Why does about this mac say all the PHY modes are supported but not the wiki page? Is it because they are different drivers?.Is there a macOS BCM43xx driver and a linux BCM43xx driver?.How do I use this information to figure out if my wifi card will work?.However, following a link to the Comparison of open-source wireless drivers wikipedia page works:

Looking through the existing Linux drivers and Cmd+f for BCM43xx turns up nothing.

Which terms in the output of lspci -k correspond to the output from 'About this mac'?.

Is the Firmware Version another word for a Driver?.

I think the two important pieces of information are the Card Type and the Firmware Version. Subsystem: Intel Corporation WiFi Link 5100 AGN

The following example is given: $ lspci -kĠ6:00.0 Network controller: Intel Corporation WiFi Link 5100

What drivers do I need to make it work?įirst I went into the 'About this mac' menu to get some information about the network interface (is that the physical network device?): en0:Ĭard Type: AirPort Extreme (0x14E4, 0x112)įirmware Version: Broadcom BCM43xx 1.0 (7.21.171.68.1a5).

What is the physical wifi device on my machine?.

My goal is to get a better understanding of how to figure out: The first part is to identify and ensure the correct driver for your wireless device is installed I'm running macOS on a macbook pro from late 2013 but am reading the Arch wiki on wifi configuration and focusing on the first part:

Wifi link 5100 driver update 2017
