I use Connectify on Windows 7 to create a Wi-Fi hotspot so I can share my Internet connection on my laptop with others. I did some search trying to find an alternative for Ubuntu, but I didn't find any one easy solution. Sure I found some complicated methods to do that but they all need a networking expert to understand and apply as they require several pieces of software to install and configure .. etc.

Did I miss something? Is there any easy-to-apply solution to turn my Ubuntu laptop into a Wi-Fi hotspot?
