Hostapd and wifi 6e

doudootiana · March 3, 2023, 10:26pm

Hy.
I tried to use hostapd with a channel in 6ghz

The card wifi is a rz616 (mt 7922) with 6ghz :

          Bitrates (non-HT):
                    * 6.0 Mbps
                    * 9.0 Mbps
                    * 12.0 Mbps
                    * 18.0 Mbps
                    * 24.0 Mbps
                    * 36.0 Mbps
                    * 48.0 Mbps
                    * 54.0 Mbps
            Frequencies:
                    * 5955 MHz [1] (23.0 dBm)
                    * 5975 MHz [5] (23.0 dBm)
                    * 5995 MHz [9] (23.0 dBm)
                    * 6015 MHz [13] (23.0 dBm)
                    * 6035 MHz [17] (23.0 dBm)
                    * 6055 MHz [21] (23.0 dBm)
                    * 6075 MHz [25] (23.0 dBm)
                    * 6095 MHz [29] (23.0 dBm)
                    * 6115 MHz [33] (23.0 dBm)
                    * 6135 MHz [37] (23.0 dBm)
                    * 6155 MHz [41] (23.0 dBm)
                    * 6175 MHz [45] (23.0 dBm)
                    * 6195 MHz [49] (23.0 dBm)
                    * 6215 MHz [53] (23.0 dBm)
                    * 6235 MHz [57] (23.0 dBm)
                    * 6255 MHz [61] (23.0 dBm)
                    * 6275 MHz [65] (23.0 dBm)
                    * 6295 MHz [69] (23.0 dBm)
                    * 6315 MHz [73] (23.0 dBm)
                    * 6335 MHz [77] (23.0 dBm)
                    * 6355 MHz [81] (23.0 dBm)
                    * 6375 MHz [85] (23.0 dBm)
                    * 6395 MHz [89] (23.0 dBm)
                    * 6415 MHz [93] (23.0 dBm)
                    * 6435 MHz [97] (disabled)

In a first time, i tried to use a channel in 5ghz :

country_code=FR
interface=wlan1
ssid=doudoo_diagbox
wpa_passphrase=12345678
hw_mode=a
ieee80211d=1

he_mu_beamformer=1

And it works :

Here the error output :

Can someone help me please :)?

Thank by advance

The 6GHz spectrum is a bit more regulated and I don’t believe you can just set the country_code in the hostapd.conf. Can you try setting adding

options cfg80211 ieee80211_regdom=FR
in a /etc/modprobe.d/cfg80211.conf

to see if it helps?

doudootiana · March 4, 2023, 7:41am

Hy
Thank you to answer me

I use a Buildroot Linux, based on busybox.
I don’t have modprobe.d

But in a script on the boots, i launch the command Line : iw reg set FR .

IS it the same result?

jnettlet · March 4, 2023, 7:43am

no it needs to be set for the module. You should also be able to set it using a custom kernel commandline.

doudootiana · March 4, 2023, 8:05am

I load the module cfg80211 with option ieee80211_regdom=FR.

But same result for Hostapd.

What kernel version are you using?

doudootiana · March 4, 2023, 8:18am

6.1

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tag/?h=v6.1

I think it’s compatible with 6ghz.

doudootiana · March 4, 2023, 8:28am

I have tried with wpa supplicant too :

# nano wpa_supplicant.conf
  GNU nano 6.0                  wpa_supplicant.conf
pmf=2
sae_pwe=1

   mode=2
   ssid="doudoo"
   key_mgmt=SAE
   proto=RSN
   ieee80211w=2
   sae_password="12345678"
   pairwise=CCMP
   group=CCMP
   frequency=6015
}

# wpa_supplicant -i wlan0 -c wpa_supplicant.conf
Successfully initialized wpa_supplicant
rfkill: Cannot open RFKILL control device

But i don’t see the wireless network ssid in my smartphone.

A part of the command line’s output : iw phy phy0 info

They are a part HE Iftypes: managed and for the AP mode : HE Iftypes: AP

And there is this int the part of AP :

                HE PHY Capabilities: (0x0420ce120000a000000c00):
                        HE40/HE80/5GHz

So i can’t use 6ghz and he 160mhz in ap mode

Hey there, today I came across your post while trying to set up a 6GHz AP on a NetGear A8000.

Actually the HE PHY Capabilities showing no 6GHz seems to not really be relevant here.
I think you are just missing the op_class setting from your hostapd conf.

I am not done with testing but the following config snipped seems to successfully create a 6 GHz AP:

hw_mode=a
channel=57
ieee80211ax=1
wmm_enabled=1
op_class=131
ieee80211w=2
auth_algs=1
wpa=2
sae_password=password
wpa_key_mgmt=SAE
rsn_pairwise=CCMP

Note: You have to compile hostapd with CONFIG_SAE=y and you need wpa_key_mgmt=SAE because otherwise you will get the error Management frame protection is required in 6 GHz or Invalid AKM suite for 6 GHz.

Hy,
Thank you for your answer.

Thanks to your informations, i can launch Hostapd with 6ghz and 80mhz.

but i can’t connect my smartphone.

here the log of hostapd during connexion attempt :
