Chapter 6: Troubleshooting 
This appendix suggests solutions for problems you may encounter in installing or using your ADSL Router, 
and provides instructions for using several IP utilities to diagnose problems. 
Contact Customer Support if these suggestions do not resolve the problem. 
Problem 
Troubleshooting Suggestion 
LEDs 
Power LED does not illuminate 
after product is turned on. 
Verify that you are using the power cable provided with the device and 
that it is securely connected to the ADSL Router and a wall 
socket/power strip. 
LINK WAN LED does not illuminate 
after phone cable is attached. 
Verify that a standard telephone cable is securely connected to the 
ADSL port and your wall phone jack. Wait 30 seconds to allow the 
device to negotiate a connection with your ISP. 
LINK LAN LED does not illuminate 
after Ethernet cable is attached. 
Verify that the Ethernet cable is securely connected to your LAN hub or 
PC and to the ADSL Router. Make sure the PC and/or hub is turned on. 
Verify that you are using correct cable. 
DIAG LED stays illuminated after 
turning the device on. 
The DIAG LED should turn off after about 10-15 seconds. If it does not, 
turn off the ADSL Router, wait 10 seconds, and then turn it back on.   
Internet Access 
PC cannot access Internet 
Use the ping utility to check whether your PC can communicate with 
the ADSL Router’s LAN IP address (by default 192.168.1.1). If it cannot, 
check the Ethernet cabling.   
If you statically assigned a private IP address to the computer, (not a 
registered public address), verify the following: 
• 
Check that the gateway IP address on the computer is your public IP 
address. If it is not, correct the address or configure the PC to 
receive IP information automatically. 
• 
Verify with your ISP that the DNS server specified for the PC is valid. 
Correct the address or configure the PC to receive this information 
automatically. 
• 
Verify that a NAT rule has been defined on the ADSL Router to 
translate the private address to your public IP address. 
PCs cannot display Web pages on 
the Internet. 
Verify that the DNS server specified on the PCs is correct for your ISP. 
You can use the ping utility to test connectivity with your ISP’s DNS 
server. 
Configuration Manager Program 
You forgot/lost your Configuration 
Manager username or password. 
You can reset the device to the default configuration by pressing the 
Reset button for 3 times on the back panel of the device (using a 
pointed object such as a paper clip). Then, type the default username 
and password admin/admin. 
WARNING: Resetting the device removes any custom settings and 
returns all settings to their default values.
