Tip 2: Power Off and Power On Your Router

In case you are still facing trouble with your internet after enabling the Wi-Fi, try turning off your router and turning it back on. You can do this by using the “On/Off” switch at the back of the router. Also, make sure that all the cables are connected correctly. After you turn on the router again, wait at least 2 minutes before trying to connect again.

Tip 3: Disconnect All External Devices

Make sure the devices you connect to your MacBook have shielding. If they don’t, they might make your Wi-Fi or internet stop working. First, disconnect every device from your Mac, like the mouse, keyboard, and hard drive. Then, try connecting to the internet again. If you can go online now, it means one of your devices is causing the problem.

To resolve this, connect your devices back one by one to notice which one is causing trouble. If you find the one causing the problem, get it repaired or buy a new one.

Tip 4: Restart Your Mac

On your Mac, in the top left corner, hit the “Apple” icon. As the drop-down list appears, tap the “Restart” option. Then, in the pop-up window, press the “Restart” button again to switch Mac off. Afterward, wait a few seconds, and it will turn on again.

Tip 8: Move Closer to Router

Usually, when your Mac is far from the Wi-Fi router or network, it may have trouble connecting. Even if it shows connected, the signal might need to be stronger to give you a good internet connection. The bars in the Wi-Fi symbol on your Mac’s menu bar show how strong the signal is. Move and place your Mac where the signal bars reach at least three. This will build a stronger Wi-Fi connection.
