next in thread | raw e-mail | index | archive | help
Hello.
I installed FreeBSD-current on my laptop recently, machine used to run
7.1 without problems, and worked flawlessly with my AP using WPA2+PSK.
The PC is a Dell inspiron 8600 laptop with an intel 2100 wifi card (ipw
driver). The AP I'm trying to connect to has ssid "LILLIPUT".
After installing current I modified my configuration for the new wlan
interface cloning order and tried to associate as usual, but am now
getting errors in the preauth phase and wpa_supplicant just loops around
the problem.
This is the debugging output from WPA supplicant (it's a bit long, I
know...)

I indented the error messages.
here are the relevant configurations, wpa_supplicant.conf:
ap_scan=1

psk="secret"
}
and excerpt from rc.conf:
wlans_ipw0="wlan0"
create_args_wlan0="wlanmode sta country IT"
ifconfig_wlan0="WPA DHCP"
I dug around the sources and tried modifying the file
src/contrib/wpa/src/rsn_supp/preauth.c, in the function
rsn_preauth_scan_results to return true for the last argument of
pmksa_candidate_add, but it just gives me another error about not being
in the correct state for pre-auth.
I don't know much about the internals of wifi security or adapters, so I
could not try much more, and google was of very little help.
I don't really know what the problem is, but what looks strange to me is
that this same PC was working fine with this same AP and same config
with 7.1.
Anyone has some pointers for what to look at? Does this need debugging?
Thanks to anyone willing to help!
