new and want to setup an archer c7

[snowstark]

Hello, I found the installation guide here http://www.gargoyle-router.com/wiki/dok ... nk-install

and the download page here http://www.gargoyle-router.com/download.php

but I am absolutely lost as to which file to download. Its a huge page of blue clickable download links and it says "To replace the original TP-LINK firmware select the factory.bin download." but I see dozens of files that end in factory.bin

how do you know which one to use? I verified that I am using currently:
Firmware Version:
3.14.3 Build 151014 Rel.49676n
Hardware Version:
Archer C7 v2 00000000

Did you try searching for the word "archer" on that page to see if that narrowed down the list for you?
