Hi, thanks for posting question here.

The QoS (Quality of Service) feature allows you to prioritize the internet traffic of specific devices to guarantee a faster connection when you need it the most. The router has preset an appropriate bandwidth allocation policy, so you don’t need to set different priorities for all devices. Simply set the desired device to High Priority and set how long you want it to remain the high priority, then the device will be allocated with more bandwidth when the network is overloaded.

You may refer to Case 2 in the article to review your settings.
