Other users can’t edit the network connections
If you can edit a network connection but other users on your computer can’t, you may have set the connection to be available to all users. This makes it so that everyone on the computer can connect using that connection.
Go to the Desktop and start typing Network.
Click on Network to open the panel.
இடப்புறம் உள்ள பட்டியலில் இருந்து Wi-Fi ஐ தேர்ந்தெடுக்கவும்.
Click the button to open the connection details.
Select Identity from the pane on the left.
At the bottom of the Identity panel, check the Make available to other users option to allow other users to use the network connection.
Press Apply to save the changes.
