WPA-PSK with wpa_supplicant and ipw3945

Neuro · 2006-08-25 08:01:04

Hi, I've just bought a notebook with the ipw3945 wifi nic and I can't associate with my WPA-PSK home network. The AP is running Slackware/hostapd 0.5.4/madwifi 0.9.2. I don't have any problems associating using Windows XP.
hostapd.conf:

interface=ath0
driver=madwifi
logger_syslog=-1
logger_syslog_level=2
logger_stdout=--1
logger_stdout_level=2
debug=0
ctrl_interface_group=0
macaddr_acl=0
deny_mac_file=/etc/hostapd.deny
auth_algs=3
eapol_key_index_workaround=0
eap_server=0
dump_file=/tmp/hostapd.dump
ssid=Continuity
wpa=3
wpa_passphrase=<some_wpa_string_key>
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP TKIP

I installed Arch (current) on the new laptop: kernel 2.6.17.11/ipw3945 1.0.12/ipw3945d 1.7.22/wpa_supplicant 0.48-3. Everything seemd to go exactly as planned, I started ipw3945d and the module and firmware were loaded. I could see the thing in iwconfig, and no errors were reported in dmesg. I could easily scan for networks etc: usual stuff.

So I did exactly what http://wiki.archlinux.org/index.php/Wpa_supplicant told me to:

iwconfig eth1 mode managed essid Continuity channel 6
ifconfig eth1 up

Then I edited wpa_supplicant.conf:

ctrl_interface=/var/run/wpa_supplicant
ap_scan=1
network={
        ssid="Continuity"
        proto=WPA
        key_mgmt=WPA-PSK
        pairwise=CCMP TKIP
        group=CCMP TKIP WEP104 WEP40
        psk="<some_wpa_string_key>
}

and run:

wpa_supplicant -Dwext -i eth1 -c /etc/wpa_supplicant.conf -d

And then... nothing worked.

I just don't know what to do. I've googled for the last hour for any clues. I tried different wpa_suplicant.conf options, i tried different -D drivers (wext and ipw) - nothing.

Anyone could help?

Nevermind. Updating wpa_supplicant to 0.5.2 and ipw3945 to 1.1.0 seems to have solved the problem.
