How to limit wifi speed to a certain device

As the title say I want to know how. The problem is I live in a small town and my internet provider is called frontier. I already did research on how to and I know about QoS but I couldn't find any video or thread with my router internet provider. The page looks like this I want to ask you if any of you know to limit the speed to a device and what these things mean. If I can limit it to a device.
I know the ip address and mac address of the device I want to limit but the problem is my routers settings in QoS don't look like any others in the videos I've seen.

When I click on QoS in far left column:

When I click on Add Queue at the bottom:

When I click on View/Add Filter Rules:

Someone please help it doesn't seem like it gives an option for a certain device or a mac address.
Thank you
