Nighthawk R7000P- unable to find where to prioritize apps in QoS settings

Hi,

Im finding that my connection when playing a certain online game (iRacing) drops out occasionally when connected to their local servers.

iRacing support has suggested the following changes within my router settings to help combat the drop outs:

Some members fixed this issue by adding in our port range and also changed to UDP only (instead of the default UDP and TCP) on their router settings.

Other members have changed the QoS settings. Delete all those already on the list and put iRacing as the highest priority with ports 15000-52500. Log onto your Router and go to QoS settings. Delete all those already on the list and put iRacing as the highest priority with ports 15000-52500 and UDP only.

The problem is, when i log onto the router and go into QoS settings i cant see an option to perform these tasks?

I can click on the bottom link in QoS settings and change the device priority i.e. my PC to the "highest" priority but not any of the apps?

Could anyone please advise on how to accomplish this? Is it becuase i have the router set on Dynamic Qos perhaps?

Thanks in advance,
