Here I'll show you how to configure your laptop/pc and your android device to reverse tether Internet using wifi adhoc networks.
It's working fine for me on my samsung galaxy y and i can download from google play ..
First open the dos command Prompt by typing cmd on the run command or directly on the start menu...type these commands to create an ad hoc network :
1/ netsh wlan set hostednetwork mode=allow ssid=NAME key=PASSWORD
2/ netsh wlan start hostednetwork
(NAME is the name of the ad hoc network, you can change it...PASSWORD is your adhoc password, change it to a more secure one...)
To stop the adhoc network , type this command : netsh wlan stop hostednetwork
Now, to configure IP addresses, follow these instructions:
Step1 : Configuring laptop/pc :
1- open network and sharing center on control panel then change adapter settings.
Right click on your internet network and click on properties then select the tab sharing and check the "allow other network users to connect through this computer's internet connection" (choose Local Area Connection* 11 ).
check also the "allow other network users to control or disable the shared internet connection"
next click on setting and check all items...
2- Right click on Local Area Connection* 11 and double click on "internet protocol version 4(tcp/ipv4)"
on the new window select "use the following ip address" : 192.168.137.1
and subnet mask 255.255.255.0
Step 2 : Configuring the android device :
Now, we will configure the android device to make it able to access this new adhoc network
Go to setting on the menu of your device
then wireless and networks then wi-fi settings then activate wi-fi .
Right click and choose advanced .
Check the "Use static IP"and fill in :
ip address: 192.168.137.5 (for example)
Gateway : 192.168.137.1
Netmask : 255.255.255.0
DNS 1: 192.168.137.1
DNS 2 : 192.168.137.1 (Optional)
then right click and save.
Finally, click on the adhoc network (and input password ) then connect.
And that's all ...enjoy internet with Google Play download supported...
( It's important to consider that some Android devices should be rooted to make internet via adhoc working)
If you encounter problems connecting ,try to disable then to reactivate wifi, else reboot your android device.
