mHotspot lets you create a secure wireless hotspot for sharing the Internet. Thus, a LAN, 3G, or other Internet source could be shared among other laptops or mobile devices. The program interface is simple and anyone can use it. You have the option of setting the maximum number of clients that can connect to your network.
Be careful while installing the program, since the download is provided only through 3rd party hosting sites - a lot of unwanted programs may get installed.
