Hi  @GMB7886,

Do you mean that the router's QoS settings will automatically recover? Or does the settings remain unchanged, but the client can get speeds beyond the bandwidth limit?

1. Please configure the QoS and bandwidth control settings carefully. Sometimes, specific settings may conflict.

2. Make sure you have not reached any device or bandwidth limits set in the QoS configuration.

3. Check if your device has the random Mac address function turned on. Please turn it off first.

4. If the problem still exists, it is recommended that you reset the router.
