Chapter 4 The Configuration Utility
messages FROM your powerline adapter are sent in your powerline network. Transmissions TO your
powerline adapter do not receive any priority.
For example, if you have a file server on your home network to deliver music and movie files to
computers in your home, you should set the priority of the powerline adapter connected to this
server to Medium. If video traffic is delivered too slowly, quality problems may occur.
On the other hand, a powerline adapter attached to a printer should have a low priority setting
since the slow delivery of messages will not affect the print job.
Similarly, if you want to prioritize any downloads from the Internet, set the priority on the powerline
adapter attached to your Internet gateway to High.
Allocate priority settings based on application type as follows.
Table 5 Priority Settings
PRIORITY LEVEL
High
Medium
Normal
Low
The figure below shows an example powerline home network connected to the Internet.
• Device A is a printer and does not handle traffic with high importance, so the powerline adapter
connected to it can be set to low priority.
• Device B is a file server, delivering audio or movie files to other users on the network. The
powerline adapter attached to it should have a medium setting.
• Device C, a home computer which connects to the Internet, can receive a normal priority setting
as it usually sends simple requests for data. For example, when you surf the Internet, your
computer sends requests to open web pages.
• Device D is a modem attached to the Internet. It should receive a high priority setting if you want
faster downloading through your network.
