Hi, could you confirm dkms modules have been built and installed? Looks good for me from my side except I don't have this bcm chip:
$ dkms status bcmwl, 6.30.223.271+bdcom, 5.4.0-45-lowlatency, x86_64: installed bcmwl, 6.30.223.271+bdcom, 5.4.0-47-generic, x86_64: installed bcmwl, 6.30.223.271+bdcom, 5.4.0-47-lowlatency, x86_64: installed bcmwl, 6.30.223.271+bdcom, 5.4.0-48-generic, x86_64: installed bcmwl, 6.30.223.271+bdcom, 5.4.0-48-lowlatency, x86_64: installed Besides, it seems stable patch broke OEM kernel interface again.
