Hi Vaibhaw,
Thank you for posting your query on Microsoft Community forums.
- Is your computer connected to a Homegroup?
- Are you trying to create a hotspot?
Generally, this happens if the "Allow the computer to turn off the device to save power" power option for the wireless network adapter is cleared. So, I would suggest you to refer to the following methods and check if the issue persists.
Method 1:
Refer to the steps provided in the following link to change power management settings for network adapters and check if it helps.
If the issue still exists, try the next method.
Method 2:
You should first enable internet connection sharing or ICS on its wireless adapter and run the command.
Step 1:
a. Click Start, click Control Panel and open Network and Sharing Center.
b. In the Network Connections view that appears, right-click on your Wi-Fi adapter and choose Properties. Then, navigate to the Sharing pane and check the option titled Allow other network users to connect through this computer’s Internet connection. If it’s checked, you might also uncheck the option titled Allow other network users to disable the shared Internet connection.
c. When you click OK, the window will close and a new network connection, named Wireless Network Connection 2 (or similar), will be created in Network Connections. Right-click this connection and choose Enable.
Step 2:
Now it’s time to turn to the command prompt. You’ll need administrative privileges, so go to Start Screen, type cmd (but don’t tap Enter), right-click the cmd entry in the search results list, and choose Run as Administrator. Then, in the command prompt that appears, type the following command:
netsh wlan set hostednetwork mode=allow ssid=GeeksAndTweaks.com key=abcd1234
You’ll want to replace the SSID and key with values that appropriate for the network you wish to create. Note that the key must be at least 8 characters long.
Now, you must start the wireless hosted network with the following command:
netsh wlan start hostednetwork
To test that you’ve properly create a functioning wireless hosted network, use another PC (or a Wi-Fi-based device) to look for, and connect to, the new network.
