Not so this 500.
The transmission rate is very satisfactory, and corresponds to a net 100Mbit cable (in accordance with the connections to the unit) Gross stable values over 200Mbit in transmit and receive direction are displayed here in a 125 m² apartment.
Practically the heist, I can look without disturbing HD TV, better than a 300 MBit WLAN connection (gross), and besides still hang with 2 computers in the network.
Important to me were the integrated sockets because these minimize the interference caused by connected devices.
One should not expect miracles, the best is still a Cat 6 cable, but wireless is susceptible to interference, so I would for critical things when no cabling is possible, favor this kit.
The technology has come of age.
