Hello
I'm happy to be a Bouygues fiber subscriber since last Friday. Everything was working perfectly until this morning. Let me quickly explain my setup before describing the problem encountered.
The house is equipped with wall RJ45 sockets (6 in total: 4 bedrooms, kitchen, living room)
Fiber/Ethernet relay + Bouygues box router installed at the telecom arrival point (near the DTI box).
RJ45 output from the box to the patch panel of the multimedia cabinet distributing to my rooms via RJ45. For now, only the living room socket is powered by the box since there's no need for RJ45 elsewhere. I used the TV4K output of my box to provide internet to the wall socket in the living room. I plugged an 8-port Ethernet switch into this wall socket, to which I connected my needs: Bouygues TV decoder, PC tower, PS4, TV, and Seagate network hard drive.
Everything was working well over the weekend, but this morning I had a bad surprise when I turned on the TV with the Bouygues decoder—there wasn't enough bandwidth to receive TV over the internet. After several restarts of the devices and various tests, I concluded that the network cable between the switch and the computer was the source of my problem. When I unplug it, everything works; when I leave it plugged in with the computer on, everything works as well. The problem arises with this cable plugged in when the PC is not on (not using the network through this cable, but still causing issues).
The strangest part is that since Friday I've had the setup where everything was plugged in, the PC not always on, but everything was working perfectly.
What could be the reason for this malfunction?
I've tried with 3 or 4 different cables between the PC and the switch, but the issue always comes back (cat 6, 5e cables...)
Regards

Having read you, I can only conclude that you're getting your wires crossed in your manipulations.

Hi,
is your PC connected via Wi-Fi in addition to this network cable?
Also,
when you turn off the PC, does the port on the switch it is connected to stay lit?
-
@carol103 no no everything is clear in my head hehe!
I'm thinking though that my ethernet connection is plugged into port 8 of the switch, the TV into port 1, and the PC into port 3 or 4. Could the fact that it is turned off cause a "blockage," similar to a traffic jam on the switch?
@brupala no my PC is not connected to the network via wifi, only via ethernet. When it is turned off, the corresponding ethernet port remains solid green. -
Yes, I tested on different ports without success. I will try tonight to reverse it by connecting the Ethernet input to port number 1, the TV to port 2, and so on, ending with the one for the PC.

After various tests, here are the conclusions:
- Port inversion (incoming on 1, outputs on others, PC last), no change
- Turning off the PC using the 0/1 switch located behind the power supply: conclusive, the connection works perfectly. It seems that it's the PC turned off from the start menu that is causing the system to malfunction, but I don't see why... Maybe leaving it in sleep mode instead of turning it off would solve the issue; I haven't tried it yet.
Would replacing the network card resolve this issue?
