Limited Ethernet Connection, Unidentified Network
SolvedHello,
After testing everything indicated on this page (https://www.commentcamarche.net/maison/reseau-wifi/1075-resoudre-les-problemes-de-configuration-ip/) and searching for solutions without anything working, I'm starting to despair and I'm reaching out to you.
I'm currently with SFR, connected to fiber. The fiber box is connected to the electrical panel (see photo) and I have several RJ45 sockets in each room. The idea is to connect my desktop PC, which is in a bedroom, via an Ethernet cable connected to the dedicated RJ45 socket in that same room.
Here are my devices:
My box is connected to the RJ45 socket in the living room directly. I then have a switch that is connected with an Ethernet cable to it to return to the electrical panel.
On this switch, I have another switch to which I connected the fiber box with an Ethernet cable and then I redistributed the connection from the switch to the living room and the bedroom where the desktop PC is located, all obviously with Ethernet cables.
The installation works except for the connection of the desktop PC to the Ethernet network which indicates the following information:
To check that it is not the Ethernet card of the PC, I connected a laptop, same result. I also tried connecting the laptop to other Ethernet sockets and that doesn't work either...
However, when connecting the laptop directly to the box or the switch it is connected to, there are no issues, the Ethernet connection works.
Is there a problem with my Ethernet connections or a manipulation to do on my desktop PC? Knowing that all the outputs of the switches light up green, I deduce that the connections are presumably established.
Thank you in advance for your help in getting this thorn out of my side :)

Hello,
The switch behind the fiber connection allows the box to receive the internet connection, but this connection is not redirected from the box, to the switch, and then from the switch to the desktop PC.
If there are not 2 Ethernet wall sockets in the living room, the switch should be removed from the central unit and the box should be installed there, which will directly power the TV box in the living room and the desktop PC in the bedroom.

I then have a switch connected with an ethernet cable to it to make the return to the electrical panel.
Does this mean 2 wall sockets in the living room? If so, there needs to be a cable going out from the patch panel socket; there are currently 2, but we need 3. Connect the patch socket directly to the box with the output from the fiber box (without going through the switch), and then connect the return socket from the living room to the switch so that the desktop PC will be properly connected to the local network.

Hello,
we agree that it's the ONT we see next to the Netgear switch?
As mentioned before, the ONT should not be connected to the switch (unless it was a manageable switch with two VLANs), but directly to the patch panel going to the box.
But the best would be to connect your box to the patch panel; you wouldn't even need this GS305 here, you could place it in the living room instead.
Something like this:
And there you go ....
But goodness, how annoying those line spaces are !! -
Thank you very much for your feedback :)
I confirm that it is indeed the ONT next to the Netgear switch. And unfortunately, I only have one RJ45 socket in the living room.
Originally, I would have liked to install the box next to the electrical panel, but the problem is that there is absolutely no room to accommodate it, so closing the door of the enclosure is not possible… And I really don't want to leave the box lying on the floor in the hallway with cables hanging down.
That's why SFR suggested going for a solution with an ONT, except that according to the technician who came, it was enough to add switches. He didn't mention the necessity of having two wall sockets in the living room at all...
To summarize, and if I understood correctly, it is not possible at all to get the ethernet to work in the bedroom in this configuration, unless I connect the box directly to the electrical panel?
And if I don't want to apply this solution, I either connect to the Wi-Fi on the desktop PC or I buy a long ethernet cable that I plug in and unplug directly from the box in the living room, is that right?
Thanks again for your feedback :)

In fact,
with two manageable switches, one in the cabinet and one in the living room, it would be feasible to have a single socket in the living room and by configuring different VLANs on it.
The problem is that the boxes have several poorly documented VLANs on the WAN port: generally one for the internet and others for video streams, you can search on lafibreinfo, there are plenty of enthusiasts tinkering with things like that.
Another possibility: install a fiber patch cord to relocate the fiber connection to the living room.

Thank you for your solutions, brupala, but I think it exceeds my skills a bit and being a tenant, I'm not sure the landlord would be too thrilled about drilling holes in the walls for the installation of a fiber tie ^^
Unfortunately, I think I'll have to settle for using Wi-Fi on the desktop for regular use and plug in a long Ethernet cable when I need a bit more "power".

You also have mesh Wi-Fi solutions, which are more expensive but work well even for connecting machines via Ethernet.
Or a shelf under the panel to place the box; I wonder why SFR provides such a large ONT, as they are usually much smaller than the box, or even integrated into it (box 8).
Also,
Often, the boxes come with a wall mount to hang them on the wall.

@brupala
Well spotted on the mesh wifi, I hadn't thought of that! If I understood correctly, your idea would be to connect the main router to the box and then install the satellite in the bedroom, connecting the PC with an Ethernet cable to the latter?
As for the OST, that's not really the issue since its size allows it to fit in the electrical panel, unlike the box which is way too big (also box 8).
As for the wall installation, it would look really ugly and the door of the electrical box wouldn't close anymore, so I’d rather avoid that ^^

The TV decoder must be able to connect via wifi, and it does not require a high speed; you could put the box in the bedroom with the desktop computer.

Here is a picture of the back of the TV decoder, it doesn't look like it takes Wi-Fi...
On the other hand, it's not a bad idea to install the box in the bedroom, I hadn't even thought of that!
If I go with this solution, would connecting the TV decoder directly to the RJ45 socket in the living room and then connecting it to a switch at the electrical panel work? Or will I face the same problem as now but this time in the other direction by not having network on the box?

For the wifi, there is no port, that's the principle of wireless ;-)
You need to check the settings of the TV box.
The TV box on the wall socket has exactly the same initial problem as for the desktop PC. For the network, they are just 2 devices with wired Ethernet connection.
I don't know the SFR equipment, but don't they provide powerline adapters? That also allows you to connect a device through the electrical network, ideally the TV box, which, as mentioned for the wifi, is not demanding in terms of network bandwidth. -

Yes, good point ^^ I thought there would definitely be a Wi-Fi logo somewhere to indicate it.
I checked the settings of the TV box and apparently Wi-Fi connection is possible :)
I think I'm going to test this solution with the box directly installed in the bedroom!
As for the connection of the TV box, do you think it will be more effective with powerline adapters or Wi-Fi? Considering that there is a certain distance from the living room to the bedroom (more than ten meters), I could install a mesh Wi-Fi setup as suggested by brupala, right?

For the TV connection, it seems that DTT is no longer really part of the plans for future access to TV...
