iwlwifi is not working

Hello,

I try to enable the wifi connection without success

I have tried this but my error seems to be different.

http://forum.slitaz.org/topic/slitaz-40-and-rc-wont-detect-active-and-fuctioning-wi-fi-connection-from-live-cd/page/2#post-34581

dmesg error is :

lib80211_crypt: unregistered algorithm 'NULL'

lib80211: common routines for IEEE802.11 drivers

lib80211_crypt: registered algorithm 'NULL'

libipw: 802.11 data/management/control stack, git-1.1.13

libipw: Copyright (C) 2004-2005 Intel Corporation <jketreno@linux.intel.com>

ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.2.2kmprq

ipw2200: Copyright(c) 2003-2006 Intel Corporation

lspci is :

03:00.0 Network controller: Intel Corporation Centrino Wireless-N 2200 (rev c4)

I have loaded ipw2200. lsmod return:

root@slitaz:~$ lsmod | grep ipw

ipw2200               106537  0

libipw                 17775  1 ipw2200

lib80211                2453  2 ipw2200,libipw

cfg80211              117342  4 ipw2200,libipw,iwlwifi,mac80211

when I launch the command iwlist wlan0 scanning

the result is : wlan0     Interface doesn't support scanning.

Maybe the error is due to lib80211_crypt: unregistered algorithm 'NULL' error.

Do you know how to fix this error ?

Thanks

Jules.

Re: iwlwifi is not working

The wifi adapter uses iwlwifi kernel driver and iwlwifi-2000-6.ucode must be install before iwlwifi is modprobed.

[c]wget http://cook.slitaz.org/packages/firmware-iwlwifi-2000-20130610.tazpkg[/c]

[c]tazpkg install firmware-iwlwifi-2000-20130610.tazpkg[/c]

[c]modprobe -r iwlwifi && modprobe iwlwifi[/c]

If you use /home/boot/packages auto install on boot:

[c]cp firmware-iwlwifi-2000-20130610.tazpkg /home/boot/packages[/c]

Reboot

Firmware should auto install on boot and iwlwifi auto load.

If adapter is not initializing verify with lsmod and check dmesg for errors relating to firmware load or rfkill.

Use lspci -nn to output pciids

I had to search your output with google to get them.

03:00.0 Network controller [0280]: Intel Corporation Centrino Wireless-N 2200 [8086:0890] (rev c4)

Grep modules.alias with your wifi adapters pciids to identify matching kernel module driver.

grep 8086.*0890 /lib/modules/3.2.53-slitaz/modules.alias

alias pci:v00008086d00000890sv*sd00004822bc*sc*i* iwlwifi

alias pci:v00008086d00000890sv*sd00004422bc*sc*i* iwlwifi

alias pci:v00008086d00000890sv*sd00004022bc*sc*i* iwlwifi

Grep your dmesg.txt for iwlwifi kernel messages.

grep iwlwifi dmesg.ipw2200.txt

Re: iwlwifi is not working

Hello,

Happy new Year !!! :-)

Thanks Mojo! it works when I load manually the iwlwifi module

modprobe -r iwlwifi && modprobe iwlwifi

but not Slitaz at boot.

/etc/modules.conf or /etc/modules-load.d/ do not exist on system.

I have tried also to modify rcS.conf (LOAD_MODULE parameter) and then moved it to /home/boot/rootfs/etc to be taken into account at boot

how to load the module at boot ?

Thanks.

Jules

Re: iwlwifi is not working

udev is loading iwlwifi before the firmware is installed.

Add

[c]modprobe -r iwlwifi && modprobe iwlwifi[/c]

to

/etc/init.d/local.sh

Re: iwlwifi is not working

Hello Mojo,

Thank you again it works.

I added "[c]/etc/init.d/network.sh restart[/c]" to the local.sh file because local.sh is called after network.sh.

Jules.
