Sounds suspiciously like a network loop to me too. This can also occur if a bridge is unintentionally installed between the LAN and WLAN. When I look through your list of network devices, the Philips Hue Bridge catches my eye - maybe start troubleshooting there.
If it isn’t, activate the Spanning Tree Protocol (STP) on the Internet box in expert mode under Network.
Have you tried turning it off and on again?

So, I have a cable that goes into a switch, which in turn goes into another switch (through a cable from the switch) (yes, I know, loss and stupid, but it’s enough) and that in turn could be the error?
You mean something like that?
No, that shouldn’t be the problem. Because I have been using this for several years.
On Switch 1 there is a TV, an XBox, a Nintendo Switch, the UHD 4K player, an Apple TV and a gateway for smart home control. A cable goes from Switch 1 to Switch 2 in the next room.
In addition to the PC, a TV with Netflix is connected to Switch 2. From Switch 2 goes to Switch 3 with a cable
A PC and an Apple TV are connected to Switch 3
If I were to go back from Switch 1, 2 or 3 with a cable to another switch or to the IB 4, then that would be a loop.
An example of a loop (the loop is created by the red cable):
Very good, then it really seems to have been a loop.
However, by activating STP you only circumvented the problem, but didn’t actually fix it. Your entire network traffic may now even run through the Hue Bridge. For stable operation, it is therefore important that you either disconnect the LAN-Anschluss on the Hue Bridge or deactivate its WLAN connection. To test whether the loop is really out, deactivate STP again. Whether you leave STP on permanently is a matter of taste. What is certain is that a home network must run stably even without STP.
PS: What exactly do you mean by “everything turned red”? All your Philips bulbs turned red, or what?

Hi @Sevii
Cool that you found the error. What do you mean by tree protocol?
P.s. If you haven’t had the new Internet box for 14 days, try returning it. Swisscom always says something about a 14-day return policy. Unless the IB3 was newer and you had a different one before, then I would keep the 3.
Another question if I just connect a switch that comes directly from the router. Can I then connect my devices there without any problems? Or do you really need an Ethernet cable back? Apple TV (latest generation), PlayStation 5, Samsung TV and also a Nintendo Switch would then be connected to the switch.

Yes, that’s exactly what a switch is made for. That you can connect multiple devices.
Exactly then you have a loop. 😵
You are not allowed to go back under any circumstances!

Hello, I now only have one switch (I replaced the linked switch with one from TP-Link (from Swisscom’s official website)) and that’s it. Now, after a few MB/S downloads, my PC suddenly experiences a brief internet outage (no internet symbol) and then it works again. I don’t understand it anymore. I can’t even see what it is because the error quickly recurs. It really can’t be the cable, all other devices work. Has the mainboard been fried or is it Windows?

Hello @Sevii
You could try out Linux on your PC with a USB Live and then you’ll immediately see what’s going on with your PC.
I also have sticks like these in the support area, so I can show customers very quickly that the PC is working and that some Windows driver has gone badly wrong.
As long as you only try out live mode, nothing will happen to your data.

Well, apparently it’s not my PC’s fault. I’m having problems again after about a week. This switch doesn’t let any signal through. As soon as I unplug it and plug it back in, it doesn’t work again very shortly afterwards. I also no longer have access to this Swisscom internet box thing. I’m really starting to despair. Is this because of Phillips Hue? Or is the Swisscom network simply too stupid for multiple devices?
Good day everyone.
I also had a post before where I asked for help and I’m happy that there are nice people here who can help you faster and better than Swisscom support could ever do.
I have a question now; Apparently I had a network loop back then because I;
From my INTERNET BOX to a switch to another switch. Then the problem was solved.
Now I bought another switch from Swisscom itself (TP-Link Jetstream) because I thought it was compatible and that it was better.
Well after a week it is no longer recognized by the “system” and is thrown out. Since I have no idea what it could be, I wanted to ask here. Maybe someone has experience.
Important: I can’t get an internet connection on the devices connected to the switch. With the rest, yes. I don’t think it can be the cable because the internet was already coming through before. I haven’t changed or configured anything on the switch. Unpacked, plugged in and ready. It went smoothly. I’ve already tried a restart.
It currently looks like this in the system:
This is what it looks like.
Have you already removed the TP-Link switch from the power supply for 5 seconds?
Is the TP-Link connected to the Internet box at 1Gbit/s Anschluss.
There is another error in that the TP-Link is not displayed in the network diagram when the Internet box is restarted, but it always works in the background for me.
N.B. I also gave the TP-Link switch a fixed IP address in the Internet box menu.
