This problem is actually mentioned on the wiki, but no solution is even hinted ( here )

any idea where to start to fix the problem?

Re: broadcom wifi not detected by lspci/lsusb

Do you have a regular laptop or a tablet/laptop hybrid? And which exact Broadcom device is it?

Re: broadcom wifi not detected by lspci/lsusb

Which of the drivers did you install? And what Gusar said, some information about what you have would help. How to ask questions the smart way
brcmsmac/brcmfmac    Open-source kernel driver
b43    Reverse-engineered kernel driver
broadcom-wl    Proprietary Broadcom STA driver

This is a regular laptop. A macbook pro 7,1 to be exact.

Sadly, I cannot give any more information as wich exact card it is since it is not detected by lspci.
All I can say is that it previously worked with arch, and that it needed the broadcom-wl driver to do so.

Is this behavior seen after the last upgrade?  What packages were upgraded?

Yes and no:

I actually upgraded my hard drive to a bigger one, this is a fresh install.

Wifi cards in tablets or hybrids aren't PCI(e) or USB devices, but since you have a Mac it should be a PCIe device. Does the card show up in OSX?

i suceeded yesterday in burning an osx install dvd since my old one was broken. I did not perform an install,  but the live environment does not seem to detect the wifi card. I'm starting to think that it simply broke somehow.

That is certainly bad news.  Can you show output of rfkill list? <--- probably won't show anything though

I was thinking physical issues as a possibility too. Either that, or there's some specific firmware/ACPI magic required to activate it, but if that was the case OSX would for sure know of this magic. The card may not necessarily be broken, maybe just not seated properly. So you'd need to open the machine, remove the card and insert it again.
