Troubleshooting connection issues with Northwestern Wireless on macOS after a NetID Password change

After you reset your NetID password, you may find that your Mac has lost its access to the Northwestern wireless network. The most common problem relates to the password management system in macOS that stores most login credentials. These are ways to resolve this issue.


  1. Recreate Wireless Profile

    1. Delete the wireless profile. 
      1. Click Apple > System Preferences > Network.
      2. Select Wi-Fi in the left-hand pane, then click Advanced…
      3. In the Wi-Fi tab, select Northwestern from the list of Preferred Networks, then click the minus sign (-).
      4. Click OK to close the Advanced Wi-Fi Preference pane.
      5. Click Apply.
    2. Configure the wireless profile for macOS.

  2. Renew DHCP Lease

    1. Open Network from System Preferences.
    2. Select the wireless network from the left side.
    3. Click Advanced in the lower-right corner of the window.
    4. Select TCP/IP from the tabs at the top.
    5. Click Renew DHCP Lease.
When you try to connect to the Northwestern wireless network again, it will prompt you for your NetID and password, and should connect successfully. If you are still unable to connect, you can manually remove previous network login credentials from the Keychain:
  1. Open Keychain Access. (You can find this by searching within Finder or by opening Applications > Utilities.)
  2. Select Passwords from the categories listed in the lower-left corner of the window.
  3. Delete any passwords that contain WPA, WPA2, 802.1x, or Northwestern.
  4. Select Certificates from the categories listed in the lower-left corner of the window.
  5. Delete any certificates that contain netauth or netauth2.
