Hello everyone,

I have been using Gentoo for quite some time on this netbook and i'm very satisfied about it. After using the command line tools and scripts for some time to connect my wireless, I decided to start using NetworkManager, and I've been using that for a while, haven't had any problems with that up to now.

However, just today i wanted to use the command line tools (i wanted to use Aircrack-ng actually) and i find out my "sudo iwconfig" output is empty, although i am connected to a wireless network:
james@Netbukkolo ~ $ sudo iwconfig
wlan0     no wireless extensions.

lo        no wireless extensions.

The network works fine as i am typing this now. However none of the command line tools will work at all, no matter if i kill NetworkManager or not, and no matter if i start up without it. I've also tried loading and reloading the device driver (ath5k) with no results.

I really don't understand what could make iwconfig's output be empty when everything is working fine. I am using the latest wireless-tools package, 30pre9, but i tried to downgrade to package version 29 and it still shows the problem.

I have a Linux Mint install on this netbook, and it works fine, with also iwconfig showing its correct output.

You don't have wext compatibility (CONFIG_CFG80211_WEXT) in your kernel. Either enable that, or use more modern tools, specifically net-wireless/iw

Oh yes indeed, i don't have that option set! I had deselected it during the last kernel compile, as the helper text said:
  Enable this option if you need old userspace for wireless extensions with cfg80211-based drivers.     

I just didn't think the latest wireless-tools still needed that "old userspace" option, since i was running a full ~x86 system. I should be more careful in the future :) Thanks!
