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.
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.
You have forgotten your
router
login and/or
password.
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. 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.
Frequent loss of ADSL
linesync
(disconnections). 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 Corrective Action
Can’t ping any PCs on
the LAN. 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.
Most problems can be solved by referring to the Troubleshooting section in the User’s Manual. If you
