Kernel modules live in lib/modules/$(uname -r)

Change

Load them with

modprobe ath9k

Or remove one with

modprove uvcvideo

The PC's irritating speaker beep can be really annoying. Disable it with:

modprobe -r pcspeaker

Permanently disable a module by blacklisting it in /etc/modprobe.d:

echo 'blacklist pcspkr' > /etc/modprobe.d/*nobeep*.conf

Check which kernel modules are loaded into memory:

su root
/sbin/lsmod 

Check which virtual box modules are loaded into memory

/sbin/lsmod | grep vbox 

Virtual box is using vboxpci, vboxnetadp, vboxnetflt, vboxdr.

Look at what's claiming wifi:

lshw -C network

If this shows that the device is 'unclaimed' then it's time to add a module, e.g. ath9k.

modprobe ath9k

Modules can also be 'restarted' by removing and adding them, e.g. the video module, 'uvcvideo':

rmmod uvcvideo

modprobe uvcvideo
