PROBLEM CORRECTIVE ACTION
Check the 10M/100M LEDs on the front panel. One of these LEDs
should be on. If they are both off, check the cables between your
Prestige and hub, or the station. Cannot ping any workstation on
the LAN.
Verify that the IP address and the subnet mask are consistent
between the Prestige and the workstations.
9.4 Problems With Internet Access
Table 9-4 Troubleshooting Problems With Internet Service
PROBLEM CORRECTIVE ACTION
Check all the connections. Make sure that the cable line is securely
connected to the cable jack on the back of the modem. Verify that
the RJ-45 cable is securely plugged into both the modem and the
computer. If all connections are made properly, all the LEDs should
be functioning properly.
Check your TCP/IP parameters and verify that you have installed
TCP/IP properly. If the problem persists, call your cable service
provider to verify that their service is two-way and DOCSIS-
compliant.
Cannot access e-mail or Internet
Service.
Check with your service provider to see if your account has been
activated.
All of the LEDs look right, but I still
cannot access the Internet. If the LEDs are right, then your cable router is operating properly.
Try shutting down, powering off your computer and then turning it
on again. This will cause your computer to re-establish
communications.
Check your TCP/IP parameters and verify that you have installed
TCP/IP properly.
