I currently have a problem with Wireless LAN on Linux Mint 17.1.
I can't enable WLAN, when trying to enable it, it disables immediately.
Here some commands which I already tried out and found by googling myself around.
$ lspci -nn | grep "Network controller" 02:00.0 Network controller : Intel Corporation Centrino Advanced-N 6200 [8086:422c] (rev 35)
I then found out that the correspondig driver I is
$ rfkill list ... 3. phy0: Wireless LAN Soft blocked: no Hard blocked: yes
As far as I read, Hard blocked means, that my WLAN hardware switch is turned off. But when I play around with the corresponding key (fn+f8) then only the
Soft blocked value changes.
In one thread I found that when I execute
$ modinfo ath5k | grep "nohwcrypt" parm: nohwcrypt:Disable hardware encryption. (bool)
then I should try executing
$ sudo modprobe ath5k nohwcrypt
though I don't really what this does and it did not change anything.
In the BIOS the Wireless LAN is enabled and Windows was installed before and there it worked as well so I don't think that the hardware is not working and it is a software problem.
Does anybody know how to proceed?
