If your PC is equipped for capturing wireless networks, with Connectify you can convert it into a repeater, ie, into a Wi-Fi access point for other devices, as if it were the same router.
Once other devices are connected to the Wi-Fi from your PC, with Connectify you can transfer files very easily. In addition, Connectify is ready to share the Wi-Fi 3G and 4G networks. Of course, you can control the functions of the firewall for maximum security.
Obviously, the functions of Connectify Lite are limited with respect to those of Connectify Pro, the complete program that requires payment of a license. But with Connectify Lite you can get an idea of ??the features in this interesting program.
NOTE: from Windows XP, Connectify requires the installation of Service Pack 3 or later.
