Unable to activate WiFi p2p / WiFi Direct

Unable to activate WiFi p2p / WiFi Direct

[Kévin THIERRY]

Hi,
I've been unable to activate the p2p feature on my WiFi dongle (which
otherwise works fine). 
iwpriv command returns "wlan1 no private ioctls."
I'm running Ubuntu 12.04 with kernel 3.5.0-25 and the WiFi dongle is a
Netgear model wna1000m (driver rtl8192cu).
I've also tried with kernel 3.8.2 with the same result.
Thanks,

Kévin THIERRY

You may have more luck on the linux-wireless list.

P2P is not yet implemented in rtl8192cu. The method is being added to rtlwifi 
and the PCI-based drivers in patches that are now undergoing tests. They will 
likely be in kernel 3.10. Once that is done, I will be able to consider P2P for 
the USB-based driver.

FWIW, the use of iwpriv for things like this has been discontinued. Check the 
use of iw.

I successfully got all features to work after discovering that the wifi
dongle works out of the box on the raspberrypi 3.6.11+ with all
features.
To make it work I had to :

1) Download the latest driver source from realtek :
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true
(RTL8192CU)

2) Modify a source file as it is done here :
https://github.com/ksclarke/rtl8192cu/commit/49568f94513ce945984a8a2f27457c6278ee674d

3) Build it.

4) Unload the rtl8192cu module (rmmod rtl8192cu)

5) Load the new-built module (insmod 8192cu.ko)

Note that I did that on a x86_64 architecture with kernel 3.5.0-25 and
that I could'nt get the driver to be built with kernel 3.8.2.
