ZyXEL NWA50AX Pro: No 3x3 MIMO

Hello,

the ZyXEL NWA50AX Pro is advertised with 3x3 MIMO in the 5 gigahertz band. My checks with iw phy phy1 info show only two available streams. I flashed openwrt 23.05.03 just after unpack. That's why I'm wondering whether I shouldn't have installed available firmware updates from Zyxel beforehand?

Agreed, it shows as 3T3R on 5GHz:

What client are you testing the 3x3 with?

Tested with WIFIman on Pixel 6a

Pixel 6a is only MIMO 2x2:

  • Wi-Fi 6 (802.11ax) and 6E (6GHz) with 2.4G+5GHz+6GHz, HE160, 2X2 MIMO
    Pixel 6a is Wi-Fi 6E capable (Wi-Fi 6E is not enabled in Taiwan, Japan, and Singapore)

Have you got anything that supports MIMO 3x3, most WiFi6 clients are only 2x2, the last WiFi5 client I had that supported 3x3 was a Pixel 2 European model.

Ok, but WIFIman shows peer capabilities, not connection status. For Belkin RT3200 it shows MIMO 4x4 on the same Pixel 6a.

I don't know of any device that I own that has at least 3x3, but if I understand correctly the AP should be able to talk to a 2x2 device and another 1x1 device simultaneously.

So if you connect the NWA50AX Pro to the RT3200 on the 5GHz wireless, what MIMO is reported by the NWA50AX Pro, 3X3 or 2X2?

My WAX206 and MR90X both show 4X4 MIMO on WIFIman

Thank you for your support, I've to try that out. But I thinks this will not change anything as the iw list output is also about capabilities, not connection status.

Output for RT3200 shows 4 streams in ap mode. (the NWA50AX Pro is not connected as a client)

My only test device with 3X3 MIMO is my MikroTik WAP AC 1st Gen, which has 3X3 5Ghz WiFi5 MIMO, this correctly connects via wireless to my 4X4 MIMO devices as 3X3 MIMO 1300/1300 which is the correct rate for 3X3 WiFi5 @ 80MHz 256 QAM.

But how many streams are reported by iw list on your devices? So I think the question is if the advertised 3x3 MIMO is unlocked by a ZyXEL firmware update or the propagated specs are simply incorrect?

3 spatial streams are reported.

There's only 2 firmware versions for the NWA50AX Pro, released in April and October last year, the unit should be capable of 2.4Gbps over 5Ghz AX although that does not make sense as that would be only as capable as the GL-iNet Beryl AX which is a 2X2 MIMO device.

After carefully reading the specifications again it becomes clearer. The device is 5 GHz: 3x3:2SS, so although has 3x3 antennas it can handle (only) 2 spatial streams. Sorry for confusion.
