yeah it's forced to 160mhz only. wondering if it's due to a setting on the AX200 wifi driver itself
 
yeah it was already forced on 160mhz since day one.

19dB is very low power for 5Hz ... it`s 89mW.

p.s. try 149-161 channels at 80Mhz, it will give ~ 24 dB + antenna / ~300mW

ok, I'll give it a try. I can roughly understand your charts. but how to do see my charts? LOL it's nowhere as comprehensive as yours. I have a RT-AC3100 also. I am wondering what's its like

for chn100 i get

maybe something has changed since 2020. check the current power through the command line, it will be more reliable this way

22dB - 158mW

the power may differ even on adjacent channels, for example 100 and 102/104

Are you in a noisy WiFi neighborhood? If so, enable OFDMA DL only.

The benefits of OFDMA are it creates signal diversity in a noisy radio environment. Diversity helps to counter the effects of co channel interference.

hate to diy up old topic.. but I am also having the same problem on my ax88u
I still cant enable AX @2409/2409.
it's only when I turn off AX/160mhz and switch to AC/160 then I managed to secure 1733/1733
AX/160 only gets me 2409/229

the thing is all my 4 AX laptops are doing 2409/229.
hi

did you find a solution?
I have the same problem with my AX86!
My 2 PCs (AX200 and 210) can' t go up than 229 Mbps with RX rate in AX mode (ok in AC mode)
on PS5 the upload rise at 5mb/s

no problems with TX rate

driver PC: intel 22.50.1.1
driver router: merlin 386.2_6

thanks a lot
