When I upgraded from 6.6.10 to 6.7.0 on my Dell Studio laptop, the WiFi disappeared.
I downgraded back to 6.6.10 and it worked again.
So, there is some kind of a bug in the kernel 6.7.0.
I use 6.7.0 on my Dell Optiplex desktop computer.
But that computer doesn’t use the WiFi, since it is cable connected.
I use 6.7.0 on a handful of Dell laptops of different types,
but it is only the Dell Studio laptop that has this problem.
This has happened before, when I upgraded from 6.3.12 to 6.4.2.
When I downgraded back to 6.3.12 it worked again.
The problem repeted itself again, when I upgraded from 6.4.12 to 6.5.0.
When I downgraded back to 6.4.12 it worked again.
The Dell Studio laptop has a Pentium Dual CPU T3400 @ 2.16 GHz.
One physical processor, 2 cores, 2 threads.
It has 4GB of RAM.
I use the XFCE version of Manjaro.
Basically, the upgrade script for new kernel branch is somehow buggy. You have to install the kernel headers first, only the headers. Then you can install the kernel normally and everything will work after restart.
Can someone fix the upgrade script bugs?
I am a user of Linux, not a programmer.
I use Pamac to upgrade and if the kernel upgrade doesn’t work I hope some one will fix it.
