I have a VAIO Laptop running Ubuntu 12.04 (64 bit). I use a wired internet connection. I want to share this connection using my laptop's wifi as access point. How can i do this?
Click on the networking icon in the top right hand corner,and choose the Create New Wireless Network option. Enter a name for your network, choose the security you require and set up a security key (if security is enabled). Hit Create and your wireless network will be create and begin broadcasting.
This process depends on your card supporting the ad-hoc connection mode.
