Profiler don't broadcast SSID on 5 GHz

[MaciejStawiar]

I have an issue with Profiler on WLANPi Pro.
On 2,4 GHz it works fine, but on 5 GHz it starts, but don't broadcast Profiler SSID.
Info from CLI:

wlanpi@wlanpi-095:~ $ sudo profiler
[sudo] password for wlanpi:
2023-02-19 11:26:00,238 [WARNING] interface: No IR found in iw channel information for 36 (5180) which means injection will not function!

Starting a fake AP using wlan0mon on channel 36 (5180)

Getting started:

 - Associate your Wi-Fi client to *our* SSID: Profiler 095
 - Enter any random password to connect
 - Authentication will fail, which is OK
 - We should receive an association request to 84:14:4d:a7:84:4c
 - Results are then saved locally and printed on the shell

I noticed that [WARNING] is the difference between 2,4 and 5 Ghz mode and found that "no IR" parameter is similar to scanning on DFS channels - only passive mode, so probably Profiler will not broadcast anything.

iw list confirms that there is no IR parameter in whole 5 GHz!:

any ideas how to fix that? Changing RF Domain between PL, CZ and DE have the same result.

Intel AX210 inside the Pro uses Location Aware Regulatory (LAR). It doesn’t respect the reg domain we configure, but it instead sets its reg domain automatically. It first needs to complete a scan, needs to hear a beacon from an existing AP and based on the country code in that beacon, it sets the reg domain.

If you manually force the AX210 to scan and then start Profiler, that should unlock the 5 GHz channels and remove the “No IR” flag (the flag tells the adapter not to transmit).

This should do the scan:
iw wlan0 scan

Hi Jiri,
This didn't help. Scan works and get data from neighbor WiFi:

Country: PL Environment: Indoor/Outdoor
Channels [36 - 36] @ 23 dBm
Channels [40 - 40] @ 23 dBm
Channels [44 - 44] @ 23 dBm
Channels [48 - 48] @ 23 dBm
Channels [52 - 52] @ 23 dBm
Channels [56 - 56] @ 23 dBm
Channels [60 - 60] @ 23 dBm
Channels [64 - 64] @ 23 dBm

but this didn't change profiler and iw list output.
