Qos broken on new to link WiFi 7 router
I am from India. I recently bought an archer GE400 US. The internet is working fine but having ping issues during download and upload on the network. I have fiber internet with 150 mb upload and download. I configured the QoS bandwidth to every value: 100,110,135.150 but no change in bufferbloat latency. So I am forced to use it as my secondary router with QoS enabled on my primary mercusys mr70x router. Please help.

Hello @SamuDas ,
Welcome to our community.
Have you tested the latency values, bufferbloat, etc., with QoS enabled and disabled respectively? If you can, please send the screenshots with test results here.
So your network topology now is ISP modem—MR70X—GE400)))((( client devices
(Note: — stands for wired connection,)))((( stands for wireless connection )
Please tell me how many clients do you have and what are they?
The QoS function of the MR70X doesn't cause any latency, right?
Please try to change DNS on the router as below:How to Change the DNS servers on the wireless router
Also, please confirm all clients and routers are up to date.

Hey man DNS did not help I got my fiber terminated into ont and there router connected to ont through ethernet.

@SamuDas ,
Have you compared the latency of the GE400 when it's used as the main router with QoS enabled and disabled? What were the test results?

@Joseph-TP Yep with mercusys mr70x as main router and qos enabled on it it works wonders even connected ge400 as secondary it had no bufferbloat but with disabling qos on my mercusys router the problem arises. Even after enabling the qos setting on ge400 after connecting the lan cable from mr70x to wan port of ge400 bufferbloat remains unfixed but bandwidth is reduced based on limit I set in qos settings.

Hello @SamuDas ,
Thanks for getting back to us.
First, from a cost-performance perspective, if your network speed is only 150Mbps, you can consider a standard WiFi 6 router that supports gigabit ports.
So, you tested the following scenarios:
1. MR70X (QoS Enabled) + GE400, no bufferbloat and high ping
2. MR70X (QoS Disabled) + GE400, has bufferbloat and high ping
3. MR70X + GE400 (QoS Enabled), has bufferbloat and high ping
4. GE400 (QoS Enabled) + MR70X, has bufferbloat and high ping
In summary, if the MR70X is used as the main router and QoS features are enabled, bufferbloat and high ping will not occur, right?

@Joseph-TP
Yes you are absolutely right.

Hi @SamuDas ,
If so, this shouldn't be directly related to enabling QoS.
Please temporarily remove the MR70X and then test with QoS enabled and disabled, respectively. Will the GE400 network still experience latency and bufferbloat?
To help you efficiently, I've forwarded your case to the TP-Link support engineers, who will reach out to you using your registered email address later. Please keep an eye on your email inbox for follow-up.

@SamuDas Configuring QoS bandwidth to be greater than 150Mbps or disabling flow control function may be helpful. You can try.
