Installing Wireless Drivers on early 2006 iMac

Hi Bodhi Community,

I recently installed Bodhi on my early 2006 iMac, and I'm trying to enable wifi.
I don't have an ethernet connection, but I have a laptop that I can use to download/transfer files to the system running Bodhi.

Chip ID: BCM4311
PCI ID: 14e4:4312
Kernel Driver in Use: b43-pci-bridge

I tried to locate and install the firmware / drivers myself, but I don't really know what I'm doing.
I'm not sure how to locate everything.

[Also I cannot install the rfkill package, as it doesn't seem to be included on the version of Bodhi I installed. Not sure if this is relevant.]



Here is additional information about the hardware:
