Note:
●
Supply the
Service name
parameter for a PPPoE interface when it is required by
the ISP. The ISP uses this to identify the type of connection to use for the interface.
●
Each PPPoE interface is IP-enabled, i.e. it has an associated IP address. You may
specify this IP address in the WAN IP address if the address is allocated statically by
the ISP. If the IP address is obtained dynamically, specify this IP address as
“
0.0.0.0

Troubleshooting
This chapter suggests solutions to problems you may encounter in installing or using
the ADSL router, and provides instructions for using several IP utilities to diagnose
problems.
Contact Customer Support if these suggestions do not resolve the problem.

LEDs
Power LED
does not
illuminate
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 LED does
not illuminate
after phone
cable is
attached.
Verify that a standard telephone cable (called an RJ-11 cable) like
the one provided is securely connected to the DSL port and your
wall phone port.
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 a straight-through Ethernet cable to the
uplink port on a hub or a cross-over cable to a stand-alone PC. If
you connect the device to an ordinary hub port (not uplink), you
must use a straight-through cable. (To check: hold the connectors
at each end of the cable side-by-side with the plastic spring facing
down. Looking at the wires from left to right, if the first, second,
third, and sixth wires are in the same color on the two connectors,
then it is a straight-through cable. For a cross-over cable, wire 1
on one connector should be in the same color as wire 3 on the
other. The same is true with wires 2 and 6.)
Verify that your cable is sufficient for your network requirements.
A 100 Mbps network (10BaseTx) should use cables labeled CAT
5. A 10Mbps network may tolerate lower quality cables.

Troubleshooting Suggestion
My PC cannot
access Internet
Firstly, check to see if ADSL Link LED is solid on; if it is not, check
to see if the ADSL line is connected correctly.
If the method for acquiring the IP and DNS of the host is set to
Auto (Auto is recommended strongly), check to see if the IP
address has already been obtained correctly, and if you can ping
the IP address of the device
’
s LAN interface (192.168.1.1 by
default; refer to 8.2.1
ping to use the ping utility to check it out). If
you cannot ping the interface, check to see if the Ethernet cable is
OK.
If the current computer is specified with a private IP address,
make sure that it resides in the same segment as that of the
device
’
s LAN interface, the gateway is specified as the IP address
of the device
’
s LAN interface, and the DNS is specified as the IP
address of the device
’
s LAN interface or the DNS Server the ISP
allocates. Similarly, the host should be able to ping the IP address
of the device
’
s LAN interface.
If the host can communicate with the device normally but cannot
connect to the Internet, login to the web page of the device (refer
to Figure 4-39Status page) at first, and check to see if the WAN
interface of the device has acquired the Internet IP address.
My LAN PCs
cannot display
web pages on
the Internet.
Verify that the DNS server IP address specified on the PCs is
correct for your ISP, as discussed in the above item. If you specify
that the DNS server be assigned dynamically from a server, then
verify with your ISP that the address configured on the ADSL
router is correct, and then you can use the ping utility to test
connectivity with your ISP
’
s DNS server.
G
enerally, if a host can ping the Internet IP address, but cannot
open the web pages, the DNS server of the ISP may be
experiencing a failure for the time being. In this case, you can
manually change the host
’
s DNS to the IP address of a
normally
functioning DNS server, or login to the web page of the device
and manually modify the configuration for DNS Relay (refer to 4.3
DNS Relay), and then check by using the nslookup command as
instructed in 8.2.2
nslookup.
Web pages
I forgot/lost my
password.
If you have not changed the default password, try using
“
admin
”
as both the user ID and password. Otherwise, you can reset the
device to the default configuration by pressing the Reset Default
button on the rear panel of the device for at least 5 seconds. Then
connect to the web page again, type the default User ID and
password shown above.
Warning:
Resetting the device removes
any custom settings and returns all settings to their default values.
I cannot
access the
web pages
from my
browser.
Use the ping utility, discussed in the following section, to check
whether your PC can communicate with the device
’
s LAN IP
address (192.168.1.1 by default). If it cannot, check the Ethernet
cabling.
Verify that you are using Internet Explorer v5.0 or later, or
Netscape Navigator v4.61 or later.
Verify that the IP address defined for the PC is in the same subnet
as the IP address assigned to the LAN port on the ADSL router.

8.2 Diagnosing Problem Using IP Utilities
8.2.1 ping
Ping
is a command you can use to check whether your PC can recognize other
computers on your network and the Internet. A ping command sends messages to the
computer you specify. If the computer receives the messages, it sends messages in
reply. To use the command, you must know the IP address of the computer with which
you are trying to communicate.
On Windows-based computers, you can execute a ping command from the Start menu.
Click the
Start
button, and then click
Run
. In the
Open
text box, type a statement such
as the following:
Click
OK
. You can substitute any private IP address on your LAN or a public IP address
for an Internet site, if known.
If the target computer receives the messages, a
Command Prompt
window is
displayed:
Figure 8-1
Using the ping utility
If the target computer cannot be located, you will receive the message
Request timed
out
.
Using the ping command, you can test whether the path to the ADSL router is working
(using the preconfigured default LAN IP address 192.168.1.1) or another address you
assigned.
You can also test whether access to the Internet is working by typing an external
address, such as that for
www.yahoo.com
(216.115.108.243). If you do not know the IP
