Fix Recommendation

Disable all wireless network interfaces by using the following command:

$ sudo ifdown <wireless_interface_name>

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

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

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

Create and/or append a custom file under "/etc/modprobe.d/" by using the following command:

$ sudo su -c "echo install <module_name> /bin/false >> /etc/modprobe.d/stig.conf"

where <module_name> must be substituted by the actual module name.

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

$ sudo modprobe -r <module_name>
