After several crashes related to the bad Bigfoot Killer Ethernet software and driver, I decided to dig a little deeper.
Most people will be able to tell you that the "Killer Ethernet" is fairy pointless, I didn't buy the laptop for it at any rate.
It's worse than pointless when it causes system instability and crashes.

After a little research I determined that the "Qualcomm Atheros llama Ke2200 Series PCI-E Ethernet Controller" is actually a "Qualcomm Atheros AR813X/AR815X/816X Series PCI-E Ethernet Controller"
Specifically it's a slightly modified AR8161 Gigabit Ethernet [1969:1091].

As such you can download newer, unmodified drivers from Atheros directly, just google for: atheros+download and visit the first link.
On the Atheros site under "AR816X Family Drivers" choose the "WIN_AR816X" option from the dropdown box.
However, the vendor and device ID won't match, so you'll need to do the following to install it.
Keep in mind that these are raw drivers, they're work perfectly, but include none of the fancy (useless) "Killer" software features.

Lets get started!
Download the file above and extract it to a temporary location.

First, (because removing the killer Ethernet software is part of the goal here) you should go to control panel and uninstall the existing bigfoot killer Ethernet package from "Programs and Features".

1) Head to control panel and open "Device Manager".
2) Under "Network Adapters" right click on the e2200 Killer network card and choose "Update Driver Software".
3) Click "Browse my computer for driver software".
4) Click "Let me pick from a list of device drivers on my computer.
5) Click "Have Disk".
6) Click "Browse"
7) Find the folder you extracted and navigate to "AR813x_AR815x_AR816x_v2.1.0.15_WHQL\Common_Dri\Win8_64"
8) Select "L1C63x64.inf" and click Open, then OK.
9) From the list of drivers choose "Qualcomm Atheros 8161 PCI-E Gigabit Ethernet Controller (NDIS 6.30)"
10) Choose "Yes".
11) Now choose "Close".

In Control Panel your network card will now be called "Qualcomm Atheros 8161 PCI-E Gigabit Ethernet Controller (NDIS 6.30)"
You're now running the latest Atheros driver for your rebranded Atheros AR8161 Ethernet Card. :) 8-))
