CRDA Issues with hostapd

[Thiudans]

Hello everyone --

This is my first post. A little history. I have a finless PC running Centos7 as an access point. Everything works fine in the 2GHz band, but when I try too set up the 5GHz band, the radio does not start.

Here are some outputs:

Output of iw reg get

So far, so good!

However, when I run coda I see this:

Code: Select all

[root@localhost ~]# crda
COUNTRY environment variable not set.
[root@localhost ~]# 

This is stopping me from running on the 5GHz band, as every time I configure the configuration file for 5GHz the radio does not initialize.

Everything works fine on the 2GHz band.

I have searched the web, but I have found nothing -- which does not mean it isn't there....

All the parameter names in an /etc/sysconfig/network-scripts/ifcfg-$interface file are case sensitive and must be upper case. So COUNTRY is not the same as country. The parameters themselves (the bit on the right hand side of the = sign) can be any case as far as I know.

Hello Trevor,

I do not have an ifcfg for ,my wlan, do I need one? (Everything works fine on 2 GHz...) Also, I did not see the COUNTRY keyword for rfcfg anywhere.

Finally, if I try to manually set the country, I get the following:

Code: Select all

[admin@localhost ~]$ sudo iw reg set US ; COUNTRY=US /usr/sbin/crda
Failed to set regulatory domain: -28
[admin@localhost ~]$ journalctl | grep crda

A couple of things that are confusing me. I get an error what I try to set the country code, then it looks like the code is not set, but then it looks like it is set.

I did notice "global" is blank. Is that significant? Also, I am getting -28 now with coda, but before I got -7. I have no idea I that is significant, because the coda man page does not mention it.

The $COUNTRY variable does not seem to take, unless I first type COUNTRY=US. Then, if I run crda I get the generic coda error again.

Code: Select all

[root@localhost ~]# COUNTRY=US
[root@localhost ~]# echo $COUNTRY
US
[root@localhost ~]# /usr/sbin/crda
COUNTRY environment variable not set.
[root@localhost ~]# 

I also have the user rule for coda in /etc/udev/rules

Thanks for your help!

So what is the 2nd file you posted in your initial post? The one that starts with " Change wlan0 to your wireless device"

[Thiudans]

That is my hostapd.conf file.
