Android Phone Using WiFi, can Share Internet Connection of a PC

WiFi Ad-Hoc Networking is a popular method to share internet connection between  computers (pc or laptop) or between a computer and a smartphone that has built in WiFi. Unfortunately, this method of networking is not supported by Android since it was released until the time of this writting. One of the popular method to enable ad hoc mode on Android devices is by  changing a WiFi configuration file located on /system/etc directory called tiwlan.ini. But this method is specific to phone’s WiFi chipset and you need root access to change the file. The tiwlan.ini is a configuration file for Texas Instruments WiFi chipset (e.g HTC dream) so you will not find it on Samsung Spica that use Broadcom WiFi chipset.

Another alternative method is by using a software based virtual access point that using Windows 7’s Wireless Hosted Network technology. This method only runs on Windows 7 and hardware specific. Currently i found two best virtual access point softwares, Virtual Router and Connectify. They both operate in the same maner and very easy to use. I have tested both of them to share internet connection from my PC that used  Sierra Wireless USBConnect 881 modem for internet access and an external TP-Link TL-WN31G Wireless USB adapter with my Samsung Spica.

Here is the guide on how to use virtual router and connectify

On Windows 7 Box:

   -  Download and install Virtual Router or Connectify, you can try one of them. They are hardware specific so read the documentation on their websites about the supported WiFi devices.
