WPA on an Atmel based NIC??? [was: mad at wpa_supplicant]

Message

Can anybody guide me on configuring wpa_supplicant? I have spent many hours on this, have read through many posts and cannot see what am I doing wrong. wpa_supplicant continues to find no accesspoints.

My NIC is "Intel Corporation PRO/Wireless LAN 2100". I am trying to get wpa_supplicant to connect to unencrypted network first, just to make things simpler. I have now opened my router (D-Link DI-514) completely (no encryption). I am running wpa_supplicant in the following way:

Code: Select all

 wpa_supplicant -ieth1 -c/etc/wpa_supplicant.conf -d -Dipw

where /etc/wpa_supplicant.conf contains

Code: Select all

network={
        ssid="my-essid-in-double-quotes"
        key_mgmt=NONE
}

I always get no access points:

Code: Select all

....

and so on... Chagning the driver to -Dwext changes some of the messages but the net effect is the same. No APs are found. I am desperate now. Needless to say the same networks connects with no problemws whatsoever using wireless tools.

My mileage is similar if I activate WPA-PSK on the router and configure the machine accordingly. I am seeing on two machines with different hardware, so I must be doing something wrong. What may I be missing? A cry for help...

You should be using -Dwext for the ipw2x00 stuff. Post the errors using -Dwext.

When you say you "can't find any APs", do you see your AP with `iwlist eth1 scan` ? Even with wpa_supplicant not started, you should at least see your AP.

This is a good point. Normally I can see the APs around, but now I could not. It seems that there might be some instability in the kernel module. I have reloaded the ipw2100 and now iwlist can see my access point ... and ... wpa_supplicant works! Thanks a lot!

I kill wpa_supplicant and try to run again and nothing works as before (no APs in iwlist and wpa_supplicant). Reloading the module helps again. Is there any known instability with this in-kernel driver?

(I am using the wext driver with wpa_supplicant, as you suggested).

Ok. Perhaps it is not fully smooth, but I can at least connect from my ipw2100 nic. My other machine has a PCMCIA Atmel based nic, and I still have no success with it.

Hallo?... is there any body out there running WPA with an Atmel based NIC? Give me at least a bit of hope ...

EDIT: just a remark that I did not have time to work on that problem recently, but I am still interested in solving it. I do not want it to disappear from egosearch thread list.
