This article seems to say that you need to go get a particular piece of software to achieve the result for gamers. WTF? QoS (Quality of Service) is present in HEAPS of consumer devices; there's no need to go building your own router to do this. In reality, there should have been merely an article titled "How to use QoS/Traffic Shaping to maintain online gaming speed". There's going to be a bunch of people burning a lot of time on this solution when it may already be right in front of them on the router they already own.
