Hi,
I've narrowed down my problem on latest snapshot and found out, that if I do 160 mhz on 5220 mhz in ax mode between Ap 1 (wds main) and ap2 (wds client), it does NOT work. No data gets through the link, but both ap's tell they are connected fine. I can also see "associated", "authenticated" log lines on both so I'm sure they connect. But I cannot get a single packet through from ap1 to ap2 and vice versa, e.g. Ping.
Workaround: If it switch to ac mode with 160 mhz, the connection is established like before and I can get data through, e.g. ping the other ap.
Is this a driver bug?
Both devices are this:

Your router does not support 160mhz wide channels
I respect your knowledge, but are you sure?

4t4r \80mhz means 2400mbp, as per xiaomi advertised specs. Maybe it does 2t2r 160, not sure, not advertised. Should be somehow visible in iw list

So, what do we have in regard of the hardware support?

Try auto channel, might be radar signal detected in default one somehow.
Catfriend1:
HE160/5GHz
Setting HE160 ch100 or ch52 in LUCI works, but using WifiAnalyzer on my 160 MHz capable phone reveals, it's still doing 80 MHz after the radio1 AX came up.
Whatever I do, it is not doing 160mhz if selected, but 80mhz instead.
The device is capable of 160 mhz according to https://www.gizchina.com/2020/05/09/xiaomi-aiot-router-ax3600-to-get-a-major-upgrade-adds-160mhz-dynamic-bandwidth/
So I guess it's an openwrt ath11k driver problem?
I use 160MHz with Channel 36 in Germany without problems.
Tschau
Could you please use a wifi 6 capable phone with the app WifiAnalyzer to verify? Or alternatively the channel diag chart of FritzBox 7590 ax (or higher) shows the channel width. I have taken a lot of time today to measure using iperf3 between two ax3600 units and they "in reality" only send/recv on 80 mhz, no matter if I set 80mhz or 160mhz in luci. The measured speed is also the same for both settings like in 80mhz mode.
To check if the app works right, I've temporarily enabled Fritzbox' wifi 6 ax with 160 mhz channel width and the app immediately showed it.
The 160MHz channel is displayed on all my capable devices. Perhaps you have a radar signal nearby...
Tschau

Thank you.
Indeed, now my phone reports 160 Mhz being sent by the AP. As soon as I switch to mesh, it's 80 MHz. I'll investigate further next time and report back, if I find some issues. Maybe I can do AP-STA with 160 MHz instead of mesh. Mesh also breaks, when DFS detects radar, I hope it can be better with auto channel and AP-STA.
