Chapter 6

The Router Is Not Functional

1. Check to see that the power LED is green and the network cables are installed correctly.
Refer to the quick start guide for more details.
2. Check to see that the LAN and Status LEDs are green.
3. Check the settings on your PC. Again, refer to the quick start guide for more details
4. Check the router's settings.
5. From your PC, can you ping the router? Assuming that the router has DHCP enabled and
your PC is on the same subnet as the router, you should be able to ping the router.
6. Can you ping the WAN? Your ISP should have provided the IP address of their server. If you
can ping the router and your protocols are configured correctly, you should be able to ping
the ISP's network. If you cannot ping the ISP's network, make sure you are using the correct
protocols with the correct VPI/VCI values.
7. Make sure NAT is enabled if you are using private addresses on the LAN ports.

You Cannot Connect to the Router

1. Check to see that the power LED is green and that the network cables are installed correctly.
If the LED is off, make sure the router is turned on. If the LED is red, please contact your
ISP.
2. Check the Ethernet network cable is plugged in correctly. If the LAN LED does not turn
green when the Ethernet cable is connected to the router, check the cable.
3. Make sure you have connected the Ethernet port to the PC.
4. Make sure that your PC and the router are on the same network segment. The router's
default IP address is 192.168.1.1. If you are running a Windows-based PC, type ipconfig /all
(or winipcfg /all on Windows 95, 98, or ME) at a command prompt to determine the IP
address of your network adapter. Make sure that it is within the same 192.168.1.x subnet.
Your PC's subnet mask must match the router's subnet mask. The router has a default
subnet mask of 255.255.255.0.
5. If the router is in Bridge mode, you may need to set your PC to a fixed IP address within the
same subnet as the modem (i.e. 192.168.1.2)

The DSL LED Continues to Blink

This means that the DSL line is trying to train but for some reason it cannot establish a valid
connection. The likely cause of this is that you are too far away from the central office. Contact
your DSL service provider for further assistance.
