Re: Ubuntu 14.04 and the intel 3160 chip monitor mode support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi again,

Emmanuel just told me that on 3.13 the monitor mode is not supported. 
 You can try to disable power saving, by loading the iwlmvm module with
power_scheme=1 (it's a module parameter) and check if you have any
better luck.

If not, try to upgrade your kernel. :) Apparently Ubuntu LTS 14.04 also
provides a 3.19 version of the kernel (from Ubuntu 15.04).  Take a look
at the following page:

https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes#Updated_Packages

HTH!

Cheers,
Luca.
