My wireless adapter (atheros) will not work - I've tried extensive troubleshooting with @danatela (bless his/her heart) here:

Wireless not working - ASUS X450J - Qualcomm Atheros

but it failed. Other answered questions refer to this post on crunchbang

But I have no idea how to create a file in this directory - I don't have permissions?

Please open a terminal and do:

gksudo gedit /etc/modprobe.d/ath9k.conf

The text editor gedit will open a new empty file. Add a single line:

options ath9k nohwcrypt=1

Proofread, save and close gedit. Now load the module immediately:

sudo modprobe -r ath9k
sudo modprobe ath9k nohwcrypt=1

The conf file you wrote will cause the parameter nohwcrypt=1 to now be automatically be loaded on boot.

  • What does "load the module" mean? – ConnorJ Mar 28 '14 at 10:47
  • It means that you want the driver ath9k to be loaded into the system but with a driver parameter nohwcrypt=1. Ordinarily, after you have written the conf file, it will only be applied on boot. By unloading ath9k and reloading it with nohwcrypt=1 immediately, there is no need to reboot to apply and test it. – chili555 Mar 28 '14 at 11:34
  • Is nohwcrypt=1 really necessary in sudo modprobe ath9k nohwcrypt=1 ? Shouldn't the config file be read with sudo modprobe ath9k where that option already exists ? – Sergiy Kolodyazhnyy Mar 11 '19 at 01:27
  • @SergiyKolodyazhnyy Not strictly, but it can't hurt. – chili555 Mar 11 '19 at 21:22

What you have to do is open your file browser with root (administrator) privaledges. To do this, open terminal (ctrl+alt+t), and type:

gksudo nautilus

This will open a file manager, you can do all the file managing you need to do (do not close terminal until you have closed the file manager).

WARNING Running programs with sudo can be dangerious. It basically gives them access to all of your computer. Do not open just any program with sudo!

EDIT: The old answer said to run 'sudo nautilus' This is not a good idea according to here! Whenever running graphical applications with sudo, use gksudo or kdesudo instead of sudo(see the link for more details).
