Troubleshooting
If the Router is not functioning properly, you can refer first to this chapter for simple troubleshooting
before contacting your service provider. This could save you time and effort but if the symptoms
persist, then consult your service provider.
Problems Starting Up the TW-EA1000
Problem
Corrective Action
None of the LEDs are on
when you turn on the
TW-EA1000.
Check the connection between the adapter and the TW-
EA1000. If the error persists, you may have a hardware
problem. In this case you should contact technical support.
Problems with the WAN Interface
Problem
Corrective Action
Initialization of the PVC
connection failed.
Ensure that the cable is connected properly from the ADSL
port to the wall jack. The ADSL LED on the front panel of
the TW-EA1000 should be on. Check that your VPI, VCI,
type of encapsulation and type of multiplexing settings are
the same as what you collected from your telephone company
and ISP. Reboot the TW-EA1000. If you still have problems,
you may need to verify these variables with the telephone
company and/or ISP.
Problems with the LAN Interface
Problem
Corrective Action
Check the Ethernet LEDs on the front panel. The LED should
be on for a port that has a station connected. If it is off, check
the cables between your TW-EA1000 and the station. Make
sure you have
uninstalled
any software firewall.
Can’t ping any station on
the LAN.
Verify that the IP address and the subnet mask are consistent
between the TW-EA1000 and the workstations.
