I just did a new Gentoo install on my new laptop. Using the wiki doc for wifi, I copied over the wpa_supplicant from /usr/share/* to /etc/wpa_supplicant.

wpa_supplicant did not like the default config and errored out.

Does anyone have wpa_supplicant.conf that uses the nl80211? Not sure how to make it use the nl80211 driver and it defaults to WEXT.

Also, I start wpa_supplicant with the SysVinit script.

You can use the -D switch eg.
Code:
wpa_supplicant -Dnl80211 -i<interface>

From wpa_supplicant(8)
Quote:

-D driver
Driver to use (can be multiple drivers: nl80211,wext).

No, where in the wpa_supplicant.conf do I tell it to use a driver? I am not starting this from command line, but from the init script.

AFAIK there isn't such an option, at least I wasn't able to find anything in wpa_supplicant.conf(5).
But even if you invoke wpa_supplicant trough script you can pass it -Dnl80211.

You mean /etc/init.d/wpa_supplicant start?
Then make sure /etc/net.* scripts are not running or better, do not even exist. It's all described in the wiki article. One setup for netifrc, another for dhcpcd. Do not mix them!!!

dman777 ... use the supplied "openrc" config:

/etc/conf.d/wpa_supplicant:
wpa_supplicant_args="-Dnl80211"

or, if you were using netifrc, you could do the following:

/etc/conf.d/net:
wpa_supplicant_wlan0="-Dnl80211"

Note, you might also want to pass '-qq' and so suppress debugging (at least for normal use).

wpa_supplicant should already default to nl80211, unless you've gone out of your way to edit the order the drivers are listed (in wpa_supplicant -h).

Ant P. ... those (in 'wpa_supplicant -h') seem to be hardcoded, I build wpa_supplicant without DRIVER_WEXT and DRIVER_WIRED yet they are listed as 'drivers'. Otherwise, you're probably right, but I'm not 100% sure, as I don't know how/if wpa_supplicant detects if a link is wired, or has wireless extentions, etc.

You could/can do the following: '-Dnl80211,wext' ... which suggests it falling back, and I would expect that nl80211 be the first it try when no '-D<driver>' is provided, at least given WEXT depreciation. Still, it probably doesn't hurt to be explict, and I wonder if the OP isn't seeing something that is perhaps caused by a misconfigured CFG80211/NL80211, or if in fact nl80211 is in use regardless.
