Linux Disable Wireless Networking ( Wi-Fi )

To disable wireless networking (Wi-Fi) in Linux, you can use the nmcli command. This command allows you to manage Network Manager, which is a service that handles networking in most modern Linux distributions.

To disable Wi-Fi using nmcli, follow these steps:

1. Open a terminal window.

2. Use the nmcli command to turn off the Wi-Fi interface:

nmcli radio wifi off

This will disable the Wi-Fi interface and turn off the wireless radio.

3. To verify that the Wi-Fi interface has been disabled, use the nmcli command with the device option:

nmcli device

This will list all available network devices, along with their status. The Wi-Fi interface should be listed as "unavailable".

To re-enable the Wi-Fi interface, use the nmcli command to turn the wireless radio back on:

nmcli radio wifi on

This will enable the Wi-Fi interface and turn on the wireless radio.

Note that the nmcli command requires root privileges, so you may need to use the sudo command to execute it.
