4.3 Advanced 
The third tab window labeled “Advanced” is for Quality of Service. With the proper configuration, the 
limit bandwidth can be took full advantage. QoS requirements are different for various data types such as 
streaming video or music, voice and raw data. To provide higher QoS for streaming data, priority levels 
can be set using tags at the beginning of data frames. Virtual Local Area Network (Vlan) 802.1p priority 
tags on Ethernet frames are used to specify 8 (0~7) levels of “user priority”. Homeplug AV powerline 
allows for 4 levels of Channel Access Priority CAP 0-3). Therefore, the 8 levels of VLAN Ethernet tags 
must be mapped to the 4 levels of CAP priority, where CAP 3 is the highest priority and CAP 0 is the 
lowest. CAP 3 priority might be used for voice and network management frames, CAP 2 is used for 
streaming video while CAP 1 and CAP 0 are used for data. Mapping VLAN tags to CAP levels is easily 
done using the VLAN Priority Mapping function on the QoS tab window.

  Simple Application Mapping: The group allows you to choose what type of traffic with the highest 
user priority you will use your local HomePlug device for by pitching one of the following radios. 
Please select the radio type according to your demand. 
¾
  Advanced Priority Mapping: The group sets VLAN priority to CAP mapping and default priority. 
Note that in HomePlug, CAP 3 is the highest priority while CAP 0 is the lowest priority. The values 
shown in VLAN Tags Priority are the default settings for the first running. 
4.4 System 
The System tab window is for some basic settings of the adapter. On this tab window, you can upgrade 
the firmware to the latest version, reset the adapter’s settings to the factory defaults and configure all 
adapters’ network names.
