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.
