Slow powerline backhaul
I have two PX50 units. Upstairs, I have a home server connected to the satellite PX50 via ethernet that can deliver gigabit speeds to a laptop connected over 5GHz wifi. Downstairs, I have a desktop PC connected to the main PX50 via ethernet that has a much slow connection to the home server, at about 300mbits/sec. My two PX50 units are connected via PLC + 2.4GHz + 5GHz. Before I bought the PX50 units, I was able to achieve gigabit speeds from my desktop to my home server using a pair of TP-Link TL-PA4010KIT. Why is the connection between the two PX50 units so slow?
I don't know how to find the the hardware version so I selected V1.
