Troubleshooting Ping Procedure

If at any time during the ping procedure you do not receive a return message for a successful ping, this means that the address you are pinging has been changed and is causing a conflict or is no longer available. Check the address in the configuration pages and make any necessary corrections using the console mode. After you have made the corrections, continue with the ping procedure.

Note: Linux users can perform steps 3 through 7 after opening a terminal.

  1. Do one of the following:

    Windows Vista Users

      1. Click Windows Start.

      2. In the Search box, type Command Prompt and press ENTER.

      3. In the resulting list, right-click Command Prompt and select Run as Administrator.

      4. Type ipconfig /all and press ENTER.

    Windows XP, 2000 and NT Users

      1. Click Windows Start > Run.
      2. In the Run dialog box, type cmd and click OK.
      3. Type ipconfig /all and press ENTER.

    Windows Me, 98, and 95

      1. Click Windows Start > Run.
      2. In the Run dialog box, type command and click OK.

      3. Type winipconfig /all and press ENTER.

         

    This displays IP configuration, including values like the following:

    IP Address: 192.168.2.2
    Subnet Mask: 255.255.255.0
    Default Gateway: 192.168.2.1 (This is the Default Gateway of your LAN)
    DNS Server: 192.168.2.1



    If you do not see information for the Ethernet adapter connection information, your computer is not communicating with your Ethernet adapter.

    If you receive a message that your media is disconnected, your computer is communicating with your adapter but has not received an IP address from your router. If you are using a wireless connection to the router, verify that the wireless security settings for your adapter match the wireless security settings on your router.

    If you have an IP address of 169.254 or 0.0.0.0, verify that your wireless security settings for your adapter match the wireless security settings on your router and repair the network connection on your computer.

  1. Type Ping 127.0.0.1 and press ENTER. This is your local host address and this will ensure that the TCP/IP protocol is installed and functioning properly. If you cannot complete this ping, you must install the TCP/IP framework for your operating system. See your operating system documentation for information on how to install the TCP/IP framework.

  2. Type Ping followed by the IP address you recorded in step 2, and press ENTER. This will ensure that your computer is responding to requests. If you cannot complete this ping, make sure all the cables are properly connected and that all the correct drivers are installed.

  3. Type Ping followed by the LAN IP address, which is the Default Gateway you recorded in step 2, and press ENTER. This checks the communication with your gateway or wireless router. This will ensure that you can get to the router. If you can establish communication with the router, you can access the configuration pages and configure the settings. If you cannot complete this ping, make sure the power cord of the router is plugged in and that it is properly connected to your computer.

  4. Type Ping followed by the outside WAN IP address of your router. This is not the same as the Default Gateway for your LAN that you saw in step 2. This address can be obtained from the Status page of the router. This procedure will ensure that you have access to the internet.

  5. Type Ping followed by the DNS Server address you recorded in step 2, and press ENTER. This will allow you to resolve valid Internet host names to IP addresses and to verify that you can access the Internet.
