While setting up a WiFi hotspot & sharing your active internet connection in Windows you may have faced an error which displays “Error 765: internet sharing cannot be enabled. A LAN connection is already configured with the IP address that is required for automatic IP addressing“.

Well, this is caused because the hosted network is unable to obtain the IP Address and Subnet mask automatically. So we can easily fix this by adding IP Address and Subnet Mask manually.

Steps to fix a Lan Connection is Already Configured with IP Address Problem

  • First of all, start your hosted network connection.  Open command prompt and type the following command to start the hotspot connection: netsh wlan start hostednetwork
  • Once the connection has been established, open Control Panel, go to Network and Sharing Center and then Click on your hosted network connection as shown below:

  • Now select Use the following IP Address and add the following values: 

       IP Address: 192.168.137.1
