Hi, I search for a solution on other threads and no lucky for now.
After updating ubuntu from 19.10 to 20.04 (LTS) my Wifi network is not working anymore. I found that iwlmvm kernel module is not being loaded in 5.4 kernel. When I turn back to kernel 5.3 everything is working good.

$ lsmod | grep iwl

Most of them DKMS modules I've installed in a try to make it work, but before that there are not most of them.
It's missing iwlwifi modules (have not found on 5.4)
find /lib/modules -name "iwlwifi*"

How can I generate this module, not compiling kernel manually?
