[SOLVED] iw reg set doesn't work

ario · 03-27-2021, 07:01 AM

Hi Folks,
I run:

Code:

iw reg get

It shows:

Code:

global
country 00: DFS-UNSET

Then I run:

Code:

iw reg set DE

Nothing happens. I tried different country codes, nothing happened.
I tried:

Code:

echo "options cfg80211 ieee80211_regdom=DE"  >  /etc/modprobe.d/cfg80211.conf

Nothing happened.
Any ideas?

It seems like the hardware driver can stop iw from setting regulation zone. As I have two wlan hardware, one built-in (raspberry pi 4) and the other USB dongle (rtl8192eu), I blacklisted the kernel module (brcmfmac) which was the driver of the built-in wlan and rebooted. With the built-in wlan disabled, now the command works on the USB dongle one:

Code:

iw reg set DE

And then:

Code:

iw reg get

shows the country code correctly.
