5.2 Problems with the Web Interface
I cannot access the web Interface.
STEPS
CORRECTIVE ACTION
1
Make sure you are using the correct IP address of the router. Check the IP address of
the router.
2
Make sure that there is not a console session running.
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.

5.3 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
DEFAULT
button for five seconds, and then release it. When the
ADSL
LED
begins to blink, the defaults have been restored and the router restarts.

The default username is “
admin
”. The default password is “
trendchip
”. 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.
5.4 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.
5.5 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 telephone company and 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 telephone company and 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
Page 79 / 80
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 the user name and password, the MAC address or the host name.

The username and password apply to PPPoE and PPoA encapsulation only. Make sure
that you have entered the correct
Service Type
