What happened?

Hi! thanks for creating this wonderful resource.

I am using a Netgear A800 on Linux kernel 6.6 -

driver: mt7921u
version: 6.6.31+rpt-rpi-2712
firmware-version: ____010000-20240716151027

and hostapd version v2.12-devel-hostap_2_11-16-g92374d59d (compiled with the config described here.)

I haven't been able to get it to use 6GHz in AP mode. Relevant part of the hostapd config is

hw_mode=a
channel=37
chanlist=37
op_class=134
country_code=US
country3=0x49
ieee80211d=1

The error message I get is

SAE: Enabling SAE H2E on 6 GHz
wlan1: interface state UNINITIALIZED->COUNTRY_UPDATE
Frequency 6135 (primary) not allowed for AP mode, flags: 0x13803 NO-IR
Primary frequency not allowed
wlan1: IEEE 802.11 Configured channel (37) or frequency (6135) (secondary_channel=1) not found from the channel list of the current mode (2) IEEE 802.11a
wlan1: IEEE 802.11 Hardware does not support configured channel
Could not select hw_mode and channel. (-3)
wlan1: interface state COUNTRY_UPDATE->NO_IR
wlan1: AP-NO_IR

(I have tried a few different 6GHz frequencies with the same result.)

I also see in iw list that it shows "no IR" for all the 6GHz channels -

Do you know if it is possible to use this device in AP mode on 6 GHz? (If not, do you know if there is another one that does support AP mode on 6 GHz?)

Thanks!

P.S. I'm not 100% sure, but I think before I upgraded firmware last week, it didn't say "no IR" - my notes show that I had

but I still was not able to use 6GHz in AP mode then.

fakemanhk commented 1 month ago

In your hostapd.conf, you don't need to config something like ieee80211ax=1? How about ht_capab & vht_capab? I guess you have to tell it?

morrownr commented 1 month ago

Without your full hostapd.conf, we are more or less guessing.

Do you know if it is possible to use this device in AP mode on 6 GHz?

It is. The users that I am aware of that are using adapters with the mt7921au chip are mostly in the EU, with country codes such as FR and DE. I have done some digging but I'm been too busy to figure out why this is not working in the US. This is why my example hostapd.conf got WiFi 6 is only using 5 Ghz:

https://github.com/morrownr/USB-WiFi/blob/main/home/AP_Mode/hostapd-WiFi6.conf

You might take a look at the following issue:

https://github.com/morrownr/USB-WiFi/issues/431

Near the bottom you will see information posted from a user that is using a mt7925 chip based M.2 card to setup an ap with hostapd. The information is detailed and appears to work but that is the next generation of chip and no usb wifi adapters are available yet even the driver is in the kernel and has been since 6.7.

ffund commented 1 month ago

Sorry about that, I added the full hostapd conf below.

Thanks for the tip about this adapter working in FR and DE, that is very useful to know. And the pointer to the related issue is also very useful. I appreciate your help!

@ffund

vht_oper_centr_freq_seg0_idx=42

he_oper_centr_freq_seg0_idx=42

I do not think these settings are correct for band 4 (6 GHz). I think the number should be 39. You might want to look at my WiFi 7 example since it is for band 4:

https://github.com/morrownr/USB-WiFi/blob/main/home/AP_Mode/hostapd-WiFi7.conf

That WiFi 7 guide has not been tested by me yet, which is why the status is listed as alpha. I think it will work or is close.

This WiFi 6 and 7 stuff is compliated. Remember back in the simple WiFi 4 days?

fakemanhk commented 1 month ago

I guess OP can try to find a machine with OpenWrt and create AP with 6GHz then get the config and compare.
