Seems Canonical have solved this inconsistency, but forgot release update! Kernel changes, discussed here, gets came up in version 5.6 of the kernel and are represented in the last versions of bcmwl-kernel-source (6.30.223.271+bdcom-0ubuntu7). The only difference between 6.30.223.271+bdcom-0ubuntu5 and 6.30.223.271+bdcom-0ubuntu7 is the patch dealing with corresponding changes (/usr/src/bcmwl-6.30.223.271+bdcom/patches/0028-add-support-for-linux-5.6.patch), the one I mentioned before that have to be added (seems already done). The actual bug here is newer kernel letting in mainstream (5.8 > 5.6), without corresponding driver package version. Final solution will be simple enough - just adding latest bcmwl-kernel-source to Focal repository. I just installed it and: --------------------------------------------------- #dpkg -i bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu7_amd64.deb (Четене на базата данни ... 547141 файла или папки в момента са инсталирани.)

Seems something is going wrong with missing function declaration - function "ioremap_nocache", as could be seen in attached make.log. I'm guessing, driver code may need be updated according to the new kernel headers.
