NO-ir

Hello.

Have chip RTL8832BU.

Not sure this is issue but not don't know where ask the question :/
Command "iw reg get" give me:

root@debian:~# iw reg get

but for 5 GHz all channels is set to NO-IR

                        * 5885 MHz [177] (20.0 dBm) (no IR)

and due to cannot start hostapd:

root@debian:~# hostapd /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd.conf
wlx909164729982: interface state UNINITIALIZED->COUNTRY_UPDATE
Channel 44 (primary) not allowed for AP mode, flags: 0x403873 NO-IR
wlx909164729982: IEEE 802.11 Configured channel (44) not found from the channel list of current mode (2) IEEE 802.11a

Probably due to below config

phy#0 (self-managed)
country 00: DFS-UNSET

cannot set AP. Above can by change by 8852bu module from country "00" to other?

Hi @kzajac83

Run the following:

$ sudo sh edit-options.sh

That command will allow you to edit the correct 8852bu.conf file. The file contains a lot of docs regarding the module parameters that are available. You have to read the 8852bu.conf file. There is a module parameter called rtw_country_code. I would suggest adding rtw_country_code=PL to the options line.

With that said, I have not investigated this specific issue on this driver so I don't know if additional things would need to be done or if it will work at all. This is not the greatest driver but we are used to that from Realtek.
