Hopefully this device actually has the CPU power to run QOS at more than 50mbps... the same can't be said of any other consumer router in the $200 price range.
Can you explain that? What's QOS, how much CPU does it take to run well, and why don't other expensive routers have the power for fast internet?
This takes some processing power which not all routers have a lot of.
