3200ACM MU-MIMO

[p3x-robot]

What is the status of the MU-MIMO implementation?

[p3x-robot]

is there anything I can help to make it work?

[p3x-robot]

so are you saying for 3200ACM, just disable kmod-mwifiex-sdio and mwifiex-sdio-firmware and mwlwifi will automatically do it?

[BrainSlayer]

from my knowledge mu mimo is supported. you just need to configure the vht flags correct in hostapd

[p3x-robot]

ciao!
how are you?
thanks so much for replying!
so i delete kmod-mwifiex-sdio and mwifiex-sdio-firmware and configure the vht flags correct in hostapd?
do you know where the vht flags correct in hostapd?

see ya!

[p3x-robot]

ahh and whichi version that supports? lede 17.0.1.2 is enough? or newer?
thanks so much!

[yuhhaurlin]

This feature will be added later.

I found this:

docker@34e9a52707ae:/build/source$ cat /build/source/package/network/services/hostapd/files/hostapd.sh | grep vht
		ac) append base_cfg "require_vht=1" "$N";;

@BrainSlayer Is it where I could set it up the VHT somehow, there is no VHT is hostapd anywhere also.

I found these:

/build/source/package/network/services/hostapd/patches/004-hostapd-Add-possibility-to-send-debug-messages-to-sy.patch
/build/source/package/network/services/hostapd/patches/430-hostapd_cli_ifdef.patch
/build/source/package/network/services/hostapd/files/hostapd-full.config
/build/source/package/network/services/hostapd/files/hostapd-mini.config
/build/source/package/network/services/hostapd/files/hostapd.sh
/build/source/dl/hostapd-2016-12-19-ad02e79d.tar.xz

But all empty with VHT with grep.

@BrainSlayer in the router I found this files:

/lib/netifd/hostapd.sh # has vht
/tmp/run/hostapd-phy0.conf # has vht

root@digi:~# cat /rom/lib/netifd/hostapd.sh | grep vht
		ac) append base_cfg "require_vht=1" "$N";;

root@digi:~# cat /tmp/run/hostapd-phy0.conf | grep vht

Do you know where this could turn it on???
:)

This is it, isn'it ?

[BrainSlayer]

you need to fix the vht_capab info MU-BEAMFORMER etc is missing. but i need to check on my device first which supported flags are returned by the chipset itself. would take some hours since i just woke up

[BrainSlayer]

okay checked it. the chipset does return mu-beamformee etc. as unsupported so the chipset isnt capable of doing mu-mimo or the mwlwifi drivers firmware isnt capable of doing it. @yuhhaurlin may have a answer to it

[yuhhaurlin]

I already told you that MU-MIMO will be added later. 88W8964 is capable to do that, but it needs extra code to let it work. I have no schedule now, but it should be done ASAP.

[yuhhaurlin]

BTW, mac80211.sh will add capability of chip to hostapd configuration file. If you use LEDE/OpenWrt, there is no need for you to worry about it.

How about WDS? Maybe next? Please :-) — You are receiving this because you are subscribed to this thread. Reply to this email directly, view it on GitHub, or mute the thread.

I think WDS will be done first. I have no schedule for these two features, but they will be done ASAP.
