Creating an ad hoc network in Windows 8.1
On Windows 8 and 8.1, you can host a wireless network so that multiple PCs can play a LAN game or share files. Open a new command prompt as administrator:
netsh wlan set hostednetwork mode=allow ssid=MyWirelessNetwork key=MyWirelessNetworkPassword1111
netsh wlan start hostednetwork
Then when you want to stop sharing
netsh wlan stop hostednetwork
Simple!
