Troubleshooting Login Problems
If you are unable to log in to the wireless router, check the following:
•
If you are using an Ethernet-connected computer, check the Ethernet connection between the
computer and the router as described in the previous section.
•
Make sure that you are using the correct login information. The factory default login name is
admin
, and the password is
password
. Make sure that Caps Lock is off when you enter this
information.
•
Typically, your computer’s address should be in the range of 192.168.1.2 to 192.168.1.254.
Refer to your computer’s documentation for help with finding your computer’s IP address.
Internet light stays
amber.
When the router is turned on, the Internet light turns amber for about 20 seconds
and then turns green. If the light does not turn green, the router has a problem.
If the Internet light is still amber 1 minute after turning on power to the router:
1.
The Internet is not accessible. Confirm that you have the correct internet
setting.
2.
Clear the router’s configuration to factory defaults. This will set the router’s
IP address to 192.168.1.1. This procedure is explained in
“Restoring the
Default Password and Configuration Settings” on page 42
.
3.
Turn the power off and back on to see if the router recovers.
Internet or LAN port lights
are off.
If either the LAN or Internet lights do not light when the Ethernet connection is
made, check the following:
1.
Make sure that the Ethernet cable connections are secure at the router and
at the computer.
2.
Make sure that power is turned on to the connected computer.
3.
Be sure you are using Ethernet cables like the cable that was supplied with
the wireless router.
See
“Connecting Your Wireless Router” on page 13
for instructions.
If your computer’s IP address is 169.254.x.x, verify that you have a good
connection from the computer to the router, and then restart your computer.

Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using
Internet Explorer, click
Refresh
to be sure that the Java applet is loaded. Try closing the
browser and starting it again.
Checking The Internet Service Connection
If your router is unable to access the Internet, check that the Internet connection is working, and
then check that the wireless router can get an Internet address.
Check that the Internet connection is working:
1.
Internet connection
. First verify that your cable or ADSL modem has a successful
connection. The cable or ADSL modem status lights indicate if the modem connection is
successful or not. Check your modem documentation, or call your Internet Service Provider
for help with verifying that the modem has a successful connection.
2.
Wireless router Internet light is green or blinking green
. If your Internet light is green or
blinking green, then you have a good Internet connection, and your wiring is correct.
3.
Wireless router Internet light blinking amber
. If your Internet light is blinking amber, then
your wireless router is attempting to make an Internet connection with the service provider.
The light should turn green within several minutes. If it does not, check the Internet
connection on the modem.
4.
Wireless router Internet light
off
. If the Internet light is off, verify that the Ethernet cable is
securely connected between the cable or ADSL modem, and that both the modem and wireless
router are turned on.
Obtaining an Internet IP Address
If your wireless router is unable to access the Internet, and your Internet light is amber or blinking
amber, check the wireless router to see if it is able to get an Internet IP address from your service
provider. Unless you have a static IP address, your wireless router automatically requests an IP
address from your service provider.
To check the Internet IP address from the browser interface:
1.
Log in to the wireless router.
2.
Select
Router Status
under Maintenance on the main menu to check that an IP address is
shown for the Internet port. If 0.0.0.0 is shown, your wireless router has not obtained an IP
address from your service provider.

Troubleshooting

If your router is unable to obtain an IP address from the your service provider, the problem might
be one of the following:
•
Your service provider might require a login. Ask your service provider whether they require
PPP over Ethernet (PPPoE) login.
•
The service name, user name, and password might be set incorrectly. See
“Troubleshooting
PPPoE”
.
•
Your service provider might check for your computer’s host name.
Assign the computer host name of your ISP account to the wireless router in the Basic Settings
screen.
•
Your service provider allows only one Ethernet MAC address to connect to Internet, and
might check for your computer’s MAC address. In this case, do one of the following:
–
Inform your service provider that you have bought a new network device, and ask them to
use the wireless router’s MAC address.
–
Configure your router to spoof your computer’s MAC address. This can be done in the
Basic Settings screen. Refer to the online help, which you can access from the wireless
router main menu.
Troubleshooting PPPoE
To troubleshoot a PPPoE connection:
1.
Log in to the wireless router.
2.
Select
Router Status
under Maintenance on the main menu.
3.
Click the
Connection Status
button.
4.
If all the steps indicate OK, then your PPPoE connection is up and working.
5.
If any of the steps indicate Failed, you can attempt to reconnect by clicking
Connect
. The
wireless router will continue to attempt to connect indefinitely.
If you cannot connect after several minutes, you might be using an incorrect service name,
user name, or password. There also might be a provisioning problem with your ISP.
Unless you connect manually, the wireless router will not authenticate using
PPPoE until data is transmitted to the network.

Troubleshooting Internet Browsing
If your wireless router can obtain an IP address but your computer is unable to load any Web pages
from the Internet, check the following.
•
Your computer might not recognize any DNS server addresses.
A DNS server is a host on the Internet that translates Internet names (such as www addresses)
to numeric IP addresses. Typically your ISP provides the addresses of one or two DNS servers
for your use. If you entered a DNS address when you configured the wireless router, restart
your computer. Alternatively, you can configure your computer manually with DNS addresses,
as explained in the documentation for your computer
.
•
Your computer might not have the wireless router configured as its default gateway.
Restart the computer, and verify that the wireless router address (192.168.1.1) is listed by your
computer as the default gateway address.
Troubleshooting Connectivity Using the Ping Utility
Most computers and routers have a diagnostic utility called
ping
that sends an request to a target
device. The device then replies. The ping utility makes it easy to troubleshoot a network..
Testing the Path from a PC to Your Router
You can ping the wireless router to verify that the LAN path from your computer to your router is
set up correctly.
To ping the wireless router:
The factory default wireless router IP address is 192.168.1.1. However, if the
router detects a conflict with the address it gets from your modem, it
automatically picks a different address for itself. In this case, you can log in to
the router using
www.routerlogin.net
to verify its LAN IP address. Select
LAN
IP Setup
under Advanced on the main menu. Take note of the LAN TCP/IP
setup IP address, which should match the default gateway IP address on your
computer.
This section includes advanced troubleshooting techniques.

If the path is working, you see this message:
Reply from 192.168.1.1: bytes=32 time=NN ms TTL=xxx
If the path is not working, you see this message:
Request timed out
If the path is not functioning correctly, you could have one of the following problems:
•
Wrong physical connections
–
Make sure that the LAN port light is on. If the light is off, follow the instructions in
“Front Panel” on page 3
.
–
Check that the corresponding lights are on for your computer’s network interface
card.
•
Wrong network configuration
–
Verify that the Ethernet card driver software and TCP/IP software are both installed
and configured on your computer.
–
Verify that the IP address for your router and your computer are correct and that the
addresses on both begin with 255.255.255.0.
Testing the Path from a PC to the Internet
After verifying that the path between your computer and the wireless router works correctly, test
the path from your PC to the Internet. From the Windows Start > Run... menu, type:
PING -n 10
<IP address>
where <
IP address
> is the IP address of a remote device such as your ISP’s DNS server.
If the path is functioning correctly, replies as in the previous section are displayed. If you do not
receive replies:
