Maryfi is a free and easy to use software router for Windows 7 computers. With Maryfi, users can wirelessly share any Internet connection: a cable modem, a cellular card, or even another Wi-Fi network.
Other Wi-Fi enabled devices including laptops, smart phones, music players, and gaming systems can see and join your Maryfi hotspot just like any other Wi-Fi access point and are kept safe and secure by password-protected WPA2 Encryption.
Maryfi can easily act as a repeater for your home router, extending its range and providing Internet access wherever you need it. Connect to your home network, apply sharing settings to your home network, enter the same Wi-Fi name and password, and hit "Start Hotspot." Devices will automatically connect to the Internet through either your Maryfi hotspot or home router depending on proximity. you can finally have Internet access in that impossible back room or basement. In addition, if you run Maryfi away from home with these settings, any devices that need to be bound to a specific network (such as Eye-Fi cards or wireless printers) will work flawlessly with no additional configuration no matter where you are!
