Basic Troubleshooting
Steps
1. Make sure that your phone cord is properly connected. Remove the
phone cord from the modem and wall jacks. Reinsert the cord securely in
the wall jack and the modem’s jack labelled . Use the phone cord
included with your modem, if possible.
2. Make sure that your 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 connector edge, which may be gold or
black. See the Installation Guide that came with your modem for
instructions more specific to your modem.
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 2000 If you set your modem’s jumpers to Plug-and-Play
mode, Windows should locate a free IRQ, if one exists, for your modem
to use.
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 Hardware tab. In the Device Manager section,
click Device Manager . From the View menu, select Resources by type .
Click Interrupt Request (IRQ) . 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.
Locate your modem in the list of devices. If a yellow exclamation point
appears over the modem’s description, your modem is in conflict with
another device. Either your modem or the other device will have to be
reinstalled to another IRQ in order to resolve your conflict.
If a usable, free IRQ does not exist, you may need to remove, disable, or
relocate another device. Refer to that device’s documentation for more
information about removing, disabling, or relocating it.
