Ethernet Help

Make sure that your cables are firmly plugged in.

  1. Obtain your IP address.
  • In Windows, click the "Start" button in the lower left hand corner. Type "cmd" in the Search text box and press enter. A black window will open. Type "ipconfig /all" at the command prompt and press enter again. Look for an entry displayed marked "Ethernet adapter Local Area Connection" (or similar), and under that for the number marked "IP4 address".
  • In MacOS 13.x, select the Apple Menu, and open System Properties. Click on Network, and in the window that opens, select "Built-In-Ethernet" from the 'Show:' drop-down box. Select the TCP/IP tab. Look for a line that is labeled "IP Address:".

What each IP address means:


    1. If it starts with "69.56": Congratulations-you're registered! If you cannot get on the internet, make sure your cable is plugged in correctly and try clearing your web browser's cache or temporary internet files or reboot.
    2. If it starts with "172.31": This is a pre-registration address. Try registering again and make sure to wait the recommended 15 minutes before attempting to browse.
    3. c. If it starts with "172.30": Your computer has been put on the jail network due to an Acceptable Use Policy violation. Contact the service desk for more information.
    4. d. If it starts with "169": this is an automatically configured address set by Windows when it cannot communicate to our server.
    5. a. If it starts with "169": this is an automatically configured address set by Windows when it cannot communicate to our server.
      1. In Windows: Press "Start" and click "Control Panel".
        1. Click on "Network and Internet"
        2. Click on "Network and Sharing Center"
        3. Click on the blue "Local Area Connection"
        4. Click "Properties"
        5. In the box that appears, select "Internet Protocol Version 4 (TCP/IP4) from the list and click "Properties" Select both "Obtain an IP address automatically" and "Obtain DNS server addrss automatically". Click "OK".
      2. In MacOS 10.x, select the Apple Menu, and open System Properties. Click on Network, and in the window that opens, select "Ethernet". Under the 'Configure IPv4' drop-down box, select "Using DHCP".
    6. If you see 'media disconnected', check your ethernet cord. It may not be properly connected or damaged. Make sure the ethernet driver is installed and enabled.
  2. If none of the above works, call us at (509)-963-2001.
