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.
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.

Oh so true. That's what FURRYe38 said in the first reply to this conversation.
These days most people, including Netgear, recommend disabling QoS at Internet speeds above 300 Mbps.
Features that use processor power can do more harm than good. That's why, "turn it off" is pretty well the first suggestion when someone has genuine speed problems rather than misunderstanding what speed measurements mean.

Thanks! I was never able to get more than 200 Mbps from computers even when I had 1 Gbps ISP connection. I even downgraded the ISP package: didn't want ISP to come and look on the issue during the pandemic.
So, today I have a 300 Mbps plan. Lo and behold, disabling Dynamic QoS solved the issue! My computer speed went up from 200 Mbps to 300/300 immediately. Wow!
- Kitsap Dynamic QoS has never been enabled. It's disabled now and has always been disabled. With it disabled I'm not getting the full speed.
Glad you got it working. Please mark your thread as solved so others will know. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
