It’s convenient that our laptops quickly remember familiar networks without having to ask for permission to connect, but sometimes, you’ll want to forget a network manually. For example, if you’re having a hard time with your office or home Wi-Fi, sometimes all you need to do is remove the network from your Wi-Fi settings and then reconnect. This guide will show you how to forget a network on a Mac in three easy steps. We’ll be using the newest version of MacOS, Catalina in our guide, however, the steps are the same for most versions of MacOS.
Step 1: Open Network Preferences
First off, go ahead and mouse up to your Finder bar, then click your Wi-Fi icon. This will open a list of all your nearby Wi-Fi networks. From here, click on Open Network Preferences at the bottom of the list.
This is where you’ll find all the advanced settings for your Mac’s networked devices.
Step 2: Open Advanced Settings
Here you can add and remove network adapters, turn Wi-Fi off or on, and configure the settings for your individual Wi-Fi networks — whether you want to automatically connect to particular networks, or ask to join new networks. This is also where you can see your network IP address, which can be helpful for diagnosing other network issues. Keep this menu in mind in case forgetting a network doesn’t fix your Wi-Fi woes as it contains useful information for further troubleshooting. That being said, all we will be doing here though is clicking on Advanced button down at the bottom, and moving on to our final step.
Step 3: Remove Network
After you have clicked the Advanced button, you’re going to see a lot of options and preference panes you don’t need to worry about. This advanced menu lets you add networks manually. You can also use it to check network hardware settings, access TCP/IP settings, or find your Mac’s unique Wi-Fi address. If there are different Wi-Fi networks you use regularly, you can select and drag the network to customize their order. You can change the order of the networks by clicking and dragging the network names.
Removing a network from your list is very easy. All you have to do is select it and look for the minus icon at the bottom of the network list. Your Mac will forget this network if you click on the minus button.
If you’re still experiencing issues, try rebooting your device and connecting to the internet again. And if you’re still having trouble after that, it might be time to check out one of our other guides — you might have a bigger problem on your hands.
