While we can’t walk you through your exact router setup, we can highlight the key considerations that go into configuring Quality of Service rules. RELATED: Turn Your Home Router Into a Super-Powered Router with DD-WRT streaming video over web browsing), and others offer granular control over nearly every aspect of the process. Some have you specify what kind of services you want to prioritize (e.g. Some routers have Quality of Service settings that are as simplistic as allowing you to prioritize the traffic from one computer over another. There are hundreds of different routers out there with wildly different firmware and capabilities.

How to Enable Quality of Service on Your Router Networks with a Quality of Service model applied will prioritize, as you tell it, certain applications, services, and/or users over others so the important things (Netflix, Skype calls, your Xbox Live connect, etc.) have the most bandwidth and the best ping time. Quality of Service, to return to our hospital analogy, is like a very competent triage nurse who directs patients to the right doctor in the most efficient way: the guy who just got run over by the truck will get multiple doctors and the guy sitting there with the nail stuck in his hand from the bird-house-project-gone-wrong will wait a moment and get a single doctor when he’s seen.
QoS visualized with a service-based priority model. The router is doing its best to share the available bandwidth between the two services, not really considering which is “more important”. This means if you’re on a Skype conference call with your boss and your kids start watching Netflix, the quality of your Skype call can drop. The same thing happens on your network at home–bandwidth is given out as needed, without much regard for what each application is doing. You can see how, in short order, the hospital would be a bogged down mess and high-priority patients wouldn’t be getting high-priority care. Somebody else shows up with a broken arm? They get a doctor too (but if it’s getting really busy pretty soon people are sharing doctors and nobody is getting particularly speedy care). Someone just got run over by a truck? They get a doctor immediately too. Accidentally shot your hand with a nail gun during a DIY project? You get a doctor immediately. On a normal network, the triage nurse is indifferent to the condition of the incoming patients and simply assigns them to any available doctors, progressively spreading the staff of the hospital thinner and thinner with no regard for the severity of the patient’s situation. The patients are the different applications, and the triage nurse is the router. It may help to think about Quality of Service like this: Let’s pretend, for a moment, that your Internet connection is a hospital where the available bandwidth is the number of doctors available to treat patients.
Quality of Service is an excellent and underutilized tool that allows you to train your router to divvy up your available bandwidth between applications. With good QoS rules, you can ensure that your streaming video doesn’t stutter because a big file is downloading at the same time, or that your work laptop isn’t sluggish when you’re trying to meet that last minute deadline while your kids are playing games online. The Quality of Service feature on your router lets you prioritize the things you care about, so they happen faster than the things you don’t. Streaming HD video or having a stutter-free Skype call is probably more important to you than downloading a big file.
