HOWTO: ipw2200 + wpa

[dejitarob]

there is linux-kernel-headers, linux-headers-2.6.10-5 and linux-headers-2.6.10.5-686 (or 386, k7, etc depending on what kernel you are using)

Thanks for the HOWTO luca_linux. However I'm having the same problem as meesmany. I have an IBM ThinkPad T41 with an ipw2100. I downloaded the latest firmware and source for ipw2100. Copied the firmware to the right folder, compiled the drivers and copied them to the right folder. Installed and configured wpasupplicant.conf just like you mentioned with my own essid and psk ofcourse but I can't get my card to associate with my LinkSys WAG54G ap. Here is the output from some commands:

firas@ibm-t41:~$ dmesg | grep ipw2100

I even tried setting my essid manually using iwconfig eth1 essid my-essid to no avail. I disabled WPA on my AP and was able to connect just fine using iwconfig.

Can anyone shed any light on this problem ? I'm really getting desperate here, I've spent days on this with no luck.

And a little off topic here. How can I disable IPv6 on my laptop (the sit0 interface) permanently ?

I have the same problem as firas, don't get any error message but wpa doesn't wan't to work. Without encryption i get a connectin to my router.

I updated to the latest driver and firmware. No improvement.

What looks strange to me is that sudo wpa_cli status returns the following

Selected interface 'eth1'
bssid=00:00:00:00:00:00
pairwise_cipher=UNKNOWN
group_cipher=UNKNOWN
key_mgmt=UNKNOWN
wpa_state=SCANNING
Supplicant PAE state=DISCONNECTED

suppPortStatus=Unauthorized
EAP state=DISABLED

Why does it complain key_mgmt=UNKNOWN. It is set to key_mgmt=WPA-PSK in /etc/wpa_supplicant.conf and manually starting wpa returns: key_mgmt: 0x2 analog to firas post.

I am now trying to build a vanilla kernel from kernel.org and install ipw2100 again. At the moment i am getting mad. I checked every config i know several times. No errors in the log and i know the wpz_supplicant.conf hast to work, as it did in gentoo, before i switched to ubuntu. My stomache realy hurts cause of waisting time with this @#%^&*( network encryption.

I additionaly found this Bugreport, but without a solution:

https://bugzilla.ubuntu.com/show_bug.cgi?id=9970


Hope firas or anyoneelse solved the problem with 2100 and can give me a hint.

Ok, i followed the HowTo
all seens to work:

but i cannot connect to the internet (timeout) with firefox or ping for example...
PLEASE, need help

edit: it seems, that the WLAN DOES something, i can see the MAC-address in the AP-menu, but no IP!
how i can configure my eth1 for DHCP??
sould i do something with /etc/network/interfaces?

before last apt-get update i had no problems with this configuration

[dejitarob]

sudo ifdown eth1 then sudo ifup eth1 will get a new ip address. Look at the latter part of the guide for info on how to start wpa_supplicant on bootup. If you do this the network daemon should automatically get a new IP on bootup.

[motion_blur]

no, does not work,
now the driver is broken or something...
at startup i get errors like this:

ipw2200: failed to send ASSOCIATE command
ipw2200: failed to send SSID command
ipw2200: ipw_send_system_config failed
ipw2200: failed to send SSID command

ipw2200: no space for Tx

[MrSandman]

if there a definative tutorial on how to do this? i have tried and tried and i keep getting the make error, so do i need the header package also?

i am pretty much a newbie.

This is a pretty much definative but it does assume you have a bit of experience with compiling which is easy once you do it and learn to interpret the error messages. So what is the error message you are getting? Where are you getting stuck at? If you are more specific, we can help.

Make sure you are disabling your wireless card in the BIOS or through a button the keyboard. If not, try reinstalling being sure to remove the old drivers.

Yes, you need the kernel headers or the kernel source.

Hi ive done everything in your howto, but when i start up my computer, i get this message from dmesg, with the command dmesg | grep ipw..

ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.0.4

i dunno what this means, but it seems that i cannot get the wireless interface to function properly, im sending screens of iwconfig eth1 and /etc/network/interfaces too

the only thing i get when i do try to take the interface up is that it dhcp.. request and different intervals, you know
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 8
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 10

my router stands on this settings

SSID

Encryption
AES_CCMP
its a D-link di-624

hope this information is enough

thanks for the howto, with this i at least got a MAC-address ;D

thanks for the tip
