are useful aides for finding possible problem causes.
10.1.1 Power LED
The
PWR LED
on the front panel does not light up.
STEPS
CORRECTIVE ACTION
1
Make sure that the power adaptor is connected to the router and plugged in to an appropriate
power source. Use only the supplied power adaptor.
2
Check that the router and the power source are both turned on and the router is receiving
sufficient power.
3
Turn the router off and on.
4
If the error persists, you may have a hardware problem. In this case, you should contact your
vendor.
10.1.2 LAN LED
The
LAN LED
on the front panel does not light up.
STEPS
CORRECTIVE ACTION
1
Check the Ethernet cable connections between your router and the computer or hub.

The
ADSL LED
on the front panel does not light up.
STEPS
CORRECTIVE ACTION
1
Check the telephone wire and connections between the router ADSL port and the wall jack.
2
Make sure that the telephone company has checked your phone line and set it up for ADSL
service.

Reset your ADSL line to reinitialize your link to the DSLAM.
4
If these steps fail to correct the problem, contact your local distributor for assistance.

3
Check that you have enabled web service access. If you have configured a secured client IP
address, your computer’s IP address must match it. Refer to the chapter on remote management
for details.
4
For WAN access, you must configure remote management to allow server access from the
WAN (or all).
5
Your computer’s and the router’s IP addresses must be on the same subnet for LAN access.
6
If you changed the router’s LAN IP address, then enter the new one as the URL.
7
Remove any filters in LAN or WAN that block web service.
The web Interface does not display properly.
STEPS
CORRECTIVE ACTION
1
Make sure you are using Internet Explorer 5.0 and later versions.
2
Delete the temporary web files and log in again.
In Internet Explorer, click
Tools
,
Internet Options
and then click the
Delete Files ...
button.
When a
Delete Files
window displays, select
Delete all offline content
and click
OK
. (Steps
may vary depending on the version of your Internet browser.)
10.3 Problems with the Login Username and Password
I forgot my login username and/or password.
STEPS
CORRECTIVE ACTION
1
If you have changed the password and have now forgotten it, you will need to upload the default
configuration file. This will erase all custom configurations and restore all of the factory
defaults including the password.
2
Press the
RESET
button for five seconds. When the
ADSL
LED begins to blink, the defaults
have been restored and the router restarts.
3
The default username is “
admin
”. The default password is “
admin
”. The
Password
and
Username
fields are case-sensitive. Make sure that you enter the correct password and
username using the proper casing.
4
It is highly recommended to change the default username and password. Make sure you store
the username and password in a save place.
10.4 Problems with LAN Interface
I cannot access the router from the LAN or ping any computer on the LAN.
STEPS
CORRECTIVE ACTION
1
Check the Ethernet LEDs on the front panel. A LAN 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.
2
Make sure that the IP address and the subnet mask is consistent between the router and the
workstation.
10.5 Problems with WAN Interface
Initialization of the ADSL connection failed.
STEPS
CORRECTIVE ACTION
1
Check the cable connections between the ADSL port and the wall jack. The ADSL LED on the
front panel of the router should be on.
2
Check that your VPI, VCI, type of encapsulation and type of multiplexing settings are the same
as what you collected from your ISP.
3
Restart the router. If you still have problems, you may need to verify your VPI, VCI, type of
encapsulation and type of multiplexing settings with the ISP.
I cannot get a WAN IP address from the ISP.
STEPS
CORRECTIVE ACTION
1
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 your are using a Central Splitter or Central Filter installed by the qualified
and licensed electrician), and ensure that all line filters are correctly installed and right way
around.
2
Missing line filters or line filters installed the wrong way around can cause problems with your
ADSL connection, including causing frequent disconnects.
Frequent loss of ADSL line sync (disconnections).
STEPS
CORRECTIVE ACTION
1
The ISP provides the WAN IP address after authenticating you. Authentication may be through
