Dynamic QoS Decreasing Speed
I recently increased my speed from 200 mbps to 400 mbps through my ISP. Since then my router will get the full 400 mbps speed through Wi-Fi but none of my devices that are connected to the router via...
I'm still not getting full speed when connected via ethernet. I've tried all the suggestions from this thread and nothing seems to resolve the issue. I reset the router for a 3rd time and it didn't make a difference and I followed the instructions from this thread.
I’ve rest the router twice since I’ve upgraded my internet. The first didn’t help. The second time the router worked great for 3 days and then it after day 3 the devices connected via Ethernet started only getting about 250 mbps instead of the 400 mbps.

Always helps to have full details. Anything else you haven't told us about?
For example, earlier you said:
"Since then my router will get the full 400 mbps speed through Wi-Fi but none of my devices that are connected to the router via Ethernet will get that speed, they will only get around 250 mbps."
That is highly unlikely and doesn't make much sense, given the usual overhead for wifi connections. It raises questions about how you are testing these speeds.
This is also suspicious:
"The only way I will get the 400 mbps speed is if I press “Apply” in the Dynamic QoS screen on routerlogin.net."
Same question. Where do you see this 400 Mbps? Sounds more like an "on-board" speed test, never a reliable indicator.
michaelkenward Sorry I missed some details, I've tried a lot of things and it's hard to keep track of all of them.
I've tested the speed on multiple devices both wirelessly and wired. I've tried different ethernet cables and the results are the same. Wi-Fi consistently get 400 mbps or more using speedtest.net. When I test a wired connection using the same device, it test around 250 mbps. When I connect the same device directly to the modem, I get the full 400 mbps or more. Then when I reconnect to the router via ethernet I get around 250 mbps again.
The only way I get 400 mbps on a wired device is by pressing "Apply" in the dynamic QoS setting. I don't change a single setting, only press "Apply" and wait for the settings to update although I didn't change anything.
I have attached some screenshots to show proof. The 289 mbps is before I pressed "Apply", the 400 mbps is after I pressed apply.
Anyone else have any other suggestions?
Remember, you asked.
Shut off Dynamic QOS and leave it off. If you have a 400 Mbps capacity connection you have no need for QOS. QOS disables cut through forwarding (CTF) and uses up clock cycles (processing power) from your router that can better be used elsewhere.
You are jumping through hoops based on faulty information (on board tests). Install the native operating system test applications from Ookla for testing on your devices.
Some lessons are harder to learn than others. Keep at it.
