Troubleshooting7-1 202-10090-01, April 2005 Chapter 7 Troubleshooting This chapter gives information about troubleshooting your WGT624 v3 108 Mbps Wireless Firewall Router. After each problem description, instructions are provided to help you diagnose and solve the problem. Basic Functioning After you turn on power to the router, the following sequence of events should occur: 1.When power is first applied, verify that the Power LED is on. 2.After approximately 10 seconds, verify that: a.The Local port LEDs are lit for any local ports that are connected. If a port’s LED is lit, a link has been established to the connected device. If a LAN port is connected to a 100 Mbps device, verify that the port’s LED is green. If the port is 10 Mbps, the LED will be amber. b.The Wireless port LED is lit. (Note: The LED is off in factory default setting and is enabled/LIT after you run the Configuration Assistant.) c.The Internet port LED is lit. If any of these conditions does not occur, refer to the appropriate following section. Power LED Not On If the Power and other LEDs are off when your router is turned on: • Make sure that the power cord is properly connected to your router and that the power supply adapter is properly connected to a functioning power outlet. Note: Product updates are available on the NETGEAR Web site at www.netgear.com/support/main.asp. Documentation updates are available on the NETGEAR, Inc. Web site at www.netgear.com/docs.
Reference Manual for the 108 Mbps Wireless Firewall Router WGT624 v3 7-2Troubleshooting 202-10090-01, April 2005 • Check that you are using the 12 V DC 1A power adapter supplied by NETGEAR for this product. If the error persists, you have a hardware problem and should contact technical support. LEDs Never Turn Off When the router is turned on, the LEDs turns on for about 10 seconds and then turn off. If all the LEDs stay on, there is a fault within the router. If all LEDs are still on one minute after power up: • Cycle the power to see if the router recovers. • 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 7-7. If the error persists, you might have a hardware problem and should contact technical support. Local or Internet Port LEDs Not On If either the LAN LEDs or WAN LED do not light when the Ethernet connection is made, check the following: • Make sure that the Ethernet cable connections are secure at the router and at the hub or workstation. • Make sure that power is turned on to the connected hub or workstation. • Be sure you are using the correct cable: When connecting the router’s WAN port to a cable or DSL modem, use the cable that was supplied with the cable or DSL modem. This cable could be a standard straight-through Ethernet cable or an Ethernet crossover cable.
Reference Manual for the 108 Mbps Wireless Firewall Router WGT624 v3 Troubleshooting7-3 202-10090-01, April 2005 Troubleshooting the Web Configuration Interface If you are unable to access the router’s web Configuration interface from a PC on your local network, check the following: • Check the Ethernet connection between the PC and the router as described in the previous section. • Make sure your PC’s IP address is on the same subnet as the router. If you are using the recommended addressing scheme, your PC’s address should be in the range of 192.168.1.2 to 192.168.1.254. Refer to “Verifying TCP/IP Properties” on page C-6 or “Verifying TCP/IP Properties for Macintosh Computers” on page C-17 to find your PC’s IP address. Follow the instructions in Appendix C to configure your PC. Note: If your PC’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 auto-generated addresses are in the range of 169.254.x.x. If your IP address is in this range, check the connection from the PC to the router and reboot your PC. • If your router’s IP address has been changed and you don’t 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 7-7. • 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 in the web Configuration Interface, check the following: • When entering configuration settings, be sure to click the APPLY button before moving to another menu or tab, or your changes are lost. • Click the Refresh or Reload button in the web browser. The changes may have occurred, but the web browser may be caching the old configuration.
Reference Manual for the 108 Mbps Wireless Firewall Router WGT624 v3 7-4Troubleshooting 202-10090-01, April 2005 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 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 PCs host name. Assign the PC Host Name of your ISP account as the Account Name in the Basic Settings menu. • Your ISP only allows one Ethernet MAC address to connect to Internet, and may check for your PC’s MAC address. In this case: Inform your ISP that you have bought a new network device, and ask them to use the router’s MAC address.
Reference Manual for the 108 Mbps Wireless Firewall Router WGT624 v3 Troubleshooting7-5 202-10090-01, April 2005 OR Configure your router to spoof your PC’s MAC address. This can be done in the Basic Settings menu. If your router can obtain an IP address, but your PC is unable to load any web pages from the Internet: • Your PC 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 PC and verify the DNS address as described in “Verifying TCP/IP Properties” on page C-6. Alternatively, you may configure your PC manually with DNS addresses, as explained in your operating system documentation. • Your PC may not have the router configured as its TCP/IP gateway. If your PC obtains its information from the router by DHCP, reboot the PC and verify the gateway address as described in “Verifying TCP/IP Properties” on page C-6. 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 PC or workstation. Testing the LAN Path to Your Router You can ping the router from your PC to verify that the LAN path to your router is set up correctly. To ping the router from a PC running Windows 95 or later: 1.From the Windows toolbar, click on the Start button 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 on OK. You should see a message like this one: Pinging with 32 bytes of data
Reference Manual for the 108 Mbps Wireless Firewall Router WGT624 v3 7-6Troubleshooting 202-10090-01, April 2005 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 7-2. — 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 PC 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 PC to a Remote Device After verifying that the LAN path works correctly, test the path from your PC 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 PC has the IP address of your router listed as the default gateway. If the IP configuration of your PC is assigned by DHCP, this information will not be visible in your PC’s Network Control Panel. Verify that the IP address of the router is listed as the default gateway as described in “Verifying TCP/IP Properties” on page C-6. — Check to see that the network address of your PC (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.
Reference Manual for the 108 Mbps Wireless Firewall Router WGT624 v3 Troubleshooting7-7 202-10090-01, April 2005 — If your ISP assigned a host name to your PC, enter that host name as the Account Name in the Basic Settings menu. — Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many broadband ISPs restrict access by only allowing traffic from the MAC address of your broadband modem, but some ISPs additionally restrict access to the MAC address of a single PC connected to that modem. If this is the case, you must configure your router to “clone” or “spoof” the MAC address from the authorized PC. 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 5-8). • 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 without knowing 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 wait for the router to reboot. Problems with Date and Time The E-Mail menu in the Content Filtering section displays the current date and time of day. The WGT624 v3 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 check the date and time again. • Time is off by one hour. Cause: The router does not automatically sense Daylight Savings Time. In the E-Mail menu, check or uncheck the box marked “Adjust for Daylight Savings Time”.
