When installing any kernel other than the standard one, the drivers do not work, installed it through the Application Center
EOS 6 Gtx 850m ASUS g550 driver 460,470
Not sure if that is the same case, but I had to install linux-headers-generic-hwe-20.04
(I already had linux-image-generic-hwe-20.04
installed) in order to have my Broadcom wifi driver bcmwl-kernel-source
automatically reinstalled for each new kernel update.
Before that, bcmwl-kernel-source
was installed only with 5.4.x kernel.
Maybe I'm way off, but it's safe to try.
