Hello everyone,
I have a problem.

I replaced my (Germany) Telekom Speedport 4 with a Fiber Modem 2b and connected directly via PPPoE using the ER8411. Everything worked perfectly.

However, since then I can no longer start the Minecraft Launcher, or it freezes and is very slow. The same happens with the Xbox Launcher.
This is now happening on all PCs in the network.

Does anyone know more about this than I do? I’ve basically tried setting everything up, but without success.

Sometimes it also says that I’m not connected to the internet (shown in the launcher), which of course is not true.
