INTERNAL ISA MODEMS
Basic Troubleshooting Steps
1. Make sure that your phone cord is properly connected. Remove the phone cord from the modem and wall jacks. Clean any dirt or
corrosion from the cord and jacks. Reinsert the cord securely in the wall jack and the modem’s
jack. Use the phone cord included
with your modem, if possible.
2. Make sure that your internal modem is physically installed correctly in your computer. With your computer off, remove the modem
and reinstall it in another slot if possible. When the modem is installed correctly, you will no longer see any part of the gold edge. See
the Installation Guide that came with your modem for complete instructions.
PROBLEM: My computer isn’t recognizing my modem.
Possible solution:
You may be using an IRQ that is already in use. To work properly, your modem needs to be assigned to a free IRQ.
Windows 95/98
If you set your modem’s jumpers to Plug-and-Play mode, Windows should locate a free IRQ, if one exists, for your use by your
modem. See the “Windows NT Users” section on the other side of this Guide for more information, as the installation using
jumper shunts is similar for Windows NT, 95, and 98.
If Plug-and-Play fails to install the modem, you need to determine IRQ availability. Right-click the My Computer icon on your
desktop. Click Properties, and then the Device Manager tab. Double-click the Computer icon at the top of the device list. You
will now see a listing of your system’s IRQs and the devices to which they are assigned. If an IRQ is not present in this list, it
indicates that Windows is not currently using it and the IRQ is considered available.
