Why can I not get speeds of 400 mbps? I can get it hardwired to modem. When I try through netgear router I can only get 200 mbps. Tried a reset after version update. Still only 200 mbps. Help would be much appreciated. Thanks.
I have the AC1750 Smart wifi router. Mosel R6400. It is supposed to handle 450 mbps on 2.4 ghz and 1300 mbps on 5ghz speeds through wifi. It has five ports 10/100/1000 mbps. It is supposed to have auto sensing technology. Through modem I get 400 mbps. After it foes through router only about close 200 through the ports on the router.

Yes.
Turn it off. QoS just gets in the way when you have an Internet speed much over 200 Mbps. It uses processor power.
Remember, you won't get 450 Mbps on 2.4 Ghz or 1300 Mbps on 5 Ghz through wifi.
Those are technical specifications for connection speeds and the like. Real wifi speeds depend on the wifi clients you use and are likely to be a whole load slower than those numbers. If you think about it, how could it deliver wifi speeds of 450 or 1300 Mbps when your Internet has a top speed of 400 Mbps? And 1300 Mbps is beyond the 1000 Mbps of your wired WAN and LAN connections.
I am talking through my ports that I'm hardwired to. I can't get 400 mbps through the ports. Not wifi. I understand about the wifi. I am looking to get better speed though the ports. I have 400 mbps going out of modem. When it passes through router to my other hardwired devices. It is like the router capped it at around 180 mbps.
The modem is from spectrum. I have tested it using my Xbox series one. Directly from the modem and then hardwired from router. The speeds drop from the router. I only said the wifi speeds, because the other person wanted to know the model. Thus I kinda gave it has part has the description.
I don't really know what brand it is. It just says spectrum on it. It was exchanged. Before this one I had an Arris modem from spectrum. This has happened with both modems. I think it has to do something with the router itself. Don't know if a old firmware update affected it or a setting. I don't know off a setting that would throttle how fast data runs through a port.
During the reinstall, make sure to leave qos, access control, traffic monitoring, and parental controls all disabled.
reason why is those services disable cut through forwarding (ctf). Ctf is needed for those older/base model devices to hit gigabit speeds. When ctf is disabled, the processor has to do traffic inspection and it doesn't have the cpu to manage much past that 200mbps.
Usually you can just disable those services and ctf gets re-enabled. But i have seen instances where it doesn't and a full factory reset is needed to re-enable it.
Did you do a fresh install? By fresh I mean making sure not to use a backup configuration. Test if with everything in the default settings and see what speeds you get. If you get full speeds, then start customizing/testing and see at what point it drops the speeds
