It is possible that on some occasion you need share your Mac's network connection with other devices. This can happen in places where you have your sea connected directly to the Ethernet port because there is no Wi-Fi connectivity.
Usually if there is an option to connect our equipment directly to Wi-Fi we can also connect the rest of the devices, but when this is not possible we can directly connect our Mac to the Ethernet port through a hub and share the connection from the equipment with other devices, be it whichever. In this way we will be creating a Wi-Fi network to which we ourselves will put a password for the rest to connect.
How to share your Mac's network connection with other devices
It may seem complicated to carry out but sharing our network with other computers or devices is not complicated. Keep in mind that one of the computers (in this case our Mac) has to be connected to the network via Ethernet cable, without this it will not be possible to perform this action.
Once we have our Mac connected to the network, we simply have to access the Apple menu at the top and click on System Preferences to start sharing the network. Once there, click on the share folder (in the case of macOS Monterey, which is the most current) and click on the option "Share internet" in the list of services.
- Click the "Share connection from" drop-down menu, and then select the internet connection you want to share. For example, if you connect to the internet via Ethernet, select Ethernet.
- In the "With other computers via" list, select the port that the other computers will use to access the shared internet connection. For example, if you want to share your internet connection via Wi-Fi, select Wi-Fi.
- If you choose Wi-Fi from the "With other computers via" list, click "Wi-Fi Options," configure the network to share the Internet, and then click OK.
- Network name: Enter a name for the shared connection.
- Channel: Click the Channel drop-down menu, then choose another channel if you don't want to use the default channel.
- Safety: If available, click the Security drop-down menu and choose an option.
- If all computers using connection sharing support WPA3, choose “WPA3 Personal”.
- If any of the computers that use connection sharing only support WPA2, please choose “WPA2 / WPA3”.
- Password: Please enter a password. If you want to see the current password, select the option "Show password" that appears below the password.
- In the list of services on the left, select the "Internet Sharing" option.
- If you are sure you want to share the internet, click Start. Otherwise, click Cancel.
In this way you can share the network from your Mac connected directly from the Ethernet port. It is quite easy to carry out this process, but an adapter is obviously required to carry out the action. In any case most of the hubs we have today available for Mac add the option of connecting via cable.
It is the best option to create a non-existent Wi-Fi network
We can say that this option is very valid for those who do not have the option to connect to Wi-Fi directly. This happens much more than we think and is that sometimes we have an Ethernet network cable that reaches all rooms but Wi-Fi connectivity does not reach, or it does not get all the good that is expected of it.
That is why having the option to share a Wi-Fi network directly from our Mac can be very useful on many occasions. Cases in which, for example, the workplace we occupy does not have a good Wi-Fi connection because it is very far from the router, being able to use the Mac as a router is perfect. In any case the options are there, be able to share network easily with any device is what allows this option.
