Powerline properly wired?

The router is on the ground floor and I have my room in the basement.

Because the connection was not so good and stable, I now try to use Powerline adapters. I know that you shouldn't put the adapters in multiple sockets because it can be easily disturbed. The problem is I have a Ps4 and if I plug the adapter directly into the socket then the USB cable from the adapter is not enough to the Ps4 because the way is 2 meters away. Now I thought I could build one before the whole other devices (the multiple socket) before inserting the adapter there because it is not disturbed by the other devices. Now, however, I was unable to establish a connection at all? Does anyone know why?

Here again a picture of the two multiple sockets for illustration and the situation of the socket to the multiple sockets

(The 6-way power strip ends in the 3-way)

NO you have not read the instructions.

The Powerline must always be plugged directly into the socket and not into a multiple plug.

It works that way, but the transfer rate is so much worse.

Ok thanks, how do I do that with the Lan cable to the Ps4? Should I rather gamble with Wi-Fi?

You know that for Powerline multiple sockets are suboptimal then do you top that by plugging a multiple socket where the Powerline part is inserted into another multiple socket?

Buy a sufficiently long USB cable instead of tinkering with such a construct.

Ok thanks, I thought it was worth trying.

It doesn't make much difference whether you put the part in a multiple socket or not. If Powerline runs bad, it is because of your power supply and the other devices that are so attached to you.

Lan cable can be several hundred meters long. So why no longer buying?

A little hint! How you put it together with multiple power strips is fire-dangerous!

Powerline belongs in the wall socket.

Do it the other way around:

Socket → First power strip → Only Powerline adapter in it → Plug the other power strip into the socket in the Powerline adapter → Plug the rest into this other power strip.

Or better put the Poweline adapter in the wall and a longer Ethernet cable. Before doing so, make sure that Powerline works properly there.

No, the danger was not only a fire risk, but originally in the form of protection against accidental contact, but an FI switch also eliminates this problem.

Either via Wi-Fi or you can get an extension cable (with only one plug)
