Why does my MacBook refuse to connect to WiFi?
Your MacBook may refuse to connect to WiFi due to various reasons such as incorrect network settings, outdated software, or incorrect WiFi password. It’s also possible that the WiFi network itself is experiencing issues, causing your MacBook to fail to connect. To troubleshoot the issue, try restarting your router, modem, and MacBook, and then attempt to reconnect to the WiFi network.
Additionally, ensure that your WiFi is enabled on your MacBook and that you’re in range of the network. You can also try forgetting the WiFi network on your MacBook and then re-adding it to see if that resolves the issue. If none of these steps work, it may be worth resetting your network settings or seeking further assistance from an IT professional or Apple support.
How do I reset my MacBook’s network settings?
To reset your MacBook’s network settings, click on the Apple menu and select “System Preferences.” Then, click on “Network” and select “Advanced” at the top right corner of the window.
