Hi, It is suggested to choose your powerline adapters based on the following rules:

1. G.hn powerline devices are not compatible with HomePlugAV powerline devices, for example, devices like PGxxxx cannot work with TL-PAxxxx.
2. We strongly recommend using the same serious of powerline devices in one circuit/network, for example, if you already own a set of TP-WPA8631P KIT, it would be better to add TL-(W)PA8xxx devices as well. Using different series of powerline devices in one network might result in performance degradation.
3. We do not recommend using TP-Link powerline devices with other brands in one circuit/network, there might be some serious compatibility problems.

For more details, please refer to  Are the TP-Link powerline adapters compatible with each other?
