In Windows 8.1, you will not find GUI settings for setting up a wireless ad hoc network as you see in Windows 7 but it is pretty easy to create it.
If you were looking for setting up of router to share network without installing third-party software, then you are at right place.
So let start…
Open the Command Prompt (CMD) as an Administrator.
Search for ‘cmd’ in Start Menu (You can open Start Menu only if you have updated 8.1)and then Right Click on it and Select “Run as Administrator” from the menu.
Or here is a shortcut to do so.
(Press Windows key + X + A)
Type in the following command to ensure that your network interface supports Hosted Network feature:
netsh wlan show drivers
Your Hosted network supported should have value “Yes”. If it is “NO” then you have to update your wireless driver.
If the updated driver still does not help, then you might need to upgrade your hardware.
Now, let us proceed further. We will now configure your Ad Hoc Wireless connection.
Type in CMD this command:
netsh wlan set hostednetwork mode=allow ssid=<your desired network name> key=<your password>
Next, you need to start the hosted network. Type in CMD the command below:
netsh wlan start hostednetwork
Navigate to Control Panel > Network and Sharing Center. Click on “Change adapter settings”.
Right-click on Wi-Fi adapter > select Properties
Head to “Sharing” tab > check the box Allow other network users to connect through this computer’s Internet connection > Click on OK button.
You just created your own hosted-network and now you can share your data or internet connection with all other gadgets using this ad hoc wireless network.
