Multiple QCN9074 Card

They are from 8devices.com. I have one of each versions 2.4,5 and 6 ghz.

2.4 ghz looks mostly fine i get decent internet speeds but 5 Ghz isn't stable. I once were able to connect to it using my laptop but later disappeared. Restarting the adapter on GUI usually makes it show up again. Also, my phone doesn't see 5 ghz at all. In theory it has Snapdragon 8+ Gen 1 so up to wifi 6e everything should just work. When i connect through 5 ghz, internet is slower as well.

Beside that i have below in dmesg. Not sure this is related.

I will do more testing, check the antennas etc.

You do have 5V power supply for them connected?

Yes I do. I'm not sure if it would work without it at all. It might not be the root issue but i use below diplexer to reduce the antennas required for 2.4 and 5 ghz modules from 8 to 4. I will directly connect antenna to 5 Ghz and will try.

That shouldnt break anything, can you post the whole log with 2 cards(Maybe they forgot to fuse the cards again)

I read some reddit posts about fusing thing and it is basically locked to 5 ghz in that case. I made specifically asked them about it and they said their modules are properly fused. Is below enough?

As a side note you know this probably, i'm communicating with their support team and they said Qualcomm provides proprietary drivers for their chipset which is arm and it needs licensing. So, even if i get, it it would be useless for me.

Hm, failed to enqueue rx buf: -28 is just screaming that something is not right.
