[Solved] Wireless interface not showing up

I'm currently trying to set up wifi on my mid-2012 MacBook Pro and I'm running into an odd issue. Through lspci I discovered that my network controller is BCM4331, corresponding to b43-firmware. I installed this since it is explicitly mentioned to use b43-firmware and not one of the other two though. I must be missing a step though because after the install, I still can't find my wifi interface. "ip a" only gives me the loopback interface and ethernet.

Thanks in advance!

Re: [Solved] Wireless interface not showing up

My first suggestion would be to check if the module is loaded with lsmod. You might wanna add this module to your mkinitcpio.conf so it can be loaded in early boot. There's a caveat though, if I remember correctly, there's a b43legacy besides the b43 driver. I guess you should check which one is the correct for you. There's some good information on the Broadcom wireless page on the wiki.

Also, search for [Ff]irmware in your journal.  It might be that the system is missing the required firmware blob.
