Share a Wired Internet Connection in Windows 8 and make it wi-fi hot-spot
Unfortunately, Windows 8 stripped away the graphical interface for setting up an ad-hoc network, so it’s not quite as easy to set up as it is in Windows 7 or 10. The underlying feature is still present, though. You just have to resort to a little command line trickery.
First, you’ll need to make sure your existing wireless network is shared with other network users. Press Windows+R on your keyboard to open the Run dialog box, type “ncpa.cpl”, and then hit Enter.
In the network connections window, right-click your Wireless network and select “Properties” from the context menu.
Switch over to the “Sharing” tab and enable the “Allow other network users to connect through this computer’s Internet connection” checkbox. Go ahead and clear the “Allow other network users to control or disable the shared Internet connection” checkbox while you’re at it and then click the “OK” button.
Next, you’ll need to launch the Command Prompt with administrative privileges. Right-click in the bottom left of your screen (or hit Windows+X) and then select “Command Prompt (Admin)” on the Power Users menu that appears.
With the command prompt open, your next step is to set up the wireless network using the netsh like so:
netsh wlan set hostednetwork mode=allow ssid="SSID" key="PASSWORD"
Where SSID is the name of your network and PASSWORD is the password you want users to connect with. The access point is created with WPA2-PSK (AES) encryption.
Next, you’ll start broadcasting our network with the following command:
netsh wlan start hostednetwork
And at any time, you can use this last command to show information about the connection. It lists things like the channel your connection uses, ssid name, authentication type, radio type, and the number of clients connected to your network.
netsh wlan show hostednetwork
When you’re done, you should be able to connect any Wi-Fi device to your new ad-hoc network.
