Hi
I have a serious problem with Qos in TP-Link AX1800 Wi-Fi 6 Router. Please help me if possible....
I have implemented Qos setting to set priority for Devices.

 

As you see in the Screenshot "CC_Prince" is in the "Low Priority" list and "CC_Lovkesh" is in the "High Priority" List.
But its not working Indeed and both the devices can download and upload at the same speed.
Furthermore the QoS priority of the packets are also same (i.e. Best Effort) for both the devices. PCAP file and RouterConfigFile are attached.
Where did I go wrong?

Your router should have speed limit and filter option in client list - try this guide.

In my testing of QoS, it appears to do some good when the network is under some heavy load and not when it is not. Since my network is not under heavy load very often, I do not use it as it is just more router computing power wasted.

I have also tried speed limiter (See attached screenshot).

 

The issue is that before or after prioritizing the device, the priority of the RTP packets always remained same i.e. BestEffort(0). However, after prioritizing the device, the another types of traffic (other than RTP) having Background(1), ExcellentEffort(3), Voice(6) priorities.

 

Kindly help here.

I proposed a speed limit feature because I thought that you just need to restrict a particular device traffic.

If it's about the QoS packet priorities you'd better contact your local support for additional details.

I have captured a PCAP file and analyzed the RTP stream in both Wireshark and OmniPeek. The priority of all the RTP packets is the same (Best Effort) across all devices, regardless of whether QoS has been implemented.

 

Any assistance regarding this matter would be greatly appreciated.
