Turn Your Mac Into a Wi-Fi Hotspot
Have you ever thought about your Mac as a router? Mac computers have a special feature that makes it possible to share the internet. If your Mac has a wired connection via Ethernet, you can share it between other devices. It is similar to instant hotspot in iOS.
Activate Internet Sharing from Ethernet connection:
Click Apple logo > System Preferences > Sharing.
In the pane on the left, select Internet Sharing.
Depending on the connection that you use, choose a type of connection that you would like to share in the Share your connection from field. Be aware that you cannot be connected to a Wi-Fi and share this same connection. Other options are possible: if you are connected to the Internet through Ethernet, via Bluetooth, or tethered to an iPhone via a USB, you can choose these ways as well.
Then select the way other devices will access the hotspot, e.g. Wi-Fi.
Click Wi-Fi options to configure your hotspot. By default, the connection has no password so anyone can see your personal hotspot and connect to it. To make it visible only to you, in the Security field choose WPA2 personal, and then set up a password. You can rename your network in the same window.
When you are ready, select the Internet Sharing checkbox to open a dialog asking if you really want to share your connection. Click OK to confirm.
If you want to share a Wi-Fi connection:
As you already know, you cannot be connected to a Wi-Fi network and be a host for another Wi-Fi spot. This is due to Mac’s physical interface - it cannot do these two things at a time. However, sometimes it would be a great opportunity, and it’s possible to do if you have a USB Wi-Fi adapter or know some tips. If you travel a lot and often need to share a Wi-Fi connection between your devices, purchasing a Wi-Fi adapter will be a good idea.
If you have a Wi-Fi adapter, after plugging it in and installing, you can follow the same instruction to share this connection between your devices. You will only need to choose Wi-Fi as a source of your hotspot instead of Ethernet.
However, if you don’t feel like purchasing any additional accessories, there’s another way out - creating a Bluetooth PAN and sharing the Internet connection via Bluetooth. It will be slower than ordinary Wi-Fi or shared from Ethernet, because it will use Bluetooth to access the connection, and some devices may not be compatible. However, you don’t need any investments for this method. If this is acceptable for you, follow the same setup process, just make sure that you select Bluetooth PAN in the “To computers using” box.
Internet connection is something that we use and need almost every day. This is an important and sometimes the only way to stay in touch with your family and friends, especially if you travel abroad. These tips will help you to always have access to the Internet on all your devices.
