Right,
The reason why this fix is not applicable to some because they 'clearly have another problem' or 'cant follow the non official representative of MSI's instructions' is because the information is half baked and theres some insistance that as admins they are absolutely correct. Despite following the various different instructions and bad work arounds here, i have still constantly had the issue of dropouts. Its not another issue, its not windows, its not my hardware, its exactly the same problem that admins here claim to have found a solution for, that they havent fixed. Ive finally completely smashed it out on my machine and have found additional clues to the problem on my MSI GE62 2DQ Apache - The SOLE issue i have with this wonderful machine has been the god awful killer ethernet drivers.Why the f some clown thought it would be a good idea to have a hard wired ethernet port that disconnected will still interfere with a connected wifi network is beyond dumb, and anyone who thinks these types of devices ACTUALLY increase any network traffic flow must be about 12 years old. Even the theory is suspect... but i digest. I dont use a wired ethernet connection at all, i use WiFi exclusively, so to have an ethernet device cause issues with my wifi network p****s me off to no end.
First of all - Remember its actually an ATHEROS AR8161 PCI-E Gigabit Ethernet Controller (NDIS 6.30) - This is what it will display directly in device manager WHEN YOU HAVE CORRECTLY FIXED THE ISSUE
OTHERWISE IT WILL KEEP ON DISPLAYING AS A KILLER ETHERNET DEVICE AND WILL REMAIN NON FUNCTIONAL.
Heres the poop -
Disabling the ethernet in your device manager doesnt stop the dropouts. It DOES however result in faster and sometimes even instant reconnections. This is sketchy tho.
I have no idea what this killer cleaner stuff does, as it seemed to do literally nothing that using the standard windows 'uninstall program' function does. It doesnt remove keys or drivers, only the killer suite. That is all.
Heres how to fix it, so it actually works.
Go to the atheros website and download the suggested standalone drivers, ive given you the device name above.,
UNINSTALL the killer suite using the programs and features menu NOT killer cleaner. (didnt make any difference at all whether i used this or not. i suggest dont use it because i know my steps work)
UNINSTALL the device in device manager, checking the box for deleting the drivers. I find at this stage, im still connected to the internet, as at this stage your wifi card is working exactly the way it should, as a standalone device not connected by software to some half arsed rebranded network card. DISCONNECT from the internet. DO NOT go into airplane mode or anything. Just disconnect.
HERES THE PART THE ADMINS ARE MISSING
REGEDIT - Do repeated searches for 'killer' and 'e2200' - D.F.E. (Delete Effing Every) single key you find with either of those terms in it. ALL KEYS LISTING KILLER OR E2200 NO EXCEPTIONS. THIS IS HIGHLY IMPORTANT. IF YOU DO NOT DO THIS, THEN EVEN IF YOU 'SUCCESSFULLY' INSTALL THE ATHEROS DRIVERS IT WINDOWS WILL A) - STILL LIST YOUR DEVICE AS KILLER ETHERNET AND B) - STILL ATTEMPT TO OVERRIDE YOUR OEM ATHEROS DRIVERS WITH RIVET/KILLER NETWORKS MICROSOFT SUPPLIED DRIVERS. - DO NOT RESTART AT THIS STAGE. Youll also notice when you read some of the notes on the registry keys something called 'Rivet networks' appearing - This also appears to be important but more on that in a moment.
THEN - Scan hardward for changes in device manager. Your device will now come up as a generic unknown ethernet device, THIS IS GOOD
Right click on the device not working - Properties - Update driver - Browse my computer - Let me pick from a list of drivers - Have disk - Locate the files for the drivers you just downloaded, and select the device i listed above **GO THROUGH IT IN THAT ORDER OR IT WILL STILL INSIST ON AUTOMATING THE PROCESS AND WILL RE-INSTALL THE DRIVERS YOU TOLD WINDOWS TO UNINSTALL AND DELETE, AND NOT THE DRIVERS YOU ARE TELLING IT TO INSTALL**
You will then see in your device manager - A Qualcomm Atheros AR8161 entry instead of Killer e2200 and youll very quickly find that you no longer get any dropouts. I did this last night, and have not had a dropout or connection problem since.
A FURTHER OBSERVATION - I then fired up my laptop this morning to keep an eye on whether this has worked and found that my computer had 'Failed' an update..... Windows has again, ATTEMPTED TO OVERRIDE MY DRIVER INSTALLATION by attempting to install what seems to be called some 'Rivet Networks'

so im guessing this is what micropoo are using to insist their software needs to be installed. Ill now have to find a way to block that from ever happening again so i can maintain some functionality during an update cycle. Ive never trusted an OEM with new drivers.
So, now you have the actual lowdown on why A) this problem was FAR from 'Solved' in these forums and B) what the issue is and how to fix it.
_NOW_ the problems are fixed.
Have a nice day.
