Access Point on a laptop. Windows
To change your laptop into a wireless network router can use the software Connectify. Software works with a router Windows 7 and allows you to share a wireless network to other devices that are able to connect to networks secured WEP, WPA and WPA2.
It is worth noting that Connectify can wirelessly share an Internet connection, not only “the cable” is also a wireless network, which is connected to a laptop. (if video displays some error, play it in youtube by double click on video, as youtube is upgrading to HTML5)
The application is advertised by the manufacturer as way to save. You go to the cafe, which offers paid Wi-Fi. Hook up your laptop … and you can share the connection through Connectify your friends.
Ethically can not be too nuanced business model, but in the end can be used to Connectify Internet access only within their devices, such as those that do not support a strong WPA2 encryption used by the HotSpot in range which we dwell. Then, using Connectify change to a weaker encryption protocol and advertises the network to the mobile phone according to schedule.
