Unfortunately, as you can see from the table above, we could not have been more disappointed. Normally, there's a transmitter that is plugged in my router with an ethernet cable and that transmits to the receiver via the electric cables in my house, but from the arrow's direction and all it seems that the receiver is transmitting the signal it gets wirelessly to the other devices, which I think could cause a slow connexion speed since it's far away and probably only picks up 2.4 GHz. Based on our results with the 1200Mbps PA8030 of over 430Mbps, we tested these 2000Mbps adapters with great anticipation, not really knowing what kind of speeds we would get. I downloaded the TP-link utility app and from what I can see, it seems that the transmitter and receiver are switched ( the one marked as 'up' is the one upstairs, which is the receiver that should just extend the wifi coverage). So I got a TP-link powerline wifi extender but it slows down the speed dramatically: on good days, I get 35/20 Mbps and I often get around 20/15 Mbps. However, the router is in the basement and it doesn't reach the second floor (at least in 5 GHz).

So, my wifi network is supposed to be 500/500 Mbps (that's what my provider says) and from the built-in speed tester that is on the management page for my wifi, the speeds are correct.
