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 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 seek 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 pressing the
Reset button at the back of your router for more than 6 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
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 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.
