Jessie: cfg80211: Calling CRDA to update world regulatory domain

Question

I have this message repeated multiple times on Jessie.

cfg80211: Calling CRDA to update world regulatory domain
...
cfg80211: Exceeded CRDA call max attempts. Not calling CRDA

Everything looks like is working fine, however I'm not totally sure.

Any advise how to fix this?

Answer 1

Looks like the CRDA package was missing from Jessie.
To fix this issue just install the CRDA package

apt-get install crda iw wireless-regdb

then reboot and the message will change as follows:

This partially worked for me. The CRDA still wasn't set on reboot:

[ 7.968805] cfg80211: Calling CRDA to update world regulatory domain [ 8.259604] cfg80211: World regulatory domain updated: [ 8.267114] cfg80211: DFS Master region: unset [ 8.271820] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp), (dfs_cac_time) [ 8.286116] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (N/A, 2000 mBm), (N/A) [ 8.296448] cfg80211: (2457000 KHz - 2482000 KHz @ 40000 KHz), (N/A, 2000 mBm), (N/A) [ 8.306754] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (N/A, 2000 mBm), (N/A) [ 8.317328] cfg80211: (5170000 KHz - 5250000 KHz @ 80000 KHz, 160000 KHz AUTO), (N/A, 2000 mBm), (N/A) [ 8.329702] cfg80211: (5250000 KHz - 5330000 KHz @ 80000 KHz, 160000 KHz AUTO), (N/A, 2000 mBm), (0 s) [ 8.342143] cfg80211: (5490000 KHz - 5730000 KHz @ 160000 KHz), (N/A, 2000 mBm), (0 s) [ 8.352515] cfg80211: (5735000 KHz - 5835000 KHz @ 80000 KHz), (N/A, 2000 mBm), (N/A) [ 8.362778] cfg80211: (57240000 KHz - 63720000 KHz @ 2160000 KHz), (N/A, 0 mBm), (N/A) .

Adding:

country=CA

to /etc/wpa_supplicant/wpa_supplicant.conf didn't work.

Adding:

REGDOMAIN=CA

to /etc/defaults/crda didn't work. Then I read to also add:

COUNTRY=CA

to /etc/environment and that also didn't work.

Only way I could do it was to manually enter:

sudo iw reg set CA

After reboot. I made persistent by adding this to /etc/rc.local but I still get an unset region on boot and then it gets set when rc.local runs. To me this seems an absolute mess and needs fixing!
