Adhoc is the older wireless connection technology, with limited distances, and sometimes a failure to connect, and many new Android systems (MX2 Systems) have started to cut off the old technical support, while at Windows 8 The GUI interface is no longer available to provide adhoc creation.
But fortunately, Windows 8 did not cut him down directly, we can still use the command line to open it.
The following references are from the MVP Xu Xian for reference only:
win+x, select command Prompt (Administrator).
enter "netsh wlan show drivers" to
see "Supported Hosting Networks" if it is "yes" to start the wireless hotspot feature.
Enter the Netsh wlan set hostednetwork mode=allow ssid=win8adhoc key=12345678,
where Win8adhoc is a network name, customizable, 12345678 is a password, Customizable, at least 8 bits.
then enter "netsh wlan start hostednetwork" to start the wireless hotspot and enter "netsh wlan stop hostednetwork" to close
