Madwifi driver setup for WPA-PSK wireless encryption

Hi Group,

I thought I was so close to having a complete setup, but then a problem.

Here's the background:

Using archlinux with stock kernel 2.6.22 on IBM T21 or T23 Thinkpad.
Using an pcmcia SMC SMCWCBT-G network adapter.
I am using the latest 0.9.4 madwifi source tar.gz
The proper atheros madwifi drivers are installed and the ath0 device is active and functional.
Reading along in the madwifi docs, I found that I also had to install "Linux WPA Supplicant" in order to connect to a WPA secured router or access point.
I made the .config file as suggested in the Supplicant README and I set the defconfig file to work accept madwifi.

But when I try  ~$/opt/wpa_supplicant-0.5.10/make   I get the following errors and cannot figure what to do ---

Why the freebsd errors??
Any help or guidance greatly appreciated

Re: Madwifi driver setup for WPA-PSK wireless encryption

Your kernel is very old, pacman -Syu to update everything.

Then you can do:
pacman -S madwifi wpa_supplicant
to install those two. You might find netcfg easier to use, have a look at the wiki page "Network Profiles"

Re: Madwifi driver setup for WPA-PSK wireless encryption

Thanks for the reply, Iphitus.
I removed the source madwifi and wpa_supplicant installation and used pacman after the major update.

I setup the wireless to use netcfg2 command, but the connection still fails --

err, ath0: timed out
                    - DHCP IP lease attempt failed                                           [FAIL]

I'm wondering if maybe I've overlooked something basic -- my access point is setup to use wpa2.  does wpa_supplicant not work with wpa2?
I'll do some googling and see if I can find anything.

I appreciate your time and help.

Re: Madwifi driver setup for WPA-PSK wireless encryption

okay, if i'm understanding correctly, wpa_supplicant does work to configure connections by way of wpa2.

now, I'm still not sure about what I need to provide in /etc/wpa_supplicant.conf since i thought setting up a netcfg configuration file would control the process of handling the wpa2 connection...........need more RTFM.

will try again tomorrow.

Re: Madwifi driver setup for WPA-PSK wireless encryption

I don't know if you already looked at that page http://www.thinkwiki.org/wiki/Wpa_supplicant but perhaps you'll find some hints on what settings to use.
I think the most important thing is to use the correct driver for wpa_supplicant, in the case of the "old" madwifi drivers -Dmadwifi is required instead of the default -Dwext for the commandline option of wpa_supplicant.

Re: Madwifi driver setup for WPA-PSK wireless encryption

read the Arch wiki regarding netcfg "Network Profiles". There are responses to your error message user1100100.

If the instructions provided for you error message fail to rectify the problem, then try the version of netcfg in [testing]. Details for that are on "Network Profiles development"

Re: Madwifi driver setup for WPA-PSK wireless encryption

Thanks for the followup help Iphitus and WhiteMagic.
I will give this a run-through later today.
