Lan per powerline does not work. Why?

I have a problem with my Powerline connection.

I would use powerline to gamble in my apartment to avoid random Internet outages. Only the problem is now, in my room I have powerline adapter 540e and a 510e adapter connected to the FritzBox 7520. If I connect the 540e via lan to a laptop or a Ps4, the download does not get as much as it should and when uploading it says that the failed. After this message, the Wi-Fi in the apartment no longer works for around 2 minutes. About 7 months ago in my old house everything worked with other powerline adapters that are now out of date.

Oh yes and the adapters are all plugged into a normal socket.

I'm at a loss and desperate. Please Help.

Ps: I'm not very familiar with this topic, so I may not understand all technical terms.

Could it be that the two are incompatible with each other because they are different models?

ev

No, since it is the Fritzbox set, both are delivered together.

Maybe you have always connected both in 1 phase beforehand. Now on 2 different. Try other sockets in other rooms.

What can also be that another tenant in the house also uses power line and that the signals are now mutually interfering.

Ah ok, that was not clear to me. PLC only works reliably if both adapters are on one phase. L1 or L2 or L3. If they are on different, it will be more difficult unless you use a phase coupler.

Sorry but I don't understand the phases 😅

ev

I'll try that with the sockets, but honestly I would like to understand the phase and I don't yet

ev

And are the phases the reason why the Internet suddenly does not work.

Just imagine that, you don't get the electricity into the house via 1 line, but via 3 different ones. These are then divided so that approximately the same amount of power is consumed on all 3.

In the past, people liked to split two phases into two halves of the room and use the third for lighting.

This means that you may be on 2 different phases. However, these crosstalk, whereby the signal is transmitted from one phase to the other. However, this is much more inefficient than if you transfer the data on the same phase, since crosstalk is usually an unwanted process. Hope you understand what i mean

ev

Ah ok. Good explanation. So far I understand that is now the question of what I can do to fix something.

There are three power lines in the house, which is important for three-phase alternating current, but should not be an issue. In short, a thick cable comes from the ground into your fuse box. Then there are three main fuses on three phases (there's tension on it). So that in the event of a fuse failure due to a short circuit, the entire house is without power. As a result, these adapters can only communicate with each other very badly if they are in different phases. You can find out whether the two sockets that are used for this are in the same phase by unscrewing one of the three main fuses. If both power sockets are off - well, if not then they are different. Main fuses are i. D. R. Labeled with L1 to L3 and not these click things but screwed round things.

So if separated, you can use a coupler to ensure that these high frequencies between L1 and L3 used by the adapters are "let through", which otherwise goes very badly over the zero point.

Alternatively, you could simply switch both circuits in the control box - i.e. Switch both sockets to a common phase.
