Raspberry Pi 3 with OSMC unable to use wifi channels 11,12,13 in UK

Having built a card with OSMC for my new Pi3 I find I cannot connect to my wifi as it is using channels 11,12,and 13 - all the others have loads of interference!

I have managed to glean using iw list (I don’t really understand what that is but fond it on the net in an article about pi3’s and wifi) that channels 11,12 and 13 are disabled.

How can I enable them?

sudo apt-get install iw
And then iw reg get to check which region is set.

I don’t think anything is set?

Tried a sudo iw reg set GB and then reg get again and it says country GB. Channel 13 shows up! Thanks

However, when I reboot it goes back to no country. Can I make it permanent?

Got same issue.
Needed to install CRDA to get it work “apt-get install crda”.
Then “sudo iw reg set CZ” and it start to work

Seems that to make the country change permanent across reboots the code needs to be set in /etc/default/crda. then everything works fine

Plz give the exact commands and procedure to edit the crda file to enable channels 11,12 & 13. I did it xbian before but not sure of the procedure anymore.

Written just above

Where CZ should be replaced by the region you are living in

can i update it to jp

how to scan for available networks via ssh and enter the networking credentials for connecting to a network.

i cannot be able to set country change permanent. What should be added in crda file and how?

What are the outputs of
sudo iw reg set JP
And then
sudo iw reg get

Not set permanently…:disappointed_relieved:

I am speaking a foreign language?

Also provide output of grab-logs -J -K

Please also show the output of those two commands.
sudo iw reg set JP
sudo iw reg get

I decided to set it to IN instead. this is the output
