Chapter 5: Troubleshooting
If the router is not functioning properly, first check this chapter for simple troubleshooting before contacting the Help desk.
Problems starting up the router
Problem
Corrective Action
None of the LEDs are on when you turn on the router.
You have forgotten your
router login and/or password.
Check the connection between the adapter and the router. If the error persists, you may have a hardware problem. In this case you should contact 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 holding the Reset button on the back of your router for 6 – 8 seconds.
Problems with the WAN Interface
Problem
Corrective Action
Initialization of the PVC connection (“linesync”) failed.
Frequent loss of ADSL linesync (disconnections).
Ensure that the telephone cable is connected properly from the ADSL port to the wall jack. The ADSL LED on the front panel of the router should be on. Check that your VPI, VCI, encapsulation type and type of multiplexing settings 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.
Ensure that all other devices connected to the same telephone line as your router (e.g. telephones, fax machines, analogue modems) have a line filter connected between them and the wall socket, and ensure that all line filters are correctly installed and the right way around. Missing line filters or line filters installed the wrong way around can cause problems with your ADSL connection, including causing frequent disconnections.
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.
