To work with modules you could use these commands:
List modules loaded in the kernel:
$ lsmod
List correlations:
$ lsmod | grep <MODULE>
Remove module:
# rmmod
Probe module (Works until the next reboot):
# modprobe
Remove the module in probe:
# modprobe -r
Load the module to the kernel (Install):
# insmod
$ man <COMMAND>
Module related directories under /etc/:
modprobe.d/     modules         modules-load.d/
Locating Module directories (For example, in a i686 computer):
$ locate uvcvideo
/lib/modules/3.16.0-4-686-pae/kernel/drivers/media/usb/uvc/uvcvideo.ko
/usr/include/linux/uvcvideo.h
/usr/src/linux-headers-3.16.0-4-common/include/uapi/linux/uvcvideo.h
To install other Wi-Fi cards you could require to work on other directories like: /etc/modules, /proc/modules, /lib/firmware, /usr/bin and /usr
