Quick look at the Sineoji PL500EP 500Mbps Mini HomePlug AV with Pass Through.
This is the speed test result with my Macbook Pro connected to the ONT direct. I’m on M1’s 200Mbps fibre broadband plan, so the result looks legitimate.
This is the result with Sineoji on the same breaker. The 2 Sineoji were plugged side by side with nothing plugged to the pass-through socket on the HomePlug.
And I tested on a different breaker, i.e. move 1 HomePlug into my room. The results are more or less the same as the above. I lost about 70% of my subscribe bandwidth when I go through the HomePlug. I must state that the results are not conclusive, although I did the side by side test. I still can’t tell whether the low speed is caused by my electrical wiring or the Sineoji. Shall update again when I get another pair of HomePlug to try.
On a side note, M1 Fibre Broadband rocks! :)
