How To Set Up Wireless Ad Hoc Internet Connection In Windows 8

Step 1: Launch an elevated command prompt under Windows 8 (one with administrator privileges).
Step 2: Run the following command to verify that your network interface supports virtualization:

netsh wlan show drivers

If Hosted network supported says Yes, you’re all set. Otherwise, you need to upgrade your hardware, if the software update doesn’t fix it.
Step 3: Now, set up the ad hoc wireless network using this command. Replace the parts in markup tags with your own choices

netsh wlan set hostednetwork mode=allow ssid= key=

Step 4: Until now, your hosted network has been created. Now, you need to start it. Use the command below:

netsh wlan start hostednetwork

Step 5: You’re all set, with just one thing remaining. If it’s not already enabled, you need to allow Internet Connection Sharing (ICS) for your currently-active internet connection. Simply head over to Network & Sharing Center, and in the properties for the current internet connection, enable ICS. Make sure to select the ad hoc connection under Home networking connection.
