Maybe you have an old computer and want to convert it into a virtual router that you can control. Maybe you just need a Wi-Fi hotspot for your tablet and mobile phone in a conference hotel room where the wired network is fine but the hotel-provided Wi-Fi is crap. This tutorial will help you configure your Ubuntu MATE 10.06 laptop as a Wi-Fi access point or hotspot.
Now you can re-enable your laptop's Wi-Fi. You should not have to re-start your computer. The network connection you did not configure should connect to the network/Internet as normal. The Wi-Fi connection that you did configure will be broadcasting its SSID, ready for your tablet, mobile phone or other device to connect. From your mobile device, search for your new Wi-Fi access point using the name (SSID) you chose in the setup. Connect as you would to any Wi-Fi router or hotspot. (Note: I have NOT tested connecting to the hotspot with more than one device, but I believe it should work.)
This works with other Ubuntu derivatives as well.
