STA-to-STA OFDMA issue?

[souflyy]

Hi guys, sorry to bring this topic up again, but my question fits perfectly into this topic.

Is this issue still present today when OFDMA / 802.11ax + MU-MIMO is enabled?

I have a GT-AX11000 and I want to use Playstation 5 Remote Play to stream to my Surface Pro 8 (both connected with Wifi 6), and it runs very very bad.
I have read all your tests and I think the reason is that the PS5 and Surface is up and downloading at the "same" time, and therefore the bad performance.

I tried it also with OFDMA and MU-MIMO completely disabled, then it runs surprisingly good, but what is the benefit then, that I have a monster Wifi6 router where I have to disable the OFDMA and Mu-MIMO?

Even with OFDMA DL-only I get some little stuttering during using remote play.

Thanks all

but what is the benefit then

The reality - in typical home environment with mixed N/AC/AX clients the benefit is minimal to none. Mostly used by home router manufacturers for marketing purposes. Your monster router is mostly non-functional Gaming plastic with RGB lights and about $100 hardware inside with somewhat working firmware.

Thanks for your input, unfortunately, this is what I already expected

I am using my network like this:
2g = all my IOT and legacy stuff
5g1 = all my n and ac devices
5g2 = ax only

So I thought that I can have the full OFDMA benefits in 5g2.
But I am not scared to disable those things again, if they are known to be buggy.

Primary I bought the router to have 4x4 MIMO, because I have some 4x4 devices at home.

For the professional settings:
- Implicit and explicit beamforming seems to work ok, I can see a benefit in signal quality and I see in Wifi logs more throughput in theory, but I have not tested if the throughput gain is real.
- Airtime fairness I have off, because, I had some troubles with some of my devices (connection loss), and I think this is no Wifi standard?
- MU-MIMO I have actually on, because I have a lot of 2x2 MU-MIMO devices, but I dont know if it will harm or help, or if it is even working.
- OFDMA I have set to OFDMA / 802.11ax + MU-MIMO, because I have some ax devices, but it looks like, that this setting is harmful.

What professional settings do you guys use in your home environment?

Thanks!
