What kext do you need on HP EliteBook 2570p for Wi-Fi?

Question

WiFi

I have a laptop in my hands.
I decided to install a new OS X Yosemite on it.
Installed according to this manual .
And everything would be fine ... the system got up and works like clockwork, but the network is only available through the Ethernet tail :( And as you know, a laptop without wi -fi is not very suitable for work ... what I have is:
Broadcom BCM43228 802.11n Wireless Network Adapter
I dug up and down the Internet, but I couldn’t really find any information :(
Colleagues, I ask for your help ... tell me, please, does the correct kext exist in nature for this card And if so, please tell me where to look.

Answer 1

I would dig towards the port from open source * nix drivers for this chip. For example,

the AirPortBrcm4360.kext is dervied from the open source Broadcom driver: brcm80211 - Linux Wireless. Broadcom says:
To be done for softmac driver
Add support for more chips, including (near term) BCM43227, BCM43228, and BCM4331. Support for additional new chips to follow.
Interestingly, the driver supports 802.11 ac, not documented
At this time, those with Asus Ivy Bridge wireless don't have a solution, however, those purchasing an Asus Haswell (Deluxe) motherboard with ac wireless will own the ideal Airport solution (dual band 802.11ac+abgn and BT4.0).
Three ways to inject non native Broadcom supported Device_IDs: 1. AirPortBrcm4360.kext/Info.plist edit, 2. dsdt edit or 3. a helper kext (often called Legacy).
