ipw2200 refuses to connect with wpa encryption

dive · 09-22-2008, 04:24 PM

After much googling I can't make any headway with this. If I change my router to use unsecured network I can connect with wicd easily, but using wep or wpa fails.

Running wpa_supplicant in a terminal produces:

Code:

wpa_supplicant -Dwext -ieth1 -c/etc/wpa_supplicant.conf               
Trying to associate with 00:1e:2a:00:b6:8c (SSID='DarkStar' freq=2462 MHz)
Associated with 00:1e:2a:00:b6:8c
ioctl[SIOCSIWENCODEEXT]: Invalid argument
WPA: Failed to set PTK to the driver.
ioctl[SIOCSIWENCODEEXT]: Invalid argument
WPA: Failed to set GTK to the driver.
RSN: Failed to configure GTK
Authentication with 00:1e:2a:00:b6:8c timed out.
CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys

Any ideas? I'm almost thinking of pluging in the atheros card from my other laptop, but that will be a pity since this T42 has a built in card.

Also, I followed this page http://gentoo-wiki.com/HARDWARE_ipw2200 and made sure that my kernel had the right crypto support etc

Why should that not fail?

Eh? I mean I set router with wpa psk and set laptop likewise and it will not connect.
wpa_supplicant says authentication timed out.

Please forgive me -- I misread your post.

Have a read of Configuring your network in Slackware by Alien Bob.
I really can't add anything to that excellent write up, and he is the guy
who maintains those scripts for Slackware.

It seems there are some different suggestions for configuring a network in
Slackware. However, I've always just used /etc/rc.d/rc.inet1.conf in our LAN
on 8 boxen, with customer's comps, and not touched /etc/rc.d/rc.wireless.conf
and never have problems. (I do use /etc/wpa_supplicant.conf)

I know that to use wicd you should not have anything set in those two files,
or it won't work properly.

Yes I have read Alien Bob's page. The problem seems to be the same that auth times out. Setting a timeout of 30 secs makes no difference.

Only three things that might be worth checking:

Is there not supposed to be a space after the "-c" switch"

Code:

wpa_supplicant -Dwext -ieth1 -c/etc/wpa_supplicant.conf

in your command here, i.e.:

Code:

wpa_supplicant -Dwext -ieth1 -c /etc/wpa_supplicant.conf

When you use wicd, are you entering the "passphrase" you used to create
your WPA-PSK, or are you entering the actual key?

wpa_supplicant doesn't really care about the space or not. I have tried using passphrase and key. According to that page there are some stability issues with some things to try out. Have to say though that it worked fine in win xp before I wiped the hdd.

Stupid question:

Have you configured /etc/wpa_supplicant.conf ?

You must edit 3 files:

/etc/rc.d/rc.inet1.conf

Just set WLAN_WPA[i]="wpa_supplicant", in addition to conventional link options (dhcp options, etc.)

/etc/rc.d/rc.wireless.conf

Just set the initial INFO and ESSID options, with a description and your router's ESSID.

/etc/wpa_supplicant.conf

Use default settings:

Code:

# WPA protected network, supply your own ESSID and WPAPSK here:
network={
  scan_ssid=0
  ssid="ESSID"
  proto=WPA
  key_mgmt=WPA-PSK
  pairwise=CCMP TKIP
  group=CCMP TKIP WEP104 WEP40
  psk="WPA-PSK KEY"
}

Be careful with the psk option here. If you enter your raw (not encoded) key, you must add quotes (I guess).

Also, if you use hidden ESSID, you must set scan_ssid=1 .

Thanks for replies. Yes I had set all those.It turned out that the kernel ieee80211 and ipw2200 drivers included with the kernel are missing many features, and some settings needed for encryption cannot be set in the driver.

I solved this by installing the ieee80211 and ipw2200 drivers from sourceforge.net.

Seems ok so far.
