I attempted to configure my wireless card using wpa_supplicant -Dwext (as had worked with this card in my prior installation), but neither that nor iwconfig work with my new (January 5, 2013) installation.
wpa_supplicant -Dnl80211 works, and I can get status information with the 'iw' tool, but neither the necessary driver nor the tool are mentioned in the installation docs, and I spent quite a long time searching before stumbling on my solution.
I tried the linux-3.6.11-gentoo or linux-3.7.1-gentoo kernels.
the network card uses the rt2800pci module
03:00.0 Network controller : Ralink corp. RT2790 Wireless 802.11n 1T/2R PCIe [1814:0781]
Steps to Reproduce:
1. Follow handbook installation guide
2. Configure kernel and load module for wireless card
3. install wireless-tools and wpa_supplicant
4. configure /etc/wpa_supplicant/wpa_supplicant.conf to use wext driver (as per previous installation)
5. try iwconfig
iwconfig gives the message "wlan0 no wireless extensions.",
when attempting '/etc/init.d/net.wlan0 start' I get IOCTL errors followed by a 'network inactive' message
a working connection and some useful status information from iwconfig
I don't think this is a documentation problem per se, but rather a regression in the kernels or applications?
I don't think we tell users that they should use wext (we have one example in the instructions, using madwifi, and with the comment that we definitely need to give the right one). Imo, this isn't a documentation bug, nor something Gentoo related.
