You can use your computer as a wireless hotspot. This allows other devices to connect to you without a separate network, and allows you to share an internet connection you’ve made with another interface, such as to a wired network or over the cellular network.
Open the system menu from the right side of the top bar.
Select Wi-Fi Not Connected or the name of the wireless network to which you are already connected. The Wi-Fi section of the menu will expand.
Click Wi-Fi Settings.
Press the menu button in the top-right corner of the window and select Turn On Wi-Fi Hotspot….
If you are already connected to a wireless network, you will be asked if you want to disconnect from that network. A single wireless adapter can connect to or create only one network at a time. Click Turn On to confirm.
A network name (SSID) and security key are automatically generated. The network name will be based on the name of your computer. Other devices will need this information to connect to the hotspot you’ve just created.
You can also connect to the wireless network by scanning the QR Code on your phone or tablet using the built-in camera app or a QR code scanner.
