Well, all I know is that with secure boot enabled there was no wifi to
be had.
Anyway, I blacklisted bcma now and things are looking much more promising.
But I'll use it for another 12 hours first just to make sure it actually
works properly now.
Thanks for the tip!

Yes, wifi is correct and works perfectly on two other Fedora laptops and

Before I installed broadcom-wl and disabled secure boot, WiFi did not
work at all by the way. It was installed following this:

Don't bcma and wl fight with each other? Not sure.
I don't get the disabling of secure boot in the post you cite. While
the post was for F22 and there may have been issues with secure boot
and F22, secure boot should only affect the boot loader--not the kernel
that's being loaded. I could be wrong on that...I don't profess to
understand UEFI fully.

Nothing particularly interesting in dmesg:

Since only proprietary driver exists for this card, should I even bother
debugging (how?) or is all hope lost? Wifi is super slow (100KB) and
drops constantly.
Can you verify that the thing is connected to the correct wifi network,
on an uncluttered channel? Are you certain you don't have a different
Broadcom driver (e.g. b43 or bcma) loaded that might conflict?
