This Quality of Service (QoS) Engine will allow you to prioritize particular
clients over others, so that those clients receive higher bandwidth. For
example, if one client is streaming a movie and another is downloading a
non-urgent le, you might wish to assign the former device a higher priority
than the latter so that the movie streaming is not disrupted by the trac of
the other devices on the network.

Under Connected Clients, you will see device cards representing each
connected client. If some are o-screen, you can use the < and > buttons to
scroll through the cards.

A maximum of one device can be assigned Highest priority.

A maximum of two devices can be assigned High priority.

A maximum of eight devices can be assigned Medium priority.

If no devices are explicitly assigned a priority, they will all be treated with
equal priority. If some devices are not assigned a priority and others are, the
unassigned devices will be treated with the lowest priority.

To assign a priority level to a device, drag the device card from the All
Devices list over an empty slot and release the mouse button. The card will
remain in the slot. If you want to remove a priority assignment from a device
and return it to the All Devices list, click the cross icon in the top right of the
