has been installed with a resource conflict. Uninstall the modem by
highlighting it and then clicking the
Remove button. You will be
asked if you are sure you wish to uninstall the device. Click OK . Next,
you need to free an IRQ for the modem. Double-click the Computer
icon at the top of the “Device Manager” screen. In the “Setting”
column, look for numbers between 3 and 15 that aren't listed. These
are IRQs available for use by the cable modem. If none are available,
choose a device to be removed or disabled. We recommend disabling
any serial or COM ports that are not in use. Once you have freed the
necessary IRQ, restart your computer and turn to the chapter titled
"Cable Modem Software Installation”.

"TCP/IP --> Dial-Up Adapter". Click the entry to highlight it and then
click

"Installed gateways:" field, click the numbers that appear in that field
and then click
Remove . Then click OK and click OK again. When
Windows asks if you want to restart your computer, click Yes . When
your computer restarts, try connecting again.
