Hi,

Just cannot seem to get my wireless card to work :( I have enabled the new mac80211 in the kernel as I am running :-

Code:
cyborg linux # uname -a
Linux cyborg 2.6.22-gentoo-r4 #4 SMP Mon Aug 20 09:56:12 GMT 2007 i686 Intel(R) Core(TM)2 Duo CPU T7500 @ 2.20GHz GenuineIntel GNU/Linux


But when the modules loads I get the following in dmesg and no device is created :-

Code:
iwl4965: Intel(R) Wireless WiFi Link 4965AGN driver for Linux, 1.0.0-1d
iwl4965: Copyright(c) 2003-2007 Intel Corporation

Any ideas ?

I have the same problem on my Asus G1S

The problem was that the driver iwl4965 does not load kernel modules which it needs.

Try
rmmod iwl4965
modprobe blkcipher aes arc4 ecb cryptomgr crypto_algapi iwl4965

This work for me. Final solution was to add blkcipher aes arc4 ecb cryptomgr crypto_algapi iwl4965 at /etc/modules.autoload.d/kernel-2.6 and now it works.

Hope this will help

Regards

Awesome that did it :) I did load a few crypto modules but one of them was the magic one :D Do you know how to stop UDEV from loading iwl4965 as it is being loaded before modules.autoload.d kicks in ? I know it can be hashed from the persistent udev net rules, but was unsure if there is a proper method of doing this ?

Code:

# nano -w /etc/modprobe.d/blacklist
blacklist iwl4965


This command will block iwl4965 from being started by udev :)

Hm-m. I followed the described procedure on T61 and it seems to be working with WPA only with wpa_supplicant - which means that all the listed modules are irrelevant.

Can you really make iwl4965 and the in-kernel encryption work without wpa_supplicant?

Would it be too much to ask to post:

Code:
ps -ef | grep wpa

Code:
iwconfig wlan0

Code:
iwlist wlan0 scan

and /etc/conf.d/wireless?

Thank you!

For the record, I use only a WEP key, so I can't help you with the /etc/conf.d/wireless
