Kernel upgrade

For those who may be interested or help, I already have the PCI wifi installed and operational.  In the end, go for the longest path and the easiest solution.  In order not to have to touch Kernel or try possible breakdowns, search the websites of different manufacturers for the chips that were integrated in the PCI, with this data I went to the websites of the chips to see which ones had firmware for Linux and for which kernels.  I ended up finding one that fulfilled everything, in my case a Ubit 11AC WiFi 5, with an Intel 7265 chip and it was Plug & Play. 
Thank you very much to all. 
Tommy for when one of your wonderful installation tutorials with the new 5.1 Bullseye kernel?
