Ubuntu: Ubuntu 14.04: How do I disable Realtek RTL8192E/RTL8192SE wifi driver?


How do I disable my Realtek wifi driver? It makes my laptop freeze when connected. To work around the problem, I got a USB wifi adapter. Problem is, the Realtek driver still connects to the network and I have to manually disconnect it. I tried to blacklist it, but I obviously didn't do it right. Here is a screenshot of my network connections (the Realtek and the wifi adaptor are both higlhlighted in yellow):


My specs are also listed here: http://paste.ubuntu.com/26050614/

I'm a newbie and confused!! Your help will be greatly appreciated on this one! Thanks!!


your laptop should have a button that disables wifi; its usually on its front or right sides; might be on top near the screen; it also might have a marked combination on keyboard.. look for an stylized antenna mark

also you can right click you network icon and edit(delete) the problematic wlan connection so it would not autoconnect

considering this article


as root

lsmod //lists the modules; search for something realtek related

modinfo -F depends [module name] //to see if it has modules that depend on it

nano /etc/modprobe.d/blacklist.conf

and add > blacklist [module name] //if it has other modules depending on it it will not be blocked

or add > install usbcore /bin/true //which will block the module and dependencies

save and exit nano

update-initramfs -u



The option to blacklist that driver is the right thing to have done, the other option would be to remove it but this should be a last resort after all else. I suggest you just blacklist and to blacklist that driver simple do:

echo "blacklist rtl8192se" >> /etc/modprobe.d/blacklist.conf  

Then reboot and run: dmesg | grep 819 or lsmod | grep 819 to make sure its no more loading.


Thanks everybody for all your help. I just learned a whole bunch that I wasn't aware of by reading your posts.

The answer for me was to identify and blacklist the offending module which it turns out was r8192e_pci and not other ones I had previously added to the blacklist.conf file (the hardest part for me in the end was to properly identify the module that I didn't want loading).

Even though it has rtllib as a dependency, doing 'blacklist r8192e_pci' appears to be enough to stop it from loading.

I should add that post #14 from Chili555 also helped me figure things out. https://ubuntuforums.org/showthread.php?t=1826243&page=2
