If you want to share internet through wireless connection, you must be connected to a wired connection. You can not share a Wi-Fi - when you make a Wi-Fi hotspot, you will be disconnected from your current wireless network.

To create a hotspot, select the wireless network and click the Use as Hotspot at the bottom of the window.

After you click Create a Hotspot, you will see a pop up notification that your laptop's wireless radio show is now used as an ad-hoc access point. You should be able to connect from another device using the default network name - "ubuntu" - and the security lock displayed in the Network window. However, you can also click the Options button to customize your wireless hotspot.

Of the wireless tab, you can assign a custom name for your wireless network using the SSID field. You can also change the wireless settings other than here.
