Sunday Monday (delayed) day of our column MM Answers! 😉

The question of the day:

How to use your Mac as a wireless router?

Network sharing

Did you know that you can turn your Mac into a wireless router anywhere? If your answer is “no”, know that this tool is very interesting if you are in a location that the Wi-Fi signal is bad or if you are in a location without the availability of a wireless network.

Following the step-by-step below you can connect your iGadgets, computers or any other device you want on a wireless network created by your computer!

Setting up sharing

Connect an Ethernet cable or activate a Bluetooth internet connection with your computer and follow these steps:

  1. From the apple menu, in the upper left corner of the macOS interface, select "System Preferences".

System Preferences

  1. In the window that appears, select the “Sharing” area.
  2. Click on the lock in the lower left corner of the window and authenticate your Mac's administrator account.
  3. Select "Share Internet" in the sidebar. It is important to note that you should not check the checkbox yet, just select the item.
  4. In the item “Share your connection from:”, select your computer's primary internet connection option in this example, we will use Ethernet / Thunderbolt.

Security - Internet sharing

  1. In the item “For computers using:”, select the Wi-Fi box. This option guides your Mac to create a wireless network and allows any device that connects to it to have access to the internet signal originating from the Ethernet / Thunderbolt cable .
  2. Click on “Wi-Fi options” and define a name for your network as well as an operating channel.

Security - Internet sharing

  1. In "Security" choose the option Personal WPA2, set and verify a password for your network.

Start - Internet Sharing

  1. Click "OK" and return to the "Sharing" menu in System Preferences.
  2. Check the "Share Internet" text box.
  3. Click "Start".

Ready! With this option enabled, your Mac becomes a wireless router and allows other devices to access the internet using your computer's wired connection.
