I have a laptop with Ubuntu and connected to internet through cable. I want to set up an ad-hoc network to share the internet connection via wi-fi. The other computer runs on Windows Vista.

I managed to do this in Windows 7, but I can't do it in Ubuntu.

This Ubuntu wiki page explains everything.

It actually does not explain how to share the internet connection through the wireless card. However I already solved the problem, but only with WEP security. – miguelSantirso Aug 26 '10 at 15:37
Sorry, I thought it is obvious that after connection is estabilished, WiFi card is behaving like the Ethernet one. – whitequark Aug 26 '10 at 17:27
