The Network Shell (netsh) utility is basically developed to let users configure network devices in both client and server editions of Windows. The support for configuring WLAN using netsh was first introduced in Windows Vista, and it’s now available in Windows Server 2008, Windows 7 and Windows 8. Using netsh wlan command, one can easily use hosted network (virtualization) feature to create a virtual wireless connection. The Hosted Network is WLAN feature, which is designed to implement virtualization of physical network adapter. Since it plays a vital role in creating a virtual wireless adapter, it’s used by a majority of virtual Wi-Fi hotspot applications, such as Virtual WiFi Router, MyPublicWiFi, Marfi etc. So, if your NIC supports wireless hostednetwork / virtualization feature, then you can create an ad hoc wireless connection and turn your PC into Wi-Fi hotspot.
As stated earlier, both Windows 7 and Windows 8 natively support configuring ad hoc wireless connection using the netsh commands. In order to create an ad hoc connection in Windows 8 using netsh utility, run CMD with administrative privileges’; just type cmd on Start Screen, right-click it and select Run as administrator.
Now, first you need to check weather your network interface supports virtualization or not. Simply, run the following command to view Hosted network supported status.
netsh wlan show drivers
In case, it says No, you will need to update your network adapter’s driver. If your NIC supports virtualization, you’re good to go. Now, enter the following commands to configure an ad hoc wireless connection.
netsh wlan set hostednetwork mode=allow ssid=<network name> key=<passkey>
Once the hosted network has been set to allow, you need to start the mode to create an ad hoc connection. Just enter the command below.
netsh wlan start hostednetwork
If it says “hosted network couldn’t started”, you need to disable current wireless network device and then enable it. You may also need to refresh network adapter list from Device Manger to install a virtual network device driver.
When the hosted network is started, enable ICS for newly created Wi-Fi connection, so that you can share your internet connection with others. In order to enable ICS feature, head over to Network and Internet –> Network Connections, and open Properties dialog of network device (which is connected to internet). Now, open Sharing tab, enable Allow other network users to connect through this computer’s Internet connection, and then choose the newly created ad hoc connection from the list. In our case, it’s Wi-Fi 2, as shown in the screenshot below.
Once the internet connection is shared, check the IP address assigned to newly created ad hoc connection from TCP/IPv4 Properties. If it doesn’t assign IP address, then run netsh wlan start hostednetwork command in CMD
After following the above steps, you will be able to connect Wi-Fi enabled devices with your Windows 8 PC. As shown in the screenshot below, the current internet connection is successfully shared with ad hoc connection.
