Odd wireless problem with Slackware-current on Latitude 110L


Hi,

I installed Slackware-current on a Dell Latitude 110L laptop, and so far everything is working fine except for an odd wireless problem: when connecting to a wireless network with WPA-PSK, the connection lasts only a few seconds before dying.
The laptop has a built-in Intel 2200 wireless chip driven by the ipw2200 module.

I generally use Wicd to manage my wireless network connections, so I thought that perhaps it might be a problem with this program, however even if I manually configure and launch wpa_supplicant + dhcpcd, the connection still falls after a few seconds.

Here is a snippet of my /var/log/messages during the time I insert the kernel module, bring up the interface, authenticate with wpa_supplicant and then use dhcpcd to get an IP address:

Code:

In the lines I highlighted, the dhcpcd daemon looks like it's committing suicide or something
Note that if I don't call dhcpcd, then the interface stays up and wpa_supplicant maintains the authentication with the router just fine.
Its only after I call dhcpcd that I lose my connection.

Next I tried a wireless USB dongle, and I managed to connect and maintain the connection without problems, but the log still shows dhcpcd dying once and then reconnecting:

Code:

So with the dongle, the daemon restarts and reconnects, but this doesn't happen with the on-board wireless card for some reason.
Also, I went to my college campus which has an Eduroam setup (WPA-EAP + TTLS + MSCHAPv2), and there I managed to maintain a stable connection.

Has anyone ever had a similar problem? I really can't fathom this one out.

Check 2 things
Dec 5 18:25:40 sirius kernel: ipw2200 0000:02:03.0: firmware: requesting ipw2200-bss.fw
Have you the latest firmware? All modern drivers seem to need it.
Also, it is possible to put your key into wpa_supplicant.conf and think that's all you need. Not so Run this command if you haven't already
wpa_passphrase my_essid my_key and that will return

bash-3.1$ wpa_passphrase my_essid my_key_short
network={
ssid="my_essid"
#psk="my_key_short"
psk=3de1dca3d740a5c9cdb6640a44040f9353944a9a695190e3f3d25bfe0cb21fef
}

Put the bit between brackets in wpa_supplicant.conf. It's the long number the thing needs
