Full speed depends on several factors ....

I bought the kit as a successor to the TP-Link 200Mbps, since the latter achieved a very low throughput with me. In principle, the specified speed will of course never be reached, because it is always about the gross throughput. Here the gap between reality and manufacturer information is again enormously. Of the 500Mbps perhaps only 40% of the actual flow rate can be achieved with best conditions and power line quality ....

Added to this is of course the length of the current line of adapter to adapter. With every meter go west Mbps.

In my personal case, I might bridgeable Air Line 5 meters. But are reinforced concrete walls between the 5 meters, I have no way with WLAN and am dependent on Powerlan. For this, the lines seem to take complicated paths here in the apartment. I have, in effect, a flow rate of max 4-5 Mb / sec .....

But for surfing and smaller content, Youtube videos, etc. This ranges all.

I pull from 2 stars because once the advertisement here again too much promises (wohoooo 500Mbps !!!!!) and what most annoys me personally, both adapters have a Spulenfiepen. You can hear it when you are standing in the immediate vicinity. That's already noticed more often in TP-Link products. My TP-Link switch and whimpers, the 200Mbps adapters also squeaked one of two .....
