I just bought and deployed the GT-AC5300 a few days ago. I'm coming from an AC88U. The GUI is somewhat different. Here's the thing, under QoS (adaptive) in the AC88u you could drag and drop color coded priority levels onto specific devices. In the GT-AC5300 on the QoS page there's no option to do this. Is my unit borked, does that ability not exist in this unit, or has it been moved to some other section? I look under "game boost" and it looks like that old priority system but is it? And if it is why move it and why call it "game boost"? Am I on the right track or is "game boost" some totally different monster? I notice if I enable QoS then enable "game boost", then disable just "game boost" it also disables QoS. What's the deal here? I don't want to "boost games", I've already placed gaming at the top of the list under custom in QoS. I want per device level hierachical QoS prioritization regardless of whether I happen to be "gaming" right now or not. Thanks for any insight.
