I've installed OpenWRT 19.07.2 for XiaoMi-R3P and found there is an option for 160MHz.
I selected this option and set the channel to 36.
When I used my intel ax200 connect to it, I saw 1.7Gbps in Windows 10.
But I could only see 1.7Gbps for RX and 867Mbps for TX in OpenWRT.
So When I downloaded some files from NAS, I could only reach about 60MB/s.
Can I use 160MHz with XiaoMi R3P for TX?
