Wireless Network / Remove or forget a wireless network on a macOS computer

Objective

• To provide instruction on removing a wireless network from the list of networks on a macOS computer

Environment

• 10139: Wireless Network
• Personally Owned Computer
  • macOS
    • OS X

Cause

• If you experience an issue when connecting to a wireless network on a computer running OS X, try forgetting the wireless network. This enables the computer to reset settings — usernames, passwords, or configurations — allowing the device to reconnect to the network 

Resolution 

1. To forget or delete a wireless network in OS X, select the Wi-Fi symbol in the menu bar
2. Click Open Network Preferences from the drop-down menu
3. In the Network window, select Wi-Fi in the left panel
4. Click the Advanced... button
5. Choose the wireless network you want to delete and click the minus button
6. Click OK
7. If prompted, click the Apply button to confirm changes
8. You may need to uninstall the MU-WIRELESS profile if you have it installed. This can be accomplished by going to System Preferences > Profiles. Remove anything that references MU-WIRELESS by selecting it and clicking the minus button
