About This File

This version of the driver is not compatible with AppleVTD.


Key Features of the Driver

  • Supports Qualcomm Atheros AR816x, AR817x, Killer E220x, Killer E2400 and Killer E2500.
  • Support for multisegment packets relieving the network stack of unnecessary copy operations when assembling packets for transmission.
  • No-copy receive and transmit. Only small packets are copied on reception because creating a copy is more efficient than allocating a new buffer.
  • TCP, UDP and IPv4 checksum offload (receive and transmit).
  • Support for TCP/IPv6 and UDP/IPv6 checksum offload.
  • Makes use of the chip's TCP Segmentation Offload (TSO) feature with IPv4 and IPv6 in order to reduce CPU load while sending large amounts of data.
  • Fully optimized for Mountain Lion, Mavericks and Yosemite (64bit architecture) but should work with Lion (only 64bit) too, provided you build from source with the 10.7 SDK.
  • Wake on LAN support.
  • VLAN support used to be broken in older versions but is working since version 2.3.2.
  • The driver is published under GPLv2.

I'm losing network access after deep sleep. Would anyone know how to fix it? Using latest driver. This has never happened before.

Hi @Mieze:

                 I'm booting fine with your latest AtherosE2200Ethernet 2.3.3 release. The problem is it only boots with the kext you built and uploaded here. But my system won't boot when downloading your repository and building it with xcode, or with the help of building tools within OC builder or Hackintool.

Here is a pic of the screen. Usually I try to take screenshots within OpenCore but this time I couldn't.
