What are the reasons to reset Wi-Fi on my Mac?
Resetting Wi-Fi on your Mac can resolve various connectivity issues, such as dropped connections, slow internet speeds, or an inability to connect to a network. If you’re experiencing any of these problems, resetting Wi-Fi can help restore your internet connection. Additionally, if you’ve recently changed your Wi-Fi network or router, resetting Wi-Fi on your Mac can ensure a smooth transition and prevent any potential conflicts.
Another reason to reset Wi-Fi on your Mac is to remove any saved network information, which can be useful if you’re selling or giving away your device. By resetting Wi-Fi, you’ll remove all saved network passwords and settings, ensuring that the new owner can start fresh and set up their own network connections.
How do I reset Wi-Fi on my Mac using the Network Preferences?
To reset Wi-Fi on your Mac using the Network Preferences, follow these steps: Click the Apple menu and select “System Preferences.” Then, click on “Network” and select “Advanced” from the menu. Next, click on the “TCP/IP” tab and click the “Renew DHCP Lease” button. Finally, click “OK” to save the changes. This will reset your Wi-Fi connection and obtain a new IP address from your router.
Alternatively, you can also reset Wi-Fi by clicking on the “Wi-Fi” tab in the Network Preferences and selecting “Forget Network” from the menu.

Make sure to have your network password handy, as you’ll need to re-enter it to connect to the network.
What is the difference between resetting Wi-Fi and restarting my Mac?
Resetting Wi-Fi on your Mac is a more targeted approach than restarting your device. When you reset Wi-Fi, you’re specifically resetting the Wi-Fi connection and removing any saved network information. This can help resolve connectivity issues without affecting other system settings or applications. On the other hand, restarting your Mac will shut down and restart the entire system, which can sometimes resolve connectivity issues but may also affect other system settings or applications.
In general, it’s recommended to try resetting Wi-Fi first, as it’s a less invasive approach that can often resolve connectivity issues without disrupting other system functions. If resetting Wi-Fi doesn’t resolve the issue, you can try restarting your Mac as a next step.
Will resetting Wi-Fi on my Mac affect my other network settings?
Resetting Wi-Fi on your Mac will only affect your Wi-Fi settings and will not impact other network settings, such as Ethernet or VPN connections. When you reset Wi-Fi, you’ll remove any saved Wi-Fi network information, including passwords and settings. However, your other network settings will remain intact, and you won’t need to reconfigure them.
It’s worth noting that if you’re using a VPN connection, you may need to re-establish the connection after resetting Wi-Fi. This is because some VPN connections may rely on the Wi-Fi connection to function properly. However, your VPN settings themselves will not be affected by resetting Wi-Fi.
How do I reset Wi-Fi on my Mac using the Terminal app?
To reset Wi-Fi on your Mac using the Terminal app, follow these steps: Open the Terminal app and type the command “sudo killall mDNSResponder” followed by the enter key. This will restart the mDNSResponder process, which is responsible for managing Wi-Fi connections on your Mac. Next, type the command “sudo killall -HUP mDNSResponder” followed by the enter key. This will reset the Wi-Fi connection and remove any saved network information.
Alternatively, you can also use the command “networksetup -resetnetworksettings” to reset Wi-Fi on your Mac. This command will remove all saved network information, including Wi-Fi and Ethernet settings. Make sure to have your network passwords handy, as you’ll need to re-enter them to connect to the network.
Will resetting Wi-Fi on my Mac delete my saved network passwords?
Yes, resetting Wi-Fi on your Mac will remove any saved network passwords. When you reset Wi-Fi, you’ll remove all saved network information, including passwords and settings. This means that you’ll need to re-enter your network password to connect to the network after resetting Wi-Fi.
However, if you’re using a password manager or Keychain to store your network passwords, they will not be affected by resetting Wi-Fi. You can still access your saved passwords through the password manager or Keychain, and you can use them to reconnect to the network.
How often should I reset Wi-Fi on my Mac?
It’s not necessary to reset Wi-Fi on your Mac regularly, as it’s usually only required when you’re experiencing connectivity issues or when you’ve changed your Wi-Fi network or router. However, if you’re experiencing frequent connectivity issues or if you’re selling or giving away your Mac, it’s a good idea to reset Wi-Fi to ensure a smooth transition and to remove any saved network information.
In general, it’s recommended to reset Wi-Fi on your Mac only when necessary, as it can sometimes cause minor disruptions to your internet connection. If you’re unsure whether to reset Wi-Fi or not, you can try restarting your Mac or router first to see if that resolves the issue.
