Do you ever want to share internet with others, but ad-hoc makes problem with those bugs that Microsoft not much care about it?
Well, connectify solve this problem. It takes advantage of new improvement at Windows 7 to turn your laptop or PC (as long as have up-to-date wireless card) into a virtual hotspot host. Also, it supports more than 1 person to connect simultaneously to your laptop, so everyone can enjoy using internet.
Connectify still in beta stage, but I have use it for some time, and not yet discover any bug. It requires password to ON the hotspot, so put in the password. Short password normally won't work as it not allow short password. To get connectify, go here:
It's free too.
