AX411 - $18.75

[follower]

I tried to capture some more info on how DCT works but, the 2nd band when in use isn't providing much info.

Why don't you hide MACs?

Why don't you hide MACs?

Because they're layer 2 and don't matter.

Found a quirk in :Linux upon doing a reboot for a kernel upgrade. Not sure what I was playing with before that caused it but, I might have been cleaning out some old firmware sitting in /lib/firmware or some other update. Anyway... the AX411 uses slightly different modules than the AX21x versions. They use the GF4 option instead of the TY that the others do. Thinking they were the same I looked up and down for the earliest AX210 package with the -39.ucode being the first I had recalled seeing in the firmware directory, I couldn't find it anywhere and then started playing with different kernel versions thinking it might be embedded in one of them. I stripped out the ucode files from the directory and imported only the GF4 modules

Maybe it was deleting the pnvm file during some tinkering and then the reboot was just coincidental w/o having put the file back. There seems to be something embedded in both versions of the card though making them look for version 72 of the firmware but, that doesn't exist anywhere but, 73 does but, they won't use it and fallback to 71. SMH @ Intel on this one. Since it's not a well documented card still at this point HTH someone searching google or the forum in getting it working on their system.

iwlwifi — Linux Wireless documentation

Kernel 5.14 it seems is what’s needed at minimum for 411/211.

Yeah, I've been running 5.19.x though.i tried loading 5.14-18 versions but had this weird no mac error. I think between deleting all of the ucode and pnvm files and hard booting it dislodged the issue because I copied in the ucode files and did a modprobe and the error indicated it wanted the pnvm file to activate and from there it was flawless again. There's sometimes odd issues that appear on soft reboots though that don't with a hard reboot.

Hello does the dct feature work on linux?

Do you need to have both bands use the same SSD?

Is there a manual/page from intel on how to set up this feature?
