Follow up to : Xiaomi AX3600: 160 MHz not possible on ch36, radio1 (IPQ8074 802.11acaxn)
So, most settings didn't work or were not compliant to regulatory means. What is accepted by the driver is the following setting:
- Country: DE
- Channel: 52
- Mode: AX
- Txpower: 23
For radio1 (wifi 6). This works fine and has 1 minute DFS CAC scan time till the radio comes up.
