Use nl80211

Could you give me a code sample how you would use this "nl80211"
thing, from shell?

this popped up earlier. Using shell scripts is a bad idea. However, libnl does provide python bindings. nl80211 is a netlink interface to the linux wireless kernel module.


Oh while I'm here. Is there no traditional /proc like interface
proposal for wireless information? If not, why not?

Because nl80211 is there to provide all the info.

If you do not mind reworking your shell script and want to stick to it than the answer is:

$ iw wlanX link

wlanX should be your wireless network interface.

Regards,
Arend
