The following problem: In the room I had previously a Dlan 500 Duo, which was connected to the PS4. In the speed tests at the ps4 I had mostly 20mbit. Now I changed the Dlan on another model, the Dlan 200 av plus, same cable, same slots. However, I have according to the speed test only 3.5 - 4mbit s.der PS4. What is it?
