when i do an' ip a ' this card does not show?

This card has worked great as a wifi hotspot for our home use for over a year with Bullseye

This card of course does do bluetooth as well.and am thinking something is in a funk here

The only posts i can find on this card is talking about you have to have minimum 5.12 kernel for it to work,,which i done this from backports for Bullseye.

And yes my upgrade done all the firmware update business in the process.

Edit: If i boot back into the previous kernel,,, backport 6.x of Bullseye , the wifi 6 card does work again as expected.
Linux server2 6.1.0-0.deb11.13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.55-1~bpo11+1 (2023-10-08) x86_64 GNU/Linux

Ideas.

TIA
