Here is an easier alternative to the android - pc connections [adhoc] and share internet, without doing anything on the device, only with a PC application, for all androids and devices...
We will turn our PC into a router, well, do it this way.
This is easy with a little application that I share.
1. Download and extract the files
2. Install the application
3. Restart the system
4. Register the product with the serial (included)
5. Setting fields:
Hotspot Name: choose any name
Password: choose any password
Internet to share: Your interface with internet to share
Share Over: Your wifi interface to connect with your android
Sharing Mode: Select the "wi-fi Access Point"
6. Start Hotspot
7. Activate the wifi on your android and connect to your acces point
