The router class is a marketing trick, indicating the sum of total theoretical maximums in ideal conditions for all supported bands. RT-AX56U is marketed as AX1800 class router, up to 574Mbps on 2.4GHz + up to 1201Mbps on 5GHz = 1778Mbps maximum ever possible connection speeds. Real life situation is much different, usually far from what was advertised. Also, WiFi is half-duplex communication, so divide connection speeds roughly on half and this is what throughput you can get. For example, to push around 400Mbps throughput you'll need minimum 2x2 AC clients connected at maximum 866Mbps link speed (located close to the router). Also, the radio is shared by all connected clients (including the ones connected to AiMesh in dual band routers with wireless backhaul, including the ones connected to repeaters, etc.), so 400Mbps you may get to one single client only, if the others stay quiet. At the moment people with Gigabit ISP have a slim chance to see something closer to Gigabit over WiFi only with 4x4 AC client (1733Mbps link speed) or faster (AX) and only close to the router.
You may not need QoS on a 500Mbps ISP line, especially if the upload is also 500Mbps. Many consumer routers can't do 500Mbps with QoS enabled, not sure what's the situation with RT-AX56U and RT-AX58U, never had one in my hands to test it.
hah spectrum cable might be 400mbit down but upload is pitiful at best its only 25mbit, so QOS will most likely still be need in NJ optimum was 200 down/40 up now i have double down but half the up.
Though I can get AX58Ufrom my best buy or the AX88U but not the AX56U
