Hi, thanks for the feedback.

Have you run a speed test on the controller device itself?

After viewing the troubleshooting history with the previous users, it turns out the speed on the device is limited, but the real-time speed rate on the Deco App is still showing a high speed, which might make users think the speed limit is not working as expected:

Wait for your reply.

Best regards.
