Fix Recommendation

List all the wireless interfaces with the following command:

$ ls -L -d /sys/class/net/*/wireless | xargs dirname | xargs basename

For each interface, configure the system to disable wireless network interfaces with the following command:

$ sudo ifdown <interface name>

For each interface listed, find their respective module with the following command:

$ basename $(readlink -f /sys/class/net/<interface name>/device/driver)

where <interface name> must be substituted by the actual interface name.

Create a file in the "/etc/modprobe.d" directory and for each module, add the following line:

install <module name> /bin/true

For each module from the system, execute the following command to remove it:

$ sudo modprobe -r <module name>
