Hi

Currently, Deco does not support limiting the bandwidth of specific clients.

Thank you for posting on the TP-Link community, and we certainly appreciate all your feedback and feature request(s) here.

While we don't have any specific details that I can share around if this feature can come to all the Decos, or when it might, I'll make sure to log this feature request and pass it along to the team.

I'm moving this conversation into the ‘Feature Request (Decos)' area and tagging it as a ‘Future Consideration’ for better visibility.

Feel free to let us know of any other feature requests you may have, we’d be happy to send them up for you.

What is the main purpose of the QOS function?

When I set one to high priority.
the other devices are limited in speed.

Hi

We noticed you set the bandwidth to 7mbps, which means the device's speed would be limited.
Why do you wish to enable QoS+high priority or restrict everyone's uploads and downloads to 10mb? What needs are you hoping to meet?

Warm regards.

  @約瑟夫-TP 

I'm going to use it for the meeting. 
There's 20 people in the meeting, so we need to limit it to between 7 and 10 mb per person. 
Because we're using 4G LTE.

Hi

Currently, Deco X50-4G does not support setting bandwidth limits for each client, even through QoS. Currently supported models are only Deco X50/X55_v1.

However, I will feedback your needs to the relevant departments for evaluation.
Warm regards.
