On 6.09 on Ubuntu mate 22.04 for two days now and it works like a charm.
I had major issues with WIFI in Africa and did the fixe pointed on this forum. WHich solved my problem.
I thought I d give it a try to latest kernel to see if it would improve even further.
I don t see much difference on the Wifi side.
My feeling is that 5.15 AND 6.0.9 have gotten much more stable with the intel 12th gen.
I had important freezings for 5 to 20 seconds every two days. Especially anoying when you are in a video meeting!
Now it seems mostely gone with the two kernels since a month or so.
Wifi solved :
