It is possible to connect powerlines with different data rates and brands as our devices use the HomePlug AV standard which makes any device compatible no matter the brand or data rates. For instance, you can connect a powerline 600 with a powerline 500 as they have similar data rates. That is why, we strongly recommend not to connect a powerline 600 with powerline 1000 or more as the data rate will be limited to the maximum speed of the powerline 600. In addition, a Powerline 600 can be connected to powerlines 600 of different make but we cannot guarantee that it will work properly with powerlines 600 from other make, as there may be software differences
