"Save" with the option enabled applies the QoS settings to all adapters
discovered on the network and authenticated by the Utility.

Save: Click it to save settings to corresponding adapter.

Cancel: When clicked, current settings will not be saved.
Tips
1. The default QoS policy for the device includes 8 ToS rules and 1 IP
multicast rule, which will be deleted if the QoS-Quick Setup functionality is
activated.
2. You can only apply a single option in Quick Setup to an adapter at a time.
When you switch from one option to another, the former will be deactivated
automatically.
3. Activating application/service under QoS-Quick Setup does not remove
existing MAC/IP based QoS entry.
4. There is a limit on the number of configurable QoS entries for each data
type: up to 14 entries respectively for MAC address based data (Eth Source
Address+ Eth Dest Address) and IP address based data (IPv4 Source Address
+ IPv4 Dest address), up to 8 entries for IPv4 Precedence, and 16 entries for
port based data (TCP Source Port + TCP Dest Port + UDP Source Port + UDP
Dest Port). Errors will be reported when configured entries
such entries will not be saved.
5. The QoS feature does not increase your existing bandwidth. It prioritizes
specified data over your existing bandwidth.
6. Advantages of the QoS feature are typically seen on congested networks.
Normally, Powerline network is not confronted with congestion as powerline
transmission rate reaches up to 200M while ADSL Internet connection rate is
only 12M at most and yet shared by multiple users. So, you may not
experience obviously tremendous benefits from your QoS settings if you are
enjoying a smooth network. However the QoS feature does bring you more
or less benefits, they are just not as tremendous as in a congested network.
7. If you set a PC's MAC priority level to "0", IP priority to "2" and enabled
Surfing priority in QoS--Quick Setup section, then adapter will consider the
MAC priority of "0" a currently valid priority for packets received from such
