We are going to need way more information to help you. What device is this? How is it configured?

That is radar in 5ghz channel 100

ok, whicih exactly one?:

here is logread: with some details of kernel and hostapd.

at the end i added more logging and i got this:

so card is wifi7 be 160MHZ attempt:

is it wrong board-2.bin / firmware or ath10k driver issue that channel is not supported, and copex wendor say it is!!!

ath12k us flaky, examine iw list whether it claims to support 160 wide dfs scan

14

it seems it is hardware issue:

Why You Can't Use 160MHz

  1. VHT Channel Width Restriction (Fatal)

Explicit statement: Supported Channel Width: neither 160 nor 80+80

Impact: Hardware physically cannot bond channels beyond 80MHz

  1. Extended NSS Missing (Secondary Issue)

VHT extended NSS: not supported

Required for 160MHz spatial stream operation in 802.11ax

  1. Stream Limitations

Only 1-2 spatial streams supported (inadequate for wide channels)

No support for RU puncturing (required in DFS regions)

15

Please stop, persistent lies will not bring support to YOUR frankenstein mashup driver.

16

there is no intent from me for lie.
board-2.bin is given from Compex via seller of the wifi module.

If any of you know that i'm mistaking about 160MHZ for this card on ac/ax/be 2x2 spatial stream, please say so and prove it. i would be more then happy to be wrong. Otherwise i will return this card back.

For me is the learning curve, and please include your knowledge and experience to help others, like i'm doing for community. back.. Giving them my test results and reasoning to them.

Sorry for any misunderstanding.
Kind Regards,
