Because I want to allow my qnap all the bandwidth when nothing else needs it but then throttle it as soon as something else so I knew I needed some sort of priority que for my traffic. (The amplifi hd has it but only for WiFi devices not wired).
So I started searching google for how to do that. That led me to QoS topics which lead me to SQM which lead me to bufferbloat which led me to dslreports. I then ran a dslreport on our fastest wired desktop and got a D rating for bufferbloat. Leading me to believe I have a bufferbloat issue.
So not being a network guru, it was really just weeks of online reading and then seeing the dslreport D rating. I could be totally wrong.
It sounds so simple it really just want to prioritize my traffic by IP or MAC address. QNAP low priority, SmartHome stuff high priority, everything else normal. The rabbit hole researching it took me down was never ending
