MU-MIMO disabled on 2x2 APs

kessvn — Thu, 22 Dec 2022 08:50:40 GMT

Hello,

I've noticed that MU-MIMO is disabled on the latest version of vSZ:

MU-MIMO is disabled by default in release 6.1.1 on all 2x2 APs like R560, R550, R350, H550, H350 and T350 series.

Why is it? Doesn't it add any benefit for multiple 1x1 clients? Does it consume a lot of AP resources so it is better to turn it off by default?

Hello @kessvn,

Yes, MU-MIMO feature is disabled by default in 6.1.1. It is documented in release notes.

This has been decided after QA Testing with multiple legacy (WiFi-4/WiFi-5) client devices, which would under perform with MU-MIMO feature enabled due to client interoperability issues and outdated wifi drivers.

Hello,

"disabled by default" means we can enable it, right? How do we do this?

Thanks,
Dino

Hello @Dino,

Yes, we can enable it from AP CLI. Below is the CLI commands.

get disable-mumimo : get disable-mumimo <wifi name> {1|0}
-- Get whether disable MUMIMO is set or not.
set disable-mumimo : set disable-mumimo <wifi name> {1|0}
-- Set disable MUMIMO.
