I am using zorin OS 15.3 lite. I am having two network connections one is external network adapter and another is the inbuilt one. Since the inbuilt one is causing problems I have been using the external network adapter and I want to disable the unused network connection so that it won't show up while I click the network icon.
add blacklist (Your Wifi Adapter) to it. It may look like blacklist 3945ABG
ctrl+x to exit, y key to say yes to save, then the enter key to save as current configuration.
Reboot and test.
If it does not work, may need to adjust the intel wireless name on the blacklist. Since I do not use that card, I am not sure what the proper name should be.
