   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.

   The wifi adapter uses iwlwifi kernel driver and iwlwifi-2000-6.ucode must be install before iwlwifi is modprobed.
   wget http://cook.slitaz.org/packages/firmware-iwlwifi-2000-20130610.tazpkg
tazpkg install firmware-iwlwifi-2000-20130610.tazpkg
modprobe -r iwlwifi && modprobe iwlwifi

   If you use /home/boot/packages auto install on boot:
   cp firmware-iwlwifi-2000-20130610.tazpkg /home/boot/packages
   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
   iwlwifi 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17

   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

   udev is loading iwlwifi before the firmware is installed.
   Add
   modprobe -r iwlwifi && modprobe iwlwifi
   to
   /etc/init.d/local.sh

   Hello Mojo,

   Thank you again it works.

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

   Jules.
