Wallys DR9074-6E(PN02.7) QCN9074 refuses to work on 6GHz band

[Nagarajan Maran (QUIC)]

Hi Mariusz,

We are looking into this issue. It seems that this error can occur when the given frequency is not present or when the given frequency is disabled.
To further analyze the issue, could you kindly let us know the output of the below commands during failure case.
     1) iw dev
     2) iw phyX channels

Also, could you kindly send the WiFi driver boot up logs with "debug_mask=0x212" enabled during insmod of ath11k.ko module.

Thanks,
Nagarajan M.

Hi,

As support for QCN9074 got better I went ahead and built a 6E linux based AP. Dell R720 server x86 running Linux s4 5.19.0-23-generic #24-Ubuntu SMP PREEMPT_DYNAMIC Fri Oct 14 15:39:57 UTC 2022 x86_64
x86_64 x86_64 GNU/Linux.

My issue is that I cannot get it working on 6GHz bands but it works fine on 5GHz. I bought 6E version  and since this is a single band module it cannot be both 5G & 6G and linux driver does not agree with it being 6E version:

I am using the latest firmware files from ath11k tree. Is there any special firmware to force this to 6GHz? I read somewhere board_id determines which one it is and 255 disables 6GHz but I miss more data on that.

        (5945 - 7125 @ 160), (N/A, 30), (N/A), NO-OUTDOOR, AUTO-BW

It works fine in 5GHz but this is not what I purchased it for, so I am puzzled if this is something in software or I was sold wrong hardware.Is there a specific board-2.bin for 6GHz? Since the 9074 chip is the same in all versions perhaps this is a software hiccup.

Any clues are welcome.

Mario
