hostapd & windows-clients

[tuhoaja]

Hi

I'm trying to setup

FreeBSD 8.2-RC2 FreeBSD 8.2-RC2 #0: Wed Jan 12 17:26:33 UTC 2011     root@almeida.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  i386

as a wireless access point for my computers. I have ath0, where i have configured wlan0 to access internet and wlan1 to act as an access point.
In rc.conf i have

wlans_ath0="wlan0 wlan1"
create_args_wlan0="mode 11g country Finland"
create_args_wlan1="wlanmode hostap mode 11g country Finland"
ifconfig_wlan0="WPA inet <my ip> netmask 255.255.255.0"
ifconfig_wlan1="inet 192.168.0.1 netmask 255.255.255.0 channel 11"

and hostapd.conf as

interface=wlan1
driver=bsd
debug=11
ctrl_interface=/var/run/hostapd
ctrl_interface_group=wheel
#country_code=FI
#dtim_period=2
ssid=freebsdap
wpa=2
wpa_passphrase=<my_secret_password>
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP

Well it works, kindof. With my iPad it connects just fine and gets ip from my DHCP-server, no problem, i can surf the web and do whatever I do. But when I try to use it with my Windows XP or Windows 7 laptops, it does not work.

With wlandebug I managed to get the following output, repeated all over again:

Jan 19 07:15:22 reming kernel: wlan1: [00:0e:9b:ae:d7:6f] recv auth frame with algorithm 0 seq 1

Jan 19 07:15:25 reming kernel: wlan1: [00:0e:9b:ae:d7:6f] station with aid 1 leaves

It seems to authenticate just fine, but then bail out for some reason.

Anyone have any idea what to do or how to fix this? Do I need some special configuration for windows-machines? Any ideas how to debug this further?

Try running hostapd by hand and add one or more '-d' options to turn on debugging. See if that gives any clues.

I did some changes, in rc.conf:

ifconfig_wlan1="-bgscan inet 192.168.0.1 netmask 255.255.255.0 channel 11"

And in hostapd.conf:

preamble=1
wpa_pairwise=CCMP
wpa_gmk_rekey=600

Now it seems that all the clients can connect, but the connection seems to drop every now and then(restarting hostapd helps on this).
I think I'll let it run for a while and try to debug the situation.
