I'm looking at buying an Archer A7, and was looking at the QoS settings. Let's say I set a device as low priority, 10% bandwidth. During the day, other devices are using bandwith, so that one gets at most 10% (exactly 10%?). At night, when other devices aren't using bandwidth, is the low priority one still restricted to 10% of maximum bandwidth, even though the other 90% is available/not used, or can it use 100% as long as nothing else is consuming any?
