You might check the thru-put on the powerline link. House wiring isn’t perfect. I use these same powerline devices in my home. For one location where I wanted to put the unit I got less than 1MB/s transfer rate. A movie would start and then quickly the audio would drop and the video would start/stop. Unacceptable. Another location (farther away actually) in the house got excellent speeds and streaming video to that SMP works without issue.
