I use HTC Explorer and I have created an ad-hoc network on my laptop. Although other laptops are easily able to connect to it, my mobile device is not even detecting the Wi-Fi.
How can I connect my mobile to the Wi-Fi hotspot on my laptop (running Windows 7)?
There is an alternative solution involving "Microsoft Virtual WiFi Miniport Adapter":
netsh wlan set hostednetwork mode=allow ssid=NAME key=PASSWORD
netsh wlan stop hostednetwork
netsh wlan start hostednetwork
