Netgear R7800. Wifi 6 and beamforming?

Installing and Using OpenWrt

Continuing the discussion from Is Beamforming active by default?:

I quoted this from Is Beamforming active by default? - #11 by fodiator

Does the Netgear R7800 or Zyxel NBG6817 support Wifi 6 with Openwrt? AFAIK it does not.

My 2nd question is re beamforming.

root@R7800:~# grep vht_capab /var/run/hostapd*.conf
/var/run/hostapd-phy0.conf:vht_capab=[RXLDPC][SHORT-GI-80][SHORT-GI-160][TX-STBC-2BY1][SU-BEAMFORMER][SU-BEAMFORMEE][MU-BEAMFORMER][MU-BEAMFORMEE][RX-ANTENNA-PATTERN][TX-ANTENNA-PATTERN][RX-STBC-1][SOUNDING-DIMENSION-4][BF-ANTENNA-4][VHT160-80PLUS80][MAX-MPDU-11454][MAX-A-MPDU-LEN-EXP7]

But

root@R7800:~# grep -r beamform /tmp/run/
no result

So do I have to add config lines in wireless?

These are ipq8065 devices with qca9984 wireless chipsets, 802.11ac/wave2 (wifi5), the hardware does not support 802.11ax (wifi6, for that you'd need to look at ipq807x with qcn5024/ qcn5054 wireless).

I don’t believe so - at least no evidence for that in my wifi6 devices. See the original thread for rationale.

With my wifi6 devices I see always something like

root@WSM20-K0:~# grep -r beamform /tmp/run/
/tmp/run/hostapd-phy1.conf:he_su_beamformer=1
/tmp/run/hostapd-phy1.conf:he_su_beamformee=1
/tmp/run/hostapd-phy1.conf:he_mu_beamformer=1
/tmp/run/hostapd-phy1.conf.prev:he_su_beamformer=1
/tmp/run/hostapd-phy1.conf.prev:he_su_beamformee=1
/tmp/run/hostapd-phy1.conf.prev:he_mu_beamformer=1

root@AX53U-S1:~# grep -r beamform /tmp/run/
/tmp/run/hostapd-phy1.conf:he_su_beamformer=1
/tmp/run/hostapd-phy1.conf:he_mu_beamformer=1

Please note, the WSM20 contains he_su_beamformee while the AX53U does not. Both devices are not configured by me re beamforming.

Note: Upgrading the AX53U to 23.05.2 and a lot changed with beamforming. Looks now similiar to the WSM20.

The R7800 or Zyxel NBG6817 are not Wifi 6 devices, but Wifi5 only.

As quoted above, there is no result re beamform with root@R7800:~# grep -r beamform /tmp/run/

The R7800 is used as Upstream WDS device with 2.4GHz and local AP with 5GHz. I am very unsure what I should try.
