How to use crda?

GogglesGuy · 2009-01-06 15:19:10

Optional dependencies for kernel26
    crda: to set the correct wireless channels of your country

pacman -S crda
resolving dependencies...
looking for inter-conflicts...

Targets (2): iw-0.9.7-1  crda-0.9.5-1

Besides installing crda, anything else that needs to be done (config files etc) ? I couldn't find much docs on crda here.

Ok. so to summarize either:

1) Do nothing, don't install crda;

Some default channels will be enabled 
(like 1-11) and the old hardcoded US, JP and EU domains (via the 
cfg80211_regdom module parameter)

2) Install crda, uncomment the correct wireless regional domain in /etc/conf.d/wireless-regdom and add "wireless-regdom" to the DAEMONS

3) Install crda, but use wpa_supplicant to set the domain (and possibly a future networkmanager to do this)

I just did 2) and it works, in fact it was working without installing crda but I see why we need to set the region.

At system boot, I get the following message

:: Setting wireless regulatory domain: DE                                [BUSY]
nl80211 not found.                                                                         [FAIL]

I did step 2) My wireless network still works without a successful start of this daemon. Google gives me some search results, but I don't exactly know, what to do to solve this. I have an ipw2200.

Packages are out of testing. I get the same "error". Is it really an error? Whats wrong??
I have nl80211 compiled in:
$ zgrep -i nl80211 /proc/config.gz
CONFIG_NL80211=y

i'm getting the same error. i know i already had it working once without this error msg...

diaz, afaik this only enables wireless channel 13 where applicable (correct me if i'm wrong)

Problem is gone for me with latest crda upgrade of today.

bash-3.2# /etc/rc.d/wireless-regdom start
:: Setting wireless regulatory domain: DE                                [DONE]

Because if you live in a country where channel 12 and 13 can be used and some AP is using it you need to set your country to the correct one (or one that "allows" you to use those channels), otherwise its just like they aren't there, just did a quick test with my router and without crda channel 13 doesn't show up in scans, with crda and country set to PT (my country code) channel 13 pops up in the scans.

Diaz · 2009-01-20 22:11:23

ah good to know. so in my country - portugal - i need to enable it...

R00KIE · 2009-01-21 12:28:33

I would say yes, just in case you need to use channel 12 or 13.
My guess is (and I can't be sure) that most equipment is configured to use up to channel 11 to keep compatibility problems to a minimum due to stuff like software not configured properly.

Diaz · 2009-01-24 03:37:54

there's a 4th way to do it.

4) intall cdra and put someting like:

sudo vi /etc/modprobe.d/my_options
options cfg80211 ieee80211_regdom=PT
:wq

no need to change file in conf.d no need to load another deamon to change it.

Nice
I just change the proper config file and then load the daemon in the background, it's more in line with how almost everything works so its easier to remember in the future (for me at least).
(Oh and I guess just a few people will understand cumps at the end , regards will be understood by everyone )

It is also needed to enable 802.11n wireless in some countries
