No luck with WPA and WPA_SUPPLICANT

mellin · 04-27-2006, 02:49 AM

I have Mandriva 2006 free installed to IBM Thinkpad T41. This laptop comes pre-installed with PRO/Wireless LAN 2100 3B Mini PCI. When initially installed, 2.6.12-12mdk-i686-up-4GB kernel supports this card with ipw2100 module.

So, let OS do all the magic and ipw2100 gets loaded, interface configured as eth1 and open networks work like charm! But, in comes the WPA and things start to go awry

I have tried with the internal Wlan card and with another one, Linksys WPC54G that gets connected to PC-CARD slot. When working with the Linksys card, i use Ndiswrapper with Windows drivers. It gets configured as wlan0 and i can scan networks through it with the iwlist utility, too.

/etc/wpa_supplicant.conf

Code:

ctrl_interface=/var/run/wpa_supplicant  # for wpa_cli support
eapol_version=1

network={
  ssid="mmwlan"
  psk="secret"
  key_mgmt=WPA-PSK
  pairwise= TKIP CCMP
  group=TKIP CCMP
  priority=2
  proto=WPA
}

Ipw2100 firmware was downloaded from the project page

Code:

[root@mandriva ~]# ll /lib/hotplug/firmware/
total 212
-rw-r--r--  1 root root 209190 Apr 25 20:03 ipw2100-1.3.fw

I load wpa_supplicant like this if using ipw2100

Code:

wpa_supplicant -i eth1 -c /etc/wpa_supplicant.conf -D ipw -d

When excuted, wpa_supplicant prints this in continues loop:

Code:

[root@mandriva ~]# wpa_supplicant -i eth1 -D ipw -c /etc/wpa_supplicant.conf -d

I doesn't matter whether i use WPC54G or internal Intel, they get, to my eye, identical output from wpa_supplicant. So it clearly has issues to deal, but i don't know where to start looking for

My router is Linksys WRT54G. WPA personal enabled, TKIP as algorithm. No MAC filter, SSID broadcast enabled.

Did you use wpa_supplicant in package form? Or did you compile it yourself?

It is a bit of a fussy program because it depends upon the rest of your environment, but that's nothing a custom compile won't fix.

I used wpa_supplicant in package form. It didn't compile for some reason on my system, so i had to use the pre-installed one.

Code:

[mellin@mandriva ~]$ rpm -q -a | grep wpa_supplicant
wpa_supplicant-0.4.4-1mdk

Nobody has any idea, what those below might mean?

Code:
