I just installed Pop!_OS on my Late-2011 and had to manually install broadcom drivers, maybe this will help.

I’m not sure if the first link’s steps were necessary to enable the second step or not. And of course this is for Pop, so the Gentoo equivalent for Pop Shop, but I imagine there’s generally driver compatibility between linux distros?
