Bridged Ethernet?

Solved

Hello,

After reading quite a bit here and there, I prefer to summarize here:

As a new fiber subscriber, I am very surprised to see that over Ethernet, all my bandwidth tests show between 95 and 100 Mbps (whereas I was hoping for more)

On wifi, it's very variable (why?), but I've already seen it display up to 295 Mbps.

I updated the Intel Network Drivers today retrieved from the MSI website
(MSI MPG Z390 GAMING EDGE AC motherboard)
network card: Intel I219-V

In Control Panel\Network and Internet\Network Connections
Right click > Status (of the Ethernet connection)
I can see:
Speed: 100.0 Mbps

Regarding the box, I am on the 2.5Gb port (also tested on the 1Gb port) (freebox POP)

Concerning the cables/installation:
fiber > freebox POP > Ethernet cable to wall socket > wall socket in office > Ethernet cable to PC

I have 3 cables (1 cat6 and 2 cat5E), and I therefore tested all 3 possibilities (eliminating one each time).

Additional check:
'Speed and duplex' is set to 'auto negotiation', if I switch to 1Gb, full duplex, the test finishes at less than 10Mbps :(

Note: the tests I’m talking about were done on speedtest.net

I hope I have provided all the necessary information for you to help me.

Thank you in advance to anyone who has an idea/a test/a solution to propose :)
or who might simply tell me that I have a limiting element and that everything is therefore normal (?)

Have a good evening

Hello,

The electrician who did the wiring checked and rewired the sockets. :)

Result: 800Mbps through the wall sockets.

Problem solved, thank you for your support in the diagnosis!

Hi,
is your card connected at 100Mbit/s or not?
What is the model of your ethernet card?
If you can't connect at gigabit speed, you need to switch to another one, that's it.

integrated into the motherboard mentioned in my first post.

in the specifications, we can clearly see:
Throughput per port 1GbE (right?)

That's not the question:
are you connected in gigabit or not, it shows up in the connection properties under Windows...

Hello,

In Ethernet, with a Gigabit card, the connection should indeed be marked as gigabit. Normally, the auto setting remains the best option. Either the card has a problem, or more likely in the connection, there is imperfect wiring. The wiring of the wall sockets, or the patch panel in the central box, which connect the two wall sockets (you haven't detailed this installation). For gigabit, all 8 wires are needed; if one wire is improperly connected, then it switches to 100Mbps.

The best test would be to connect directly via Ethernet with a single cable between the box and the PC.

For WiFi, these are waves that can be disrupted, and often the WiFi transmitter of boxes is not the best (but I don't know precisely about the Freebox Pop, but it was the case for the Revolution and the Mini4K). Then, you also need to consider the WiFi type of the PC, b/g/n/ac, with the latter being the most efficient.

ok, for the sake of science, oh no, to advance the diagnosis, I'm going to try to connect the PC directly to the router ;)

You weren't connected directly, what was between the two?

ah ok,
thank you JP,
I had completely forgotten about that part,
but well,
we have another question pending, but it's true that we had that too:
In Control Panel\Network and Internet\Network Connections
Right click > Status (of the Ethernet connection)
I can see:
Speed: 100.0 Mbits/s

At this point, a faulty wall socket cannot be ruled out, the direct test will tell us more.
Also,
with a faulty gigabit connection, if we force gigabit, well it doesn't connect at all, compared to autoneg.

Good evening,

The latest tests: on a laptop running Linux (more convenient than having to move the tower to the box):
  • same measurements on the wall socket in the office: 94-96 Mbps for both download and upload
  • same measurements on another wall network socket: 94-96 Mbps
  • connected directly to the box :

-> 4 Mbps for download
-> 600 Mbps for upload
I honestly don't understand why the download result is so low?
I'm surprised to see the upload so high...

If you have any ideas/conclusions/other tests, thank you in advance.

Continuing my research, another piece of information:
I just discovered on Freebox OS, the Local Network tab > Switch
  • through the wall sockets, '1000 base T-FD' appears one, two, or three times before stabilizing on '100 base TX-FD'
  • when I plug directly into the box: 1000 base T-FD right away...


(I took the opportunity to test with each of my cables and on all 3 ports)

So I can undoubtedly blame the two wall sockets and the wiring that connects them, right?

Absolutely, yes, that's the right track.
We will need to check and test the wiring of these sockets.
