Accessing the Wireless Router’s Main Menu
If you are unable to access the wireless router’s main menu from a computer on your local 
network, check the following:
• Check the Ethernet connection between the computer and the router as described in the 
“Testing the LAN Path to Your Router” on page 6-5.
• Make sure your computer’s IP address is on the same subnet as the router. If you are using the 
recommended addressing scheme, your computer’s address should be in the range of 
192.168.1.2 to 192.168.1.254. See “Preparing a Computer for Network Access” in 
Appendix B for a link to a document that describes how to find your computer’s IP address. 
Follow the instructions in that document to configure your computer.
• If your router’s IP address has been changed and you do not know the current IP address, 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 Configuration and 
Password” on page 6-7.
• Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet 
Explorer, click Refresh to be sure the Java applet is loaded.
• Try quitting the browser and launching it again.
• Make sure 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 entering this 
information.
If the router does not save changes you have made, check the following:
• When entering configuration settings, be sure to click Apply before exiting a page, or your 
changes are lost. 
• Click Refresh or Reload in the Web browser. The changes may have occurred, but the Web 
browser may be caching the old configuration.
Note: If your computer’s IP address is shown as 169.254.x.x: Recent versions of 
Windows and MacOS will generate and assign an IP address if the computer 
cannot reach a DHCP server. These autogenerated addresses have the subnet 
address of 169.254.x.x. If your IP address is in this range, check the connection 
from the computer to the router and reboot your computer.

Troubleshooting the ISP Connection
If your router is unable to access the Internet, you should first determine whether the router is able 
to obtain a WAN IP address from the ISP. Unless you have been assigned a static IP address, your 
router must request an IP address from the ISP. You can determine whether the request was 
successful using the web Configuration Manager.
To check the WAN IP address: 
1.Launch your browser.
2.Access the main menu of the router’s configuration at http://192.168.1.1.
3.Under the Maintenance heading, select Router Status.
4.Check that an IP address is shown for the WAN port
If 0.0.0.0 is shown, your router has not obtained an IP address from your ISP.
If your router is unable to obtain an IP address from the ISP, you may need to force your cable or 
DSL modem to recognize your new router by performing the following procedure:
1.Turn off power to the cable or DSL modem. 
2.Turn off power to your router. 
3.Wait five minutes, and then reapply power to the cable or DSL modem. 
4.When the modem’s LEDs indicate that it has reacquired sync with the ISP, reapply power to 
your router.
If your router is still unable to obtain an IP address from the ISP, the problem may be one of the 
following:
• Your ISP may require a login program.
Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of login.
• If your ISP requires a login, you may have incorrectly set the login name and password.
• Your ISP may check for your computer’s host name.
Assign the computer host name of your ISP account as the Account Name in the Basic 
Settings page.
• Your ISP allows only one Ethernet MAC address to connect to Internet, and may check for 
your computer’s MAC address. In this case choose one of these options:
Inform your ISP that you have bought a new network device, and ask them to use the router’s 
MAC address.

OR
Configure your router to spoof your computer’s MAC address. This can be done in the Basic 
Settings page. 
If your router can obtain an IP address, but your computer is unable to load any Web pages from 
the Internet:
• Your computer may 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 will provide the addresses of one or two DNS 
servers for your use. If you entered a DNS address during the router’s configuration, reboot 
your computer, and verify the DNS address. For help, see the link to the online document, 
“Preparing a Computer for Network Access” in Appendix B. Or, you can configure your 
computer manually with DNS addresses, as explained in your operating system 
documentation.
• Your computer may not have the router configured as its TCP/IP gateway.
If your computer obtains its information from the router by DHCP, reboot the computer and 
verify the gateway address as described in “Preparing a Computer for Network Access” in 
Appendix B.
Troubleshooting a TCP/IP Network Using a Ping Utility
Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet 
to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP 
network is made very easy by using the ping utility in your computer or workstation.
Testing the LAN Path to Your Router
You can ping the router from your computer to verify that the LAN path to your router is set up 
correctly.
To ping the router from a computer running Windows 95 or later:
1.From the Windows toolbar, click Start and select Run.
2.In the field provided, type ping followed by the IP address of the router, as in this example:
ping 192.168.1.1
3.Click OK.

You should see a message like this one:
Pinging  with 32 bytes of data
If the path is working, you see this message:
Reply from < IP address >: 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 the LAN port LED is on. If the LED is off, follow the instructions in 
“Local or Internet Port LEDs Not On” on page 6-2.
– Check that the corresponding Link LEDs are on for your network interface card and 
for the hub ports (if any) that are connected to your workstation and router.
• Wrong network configuration
– Verify that the Ethernet card driver software and TCP/IP software are both installed 
and configured on your computer or workstation.
– Verify that the IP address for your router and your workstation are correct and that the 
addresses are on the same subnet.
Testing the Path from Your Computer to a Remote Device
After verifying that the LAN path works correctly, test the path from your computer to a remote 
device. From the Windows run menu, type:
PING -n 10 
where  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:
– Check that your computer has the IP address of your router listed as the default gateway. If 
the IP configuration of your computer is assigned by DHCP, this information will not be 
visible in your computer’s Network Control Panel. Verify that the IP address of the router 
is listed as the default gateway. For help see the link to the online document in “Preparing 
a Computer for Network Access” in Appendix B.
– Check to see that the network address of your computer (the portion of the IP address 
specified by the netmask) is different from the network address of the remote device.
– Check that your cable or DSL modem is connected and functioning.

– If your ISP assigned a host name to your computer, enter that host name as the Account 
Name in the Basic Settings page.
– Your ISP could be rejecting the Ethernet MAC addresses of all but one of your computers. 
Many broadband ISPs restrict access by allowing traffic only from the MAC address of 
your broadband modem, but some ISPs additionally restrict access to the MAC address of 
a single computer connected to that modem. If this is the case, you must configure your 
router to “clone” or “spoof” the MAC address from the authorized computer. 
Restoring the Default Configuration and Password
This section explains how to restore the factory default configuration settings, changing the 
router’s administration password to password and the IP address to 192.168.1.1. You can erase the 
current configuration and restore factory defaults in two ways:
• Use the Erase function of the router (see “Erasing the Configuration” on page 4-6).
• Use the Default Reset button on the rear panel of the router. Use this method for cases when 
the administration password or IP address is not known.
To restore the factory default configuration settings if you do not know the administration 
password or IP address, you must use the Default Reset button on the rear panel of the router.
1.Press and hold the Default Reset button until the Test LED turns on (about 5 seconds).
2.Release the Default Reset button, and then wait for the router to reboot.
Problems with Date and Time
To view the current date and time of day, select E-Mail below the Content Filtering heading on the 
main menu. The wireless router uses the Network Time Protocol (NTP) to obtain the current time 
from one of several network time servers on the Internet. Each entry in the log is stamped with the 
date and time of day. Problems with the date and time function can include:
• Date shown is January 1, 2003. Cause: The router has not yet successfully reached a network 
time server. Check that your Internet access settings are configured correctly. If you have just 
completed configuring the router, wait at least five minutes, and then check the date and time.
• Time is off by one hour. Cause: The router does not automatically sense daylight savings time. 
On the E-Mail page, select or clear the check box marked “Adjust for Daylight Savings Time”.
