and hold CTRL + ALT + DEL again, repeat.)

Once done, repeat Step Six.

The "Port already Open" error message normally relates to a Windows program running in the background "hogging" the modem port. End-tasking all programs except for Explorer and System Tray negates this possibility. If your modem will More Info without any error messages after ending these programs, it
will be a program in the background. Identify which one it is (normally FAX software) and remove it from your startup group.


If you still get "Port already Open", chances are you have a fault with your Modem.

If your error message is "No Dial Tone" when trying to dial out, check your dialing properties and make sure they are correct for your location (click on the Dialing Properties button on the General page of Modem Properties). If you still receive no dial tone, chances are you have a faulty modem.

If you hear your modem dialing out, but you recieve an error when trying to establish a connection, give your Internet Service Provider a ring. It may be a problem with their software or dial-up connection. They will have the information to correct it. You may have to re-install "Dial-Up Networking". This part of Windows contains all the software and communication protocols for allowing computers to talk together.

To re-install Dial-up Networking:

Enter Control Panel and double click the Add Remove Programs Icon. Click on the Windows Setup tab. After a few seconds you will see the list of Windows components currently installed. Click on Communications and click the Details button.

You will now see a list of the Communications components. Click on the tick next to Dial-up Netorking to remove it and click OK and APPLY. This will remove Dial-Up Networking.

Once done, you may be prompted to Reboot. If so, let Windows restart your PC and return here again. Once the components have been removed, go and put the tick back next to Dial-up Networking. Click OK and APPLY again. You may be prompted to insert your Windows CD-ROM at this stage. When all has finished copying, reboot your PC again (it will probably prompt you).

Dial-up Networking has now be re-installed. Re-install your Internet Service Provider's software.
