HI all,

i recently installed slitaz on an 2gb usb key and it is all working pretty well on my acer aspire laptop except for the built in wlan.
in mint 12 it works using iwlagn driver. slitaz also seems to have this module loaded, but the wlan hardware is just not recognized.
everything looks like my wlan card is deactivated (the little wlan indicator lamp is not flashing). in windows and in mint12 i can activate my wlan using "Fn + F3" but this doesn't work in slitaz. and ifconfig always says there is no wlan0 if i try things like "ifconfig wlan0 up".
So any suggestions for what i should do to make wlan work?

Hi, I am having the same problem with my E1228 Netbook (Medion Acoya MD98720).
The wifi interface is the Intel Centrino N 130. On Intel's website I found that drivers are implemented in the kernel 2.6.37. I run Slitaz 4.0 so that should be OK. The scan in Tazpanel/Network/Wireless brings up no networks while there should be several. So I'm too interested in answers to this problem.
Greetings, jonas

Install intel wifi firmware:
firmware-iwlwifi-1000-20110227
firmware-iwlwifi-3945-20110227
firmware-iwlwifi-4965-20110227
firmware-iwlwifi-5000-20110227
firmware-iwlwifi-5150-20110227
firmware-iwlwifi-6000-20110227
firmware-iwlwifi-6050-20110227

This will install them all,If the computer is connected with ethernet to internet.
Open terminal,su ,Password:root
tazpkg recharge
tazpkg -gi get-wifi-firmware

If the computer has no internet with ethernet you have to download the firmware on another internet connected computer from http://mirror.slitaz.org/packages/4.0/ copy to flash drive,copy to slitaz computer.
Open terminal,su, Password: root
tazpkg install <complete firmware name.tazpkg>

After firmware is installed:
Unload then load the wireless kernel module for intel wireless card after you install the firmware.
modprobe -r iwlagn ; modprobe iwlagn
Look at /var/log/messages to verify the firmware was loaded without errors.
Restart networking:
/etc/init.d/network.sh stop
/etc/init.d/network.sh start

Establish connection:
Applications/System Tools/Wifi configuration

If you need more help:
Post complete line of information about your wireless network adapter:
lspci -nn
and any errors in /var/log/messages

thanks to mojo i will try that later when i am at home. but as i have Intel Centrino Advanced-N 6205 wifi module i would, according to this site http://intellinuxwireless.org/?n=downloads , need iwlwifi 6005 which is not in the package list of slitaz. but i will try installing all of them maybe it will work with those too. edit: okay i tried instaling 6000 and 6050 now both didn't work. after modprobe there were messages from iwlagn in /var/log/messages saying it is looking for iwlwifi-6000g2a-ucode. so i downloaded the appropriate ucode from above link and placed it into /lib/firmware. after modprobe the correct firmware seems to be loaded but i have errors saying bind failed: adress already in use. i have appended the complete /var/log/messages

6005 Images – for Intel Centrino Advanced-N 6205
http://intellinuxwireless.org/iwlwifi/downloads/iwlwifi-6000g2a-ucode-17.168.5.3.tgz
You can either download/extract to /lib/firmware
or
tazpkg install firmware-iwlwifi-6000-20110227.tazpkg
Which has an older version of same firmware:
/lib/firmware/iwlwifi-6000-4.ucode
/lib/firmware/iwlwifi-6000g2a-5.ucode
/lib/firmware/iwlwifi-6000g2b-5.ucode

Edit:
Open terminal, su Password: root
wget http://intellinuxwireless.org/iwlwifi/downloads/iwlwifi-6000g2a-ucode-17.168.5.3.tgz
tar xvf iwlwifi-6000g2a-ucode-17.168.5.3.tgz
cp iwlwifi-6000g2a-ucode-17.168.5.3/iwlwifi-6000g2a-5.ucode /lib/firmware

These harmless messages are normal for SliTaz-4.0 :
Apr 28 04:01:41 (none) user.notice error binding udev control socket
Apr 28 04:01:41 (none) daemon.err udevd[4025]: error binding udev control socket
Apr 28 04:01:55 (none) daemon.err udevd[4030]: bind failed: Address already in use

Your wireless should still work.

strange.. i tried doing the procedure again from the beginning and now restarting network doesn't say :wlan0 device not found it says : shutting down wifi card. therefore my wifi card is recognized, ifconfig -a lists it too, but ifconfig wlan0 up prints an error saying not possible due to RF-kill. and during all the process the wifi indicator lamp is dark^^

See Edit in my previous post:
You have to extract the intel firmware from the tarball.
Placing the tarball in /lib/firmware won't work.
If you still can't connect I can't help without this info:
Post complete line of information about your wireless network adapter:
lspci -nn
and any errors related to the wireless firmware loading in /var/log/messages

i have never put the tarball to /lib/firmware i always extracted the .ucode file and copied it to the right location as said it seems as if the card is recognized after placing the firmware and reloading iwlagn, but it is not activated, or gets deactivated by network.sh restart perhaps? here is lspci -nn line related to wifi: 03:00.0 Network controller [0280]: Intel Corporation Centrino Advanced-N 6205 [8086:0082] (rev 34) and as this already in use errors are not related to this i cannot find any errors related to wifi firware in /var/log/messages. and after reboot the firmware is removed from /lib/firmware is this normal? edit: i finally got it working.after installing the firmware and modprobe my driver, i had to change the line Wifi="no" to WIFI="yes" in network.conf. then run /etc/init.d/network.sh restart and now all is working fine. also i found out about tazusb writefs so it is now saved across reboot....sorry for not reading this in the manual before posting

Thanks for helping me so far, but I still had no wifi connection.

In the messages I found:
/var/log/messages:
...
iwlagn 0000:02:00.0: request for firmware file 'iwlwifi-6000g2b-5.ucode' failed.
...

On Intel's site I found that I do need 'iwlwifi-6000g2b-6.ucode'
Installing this did not work

With a search on 'iwlwifi-6000g2b-5.ucode' I found:
http://www.intellinuxwireless.org/iwlwifi/downloads/iwlwifi-6000g2b-ucode-17.168.5.2.tgz
This package contains de desired .ucode file
Installed it and the wireless is working fine

So, indeed: "solved". Thanks for helping me on the road!
