Does Asus RT-BE86U purchased in US will allow Tx power adjustment? I have it working (386.14_2) on AC86U, probably because it is Chinese market router, or is it working on US market models too?
Thanks!
You can't exceed the preset regional limits though. The routers come with Performance setting by default, usually maximum power, the Tx Power adjustment is eventually reducing the power and the number of streams (Power Save option is 1-stream only).
Only Power Save option is limited to 1-stream based on experience with different model Asus routers. I don’t know if the same applies to 6GHz band or if this behaviour was changed in later models. Easy to test.
