Yes, moving by small steps is the right way.
Here updated diff which includes only 160MHz, I also spoted one missed point
which related to last non-MIMO fix.
With only this diff my iperf test shows with -P 16:
[SUM] 0.00-30.05 sec 1.76 GBytes 504 Mbits/sec 268540 sender
[SUM] 0.00-30.01 sec 1.72 GBytes 493 Mbits/sec receiver
and unifi confirms that laptop is connected with 160Mhz window and RX/Tx
Rate 1.3 / 1.2 Gbps
Ok?
