   Hello everybody

   I am new here,so let me say at first, THANK YOU, to all who made
   this wonderful OS possible.

   I'm using Slitaz 4 stable, and with reading almost all of the topics
   in this forum,I was able to configure everything to my liking.
   but one problem is still remaining, and as I am only a user and not a coder
   I need some help to get it fixed.
   now what is the prob ....in short
   here in Germany you can use the wifi-channels 1-13,but all the usb-wifi
   you can buy, is interally branded to the Regdomain CN or US, which only allows
   channel 1-11.
   Unfortunatly the AP to which I have to connect to,often switch to channel 13,
   and then I am off, and if so I have to use another OS. :-(
   After some googeling I find out what I need, It's called CRDA,
   and a regulatory.bin, to get all channels back.
   Till now I could not find something like that for my slitaz
   So Please is there someone able to help me out ?

   Thanks for reading and regards from Berlin/Germany.

   Hi sixofeight,

   Actually, SliTaz have no CRDA and regulatory.bin.
   I found web site with info related CRDA. Maybe it helps you: http://wireless.kernel.org/en/developers/Regulatory/CRDA#Using_iw_to_change_regulatory_domains
   Install iw package as root:
   tazpkg -gi iw
   Try command to read current state:
   iw reg get
   Try commant to set regulatory domain for Deutschland:
   iw reg set DE
   ________
   I tried these commands for my country, Ukraine, but they not works. Maybe we need some descriptive files for countries? Need to deep to documentation from that site:

   • http://wireless.kernel.org/en/developers/Regulatory
   • http://wireless.kernel.org/en/developers/Regulatory/Database?alpha2=DE

   Hi Aleksej

   I've tried to change the Regdomain-setting with iw before, it doesn't work because it comes to late.the Regdomain settings can only be changed at the moment when your usb-wifi
   is detected and configured.
   Thanks for the links,I have read them all,this is why I know what is needed.but I don't know anything about coding or compiling packages......It seems I am lost....

   ----------------------------------------------------------------------------------------
   Just to be a little more precise
   At the moment you connect your usb-wifi:
   cfg80211: Calling CRDA to update world regulatory domain
   and if there is no,it will use the branded one.
   thats why iw always comes to late.

   At the moment you connect your usb-wifi:
   cfg80211: Calling CRDA to update world regulatory domain
   and if there is no,it will use the branded one.

   I have a lot of these messages in the console (see my topic wlan garbage in console). So, does it mean that I'm a lucky? Can I configure my wlan "on the fly"?

   I prepared package with latest regulatory.bin (see in the attachment), install it.
   I tried iw command again, but no luck. Note, I'm like a monkey: I do but can't understand what I do :)
   Let's wait mojo, he is our wireless guru.

   @Aleksej

   what's In your other topic looks really strange, as there are many
   authenticate, deauthenticated and associate Lines.It looks like
   a Loop trying to establish a stable connection with 54:04:a6:8b:f7:f8

   Normally it should look like that:

   cfg80211: Calling CRDA to update world regulatory domain
   [ 7487.580544] cfg80211: World regulatory domain updated:
   [ 7487.580557] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp)
   [ 7487.580565] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
   [ 7487.580571] cfg80211: (2457000 KHz - 2482000 KHz @ 20000 KHz), (300 mBi, 2000 mBm)
   [ 7487.580577] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm)
   [ 7487.580583] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
   [ 7487.580589] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
   [ 7488.662364] wlan0: authenticate with 84:c9:b2:d5:95:18
   [ 7488.759719] wlan0: send auth to 84:c9:b2:d5:95:18 (try 1/3)
   [ 7488.761662] wlan0: authenticated

   (thats not the output of slitaz because I have to use channel 13 right now
   and here we have a working CRDA too.)

   thanks for the wireless regdb, I Think that is the first 1/2 ,but the CRDA-module
   is also needed,because this is the udev-helper-tool to use the wireless regdb ;-)

   EDIT:

   CRDA Authors wrote:
   CRDA acts as the udev helper for communication between the kernel and userspace
   for regulatory compliance. It relies on nl80211 for communication.
   CRDA is intended to be run only through udev communication from the kernel.

   well, I have to admit, I am a noob....I tried to solve it myself...no success

   I have tried to convert a debian(CRDA)-package..(tazpkg convert somewhat.deb)
   converting = OK...working = no

   I read some more about CRDA and wireless-regdb and how to build packages for slitaz (all Info is in English...understanding...maybe 1/2)
   I am getting a headache...giving up....for now

   I would be really grateful for any help

   regards at all

   This prob. (missing wlan-channels 12,13 ) is solved.
   I found a better usb-wifi:
   D-Link DWA-140 B3 USB
   Ralink RT5370 ID 2001:3c15 and after installing mojo's driver-packgage:

   Glad to see you managed to sort it, even if it meant buying another product. That info could be useful to someone else, so thanks for posting.
