Can't afford to buy a wifi router? You dont need to buy one at all. As long as you have Windows 7 operating system running on your pc or laptop you can turn your device into a wi-fi router. And forget about the hassle set ups of opening the control panel, clicking this or that. Just install one program and you are ready to go wireless without a router.
I just installed this application on a Windows 7 Laptop and am now able to connect my PDA phone and tablet to the laptop without a router. Yes it is cool and it saves a lot of money. The program is called "Connectify".
Connectify is an easy to use software router for Windows 7 computers. After downloading and installing the lightweight application, Connectify utilizes your computers' built in Wi-Fi card to wirelessly share any available 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 Connectify hotspot just like any other Wi-Fi access point and are kept safe and secure by password-protected WPA2 Encryption.
Connectify is only less than 3MB to download. You can get this amazing program here: http://connectify.me/
Just run the easy setup wizard to get started. Then enjoy!
