Configuring Automatic Addressing for the CUMC Network

All computers connecting to the CUMC network must be registered and inventoried before they can connect. Please see the Connecting to the Wired CUMC Network page for detailed instructions.

Once registration is processed the computer should automatically connect. If not please make sure it is set to use automatic addressing, also called DCHP. The instructions on this page will help you set DHCP on Windows or Macintosh.

Set automatic addressing (DHCP) on a Windows computer
  1. Open the Control Panel:
    • Windows 7 - click the Start button in the lower left and select the Control Panel link.
    • Windows 8.1 and 10 - use the computer's Search bar (in 8.1 swipe or click the upper right corner screen, in 10 use the search box in the lower left taskbar) to find the Control Panel. You can also look for it in the apps list under a Windows System heading.
  2. Select Network and Internet if listed, then Network and Sharing Center.

  3. Select the Change adapter settings link to the left.
  4. Find the connection you want to check or change, usually Local Area Connection (not VPN) or Ethernet, and right-click on it.

  5. Select Properties from the menu that appears. If prompted, enter the computer's Administrative login and password. If you do not know this please contact the IT staff that manages your computer to have them set DHCP for you.
  6. Near the center of the network connection's Properties window scroll down to find Internet Protocol Version 4 (TCP/IP). Click on it once to highlight, then select the Properties button.

  7. Make sure the General tab is selected. If you see an IP address or other specific information rather than the automatic options, read this entire step before changing anything.
    To set automatic addressing select the options for:
    • Obtain an IP address automatically
    • Obtain DNS server address automatically
    Changing to automatic IP and DNS addressing will immediately remove any IP address and server information that may be stored here, if you will need these settings on another network you should make note of them before removing.

  8. Click the OK button in the lower right, then OK again to exit and save the changes. Close any Network or Control Panel windows that are still open.
  9. Restart your computer; it will automatically connect to the campus network.

Set automatic addressing (DHCP) on a Macintosh computer

  1. Open System Preferences (from your dock, or click the Apple icon at the upper left corner of your screen, then System Preferences in the menu that appears).
  2. Select the Network icon.
  3. Click on the network connection you need to configure (usually Ethernet) from the list on the left to highlight it, then select the Advanced button in the lower right.

  4. Make sure TCP/IP is selected in the top menu bar and look at the Configure IPv4 option.
    • If it is set to Using DHCP with manual address, the Mac is using a static address. If there are other networks you use regularly that require this you will want to write down the IPv4 Address and other information in this screen, and check with IT support for the network(s) to see if it is required.
    • Select Using DHCP from the Configure IPv4 drop down menu to set automatic addressing.
