   My initial message seems to irritate get-feeds.php (because of imbedded control characters), so that the slitaz home page shows a lot of error messages in the activity window.
   I am sorry for that.

   Hi Hans,

   I removed all the control characters from your post and added "code backticks".

   Have a nice day!

   you have to change network.conf and

   /etc/init.d/network.sh restart

   After setting WIFI="yes" in /etc/network.conf
   # /etc/init.d/network.sh restart
   results in:

   Loading network settings from /etc/network.conf
   Stopping all interfaces
   ifconfig: SIOCGIFFLAGS: Kein passendes Gerät gefunden
   Killing all daemons
   killall: udhcpc: no process killed
   wlan0 No such device

   wlan0 is not a Wi-Fi interface, changing it.
   Configuring Wi-Fi interface ... lo no wireless extensions.

   dummy0 no wireless extensions.

   eth2 no wireless extensions.

   eth1 no wireless extensions.

   tunl0 no wireless extensions.

   [ Fertig ]
   Change network settings in /etc/wpa/wpa.conf
   iwconfig: unknown command "any"
   Configuring static IP on : ###.###.###.###...
   ifconfig: SIOCSIFNETMASK: Kein passendes Gerät gefunden
   route: SIOCADDRT: Das Netzwerk ist nicht erreichbar
   Connecting to any... [ Fehlgeschlagen ]

   network.sh looks for wlan0 in /sys/class/net, but there is no such device:
   $ ls /sys/class/net
   dummy0 eth1 eth2 lo tunl0

   $ find /sys/devices/pci0000\:00/ -name "net"
   shows only:

   /sys/devices/pci0000:00/0000:00:1c.1/0000:02:00.0/net
   /sys/devices/pci0000:00/0000:00:1c.2/0000:03:00.0/net

   and these are the ethernet adapters only:
   # ls /sys/devices/pci0000:00/0000:00:1c.1/0000:02:00.0/net
   eth1
   # ls /sys/devices/pci0000:00/0000:00:1c.2/0000:03:00.0/net
   eth2

   I think something goes wrong with
   # modprobe iwlwifi
   that loads the drivers but does not create a device tree for wlan0 in /sys/devices

   On another computer with another WLAN adapter (Ralink), after modprobe a new branch in the devices tree is created for wlan0.

   iwlwifi-3160 requires iwlmvm firmware loading is not enabled in the 64-bit kernel.

   Thank you Richard,
   your resolution is a full success:
   The module iwlwifi is now loaded automagically after booting SliTaz Rolling 64bit flavor and wlan0 shows up and can be configured.
