Chapter 5: Troubleshooting
If the router is not functioning properly, first check this chapter for simple troubleshooting before contacting your service provider.
Problems starting up the router
Problem
None of the LEDs are on when you turn on the router.
You have forgotten
your router login and/or password.
Corrective Action
Check the connection between the adapter and the router. If the error persists, you may have a hardware problem. In this case you should seek technical support.
Try the default login and password, refer to Chapter 3. If this fails, you can restore your router to its factory settings by pressing the Reset button at the back of your router for more than 6 seconds.
Problems with the WAN Interface
Problem
Initialization of the
PVC connection (“linesync”) failed.
Corrective Action
Ensure that the telephone cable is connected properly from the SHDSL port to the wall jack. The SHDSL LED on the front panel of the router should be on. Check that your VPI, VCI, encapsulation type and the multiplexing settings type are the same as those provided by your ISP. Reboot the router. If you still have problems, you may need to verify these settings with your ISP.
Problems with the LAN Interface
Problem
Can’t ping any PCs on the LAN.
Corrective Action
Check the Ethernet LEDs on the front panel. The LED should be on for a port that has a PC connected. If it is off, check the cables between your router and the PC. Make sure you have uninstalled any software firewall for troubleshooting.
Verify that the IP address and the subnet mask are consistent between the router and the workstations.
