Troubleshooting

— Make sure the LAN port LED is on. If the LED is off, follow the instructions in

“LAN

or WAN Port LEDs Not On

” on

page 7-2

.

— Check that the corresponding Link LEDs are on for your network interface card and

for the hub ports (if any) that are connected to your workstation and router.

Wrong network configuration

— Verify that the Ethernet card driver software and TCP/IP software are both installed

and configured on your PC or workstation.

— Verify that the IP address for your router and your workstation are correct and that the

addresses are on the same subnet.

Testing the Path from Your PC to a Remote Device

After verifying that the LAN path works correctly, test the path from your PC to a remote device.
From the Windows run menu, type:

PING -n 10

<IP address>

where <IP address> is the IP address of a remote device such as your ISP’s DNS server.

If the path is functioning correctly, replies as in the previous section are displayed. If you do not
receive replies:

— Check that your PC has the IP address of your router listed as the default gateway. If the IP

configuration of your PC is assigned by DHCP, this information will not be visible in your
PC’s Network Control Panel. Verify that the IP address of the router is listed as the default
gateway as described in

“Verifying TCP/IP Properties“ on page C-6

.

— Check to see that the network address of your PC (the portion of the IP address specified

by the netmask) is different from the network address of the remote device.

— Check that your cable or DSL modem is connected and functioning.

— If your ISP assigned a host name to your PC, enter that host name as the Account Name in

the Basic Settings menu.

— Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many

broadband ISPs restrict access by only allowing traffic from the MAC address of your
broadband modem, but some ISPs additionally restrict access to the MAC address of a
single PC connected to that modem. If this is the case, you must configure your router to
“clone” or “spoof” the MAC address from the authorized PC. Refer to

“Manually

Configuring Your Internet Connection“ on page 2-17
