VoIP/(802.11g) ADSL2+ Firewall Router

Chapter 5: Troubleshooting

If the router is not functioning properly, first check this chapter for simple troubleshooting before

contacting your service provider or Billion support.

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 more than 6 seconds.

Caution: After pressing the RESET button for more than 6 seconds, to be sure

you power cycle the device again.

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

GE. 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 (unless you are using a

Central Splitter or Central Filter installed by a qualified and licensed

electrician), 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.
