Another method to disable wireless networking in Ubuntu is via the command line:

1. Open a terminal by pressing Ctrl + Alt + T.
2. Run the following command to list the available network interfaces:

1

ip link show

Look for the wireless interface, typically named wlan0 or something similar.

1. Run the following command to disable the wireless interface (replace wlan0 with your actual wireless interface name if different):

1

sudo ip link set wlan0 down

This command will disable the wireless network interface.

1. To re-enable the wireless interface, run the following command:

1

sudo ip link set wlan0 up

This will bring the wireless interface back up and allow you to connect to wireless networks again.

Using either of these methods should successfully disable wireless networking in Ubuntu.
