It may sound silly, but ALWAYS if I go to a particular Minecraft server (all others work), then the connection via LAN cable breaks off every few seconds for several seconds (red cross appears next to the Ethernet sign). And that is really ONLY ON the server ONLY and ALWAYS on the server. That makes no sense. I'm so helpless…
And via WLAN is it?

Okay, I fell for it.
Wait, what did you fall for now? XD
You just wrote the message so I click on the notification or not?
No, I've written the message to get a message myself, as soon as there's news, because I'm very interested in the topic of the question, but I have nothing to suggest for the time being, as to test it over Wi-Fi, which you already wrote!
Okay ^^
A tip: you can click on the top of the question: "Follow question"
Then you will also be notified.
Now. Of course that would have been easier xD Thanks for the tip!
Let's take a few basic things:
Which router is used?
How is your PC connected? (LAN directly to the router, switches in between, PowerLAN etc.)
Have you already other access types, for example. WLAN tested?
Which network card do you use (in the case of an internal: which motherboard?)
Which Minecraft server is the problem?
Do you have something on your firewall? Changed?
Which operating system do you use?
Do you have any other problems, even if there's no obvious connection to this, with your internet, router or computer?
Do you have any anti-virus programs or similar? Installed?
