 Posted: Fri Dec 22, 2017 4:00 pm Post subject: wpa_supplicant.conf that uses the nl80211? |
 |
|
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. |

See https://wiki.gentoo.org/wiki/Wpa_supplicant#Global

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.
