[TriLUG] having trouble getting wpa setup

[Nick Goldwater]

I posted this earlier:



#You may want to try wpa_supplicant and remove all the other network managers. I have also found that 'iwpriv athx bgscan 0' works well with #cisco ap's.
#
#Ex: wpa_supplicant.conf
#
#ap_scan=1
#
#network={
#        scan_ssid=1
#        ssid="your id"
#        proto=WPA RSN
#        key_mgmt=WPA-PSK
#        pairwise=CCMP TKIP
#        group=CCMP TKIP
#        priority=your integer here
#        psk=your hash here
#}

The reason for the iwpriv is to deal with multiple ap signals with the same ssid. 

Here is my /etc/network/interfaces

auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0
auto ath0
iface ath0 inet dhcp
pre-up wpa_supplicant -Bw -Dnadwifi -iath0 -c/etc/wpa_supplicant.conf
post-down killall -q qpa_supplicant
iface eth0 inet dhcp
auto eth0

laptop:~# lsmod | grep wlan
wlan_wep                7040  1
wlan_scan_sta          13696  1
wlan                  203076  5 wlan_wep,wlan_scan_sta,ath_rate_sample,ath_pci


I'm running Linux version 2.6.20-16-386 (root at terranova) (gcc version 4.1.2 (Ubuntu 4.1.2-0ubuntu4)) #2 Thu Jun 7 20:16:13 UTC 2007

the "might" is the problem :-)

Ah that's one way of finding if my cards work. Presumably I 
can watch the logs too.

don't have any wpa networks around, which is another 
problem.

ahem, my bad, you're correct - the link layer isn't the 
problem. It's just that the b cards, being older, don't scan 
(or something like that, I remember sending them some 
command with maybe iwconfig and I got an error that it 
wasn't supported). I notice in the logs lots of things (like 
SCAN) that aren't working, and I don't know if it's the card 
or I've set it all up wrong.

Will go plug in a live CD (or two)

Thanks

Joe
