Wall Ethernet socket not working with computer

Solved

Hello everyone,

Having wall RJ45 sockets in my home, I decided to install a switch in my communication cabinet to make the internet connection available via cable in all the RJ45 sockets throughout the apartment.

After ensuring that all the sockets were working properly, I connected my desktop computer via Ethernet to the socket in my bedroom, but I have no internet. The socket works, as when I connect an Orange UHD TV decoder, it functions properly.

I am therefore reaching out for your help to find out why it is not working.

To clarify: my Ethernet cable works, the Ethernet port on my computer does as well, and I’m using a basic TP-LINK switch, which is sufficient for my needs.

It's also important to note: when my computer is connected to the Ethernet socket in my bedroom, the light on the port of the switch occasionally blinks.

Thank you in advance!

For wired networks, a tester is almost essential..
Just one poorly connected wire and goodbye to 1000 Mbps..!

You can find testers for less than €5 on Asian mail-order websites.

I would also like to point out that the cables in my home are Grade 1

If the grade 1 in question is PTT298, it allows for gigabit ethernet when it's wired correctly.

Hello,

This could be a wiring issue with the wall socket, or a partially faulty patch panel, a bad contact, or a short between several wires. You would need to dismantle the sockets to check.

You should also test this desktop computer on another wall socket to confirm that it’s not the cause of the malfunction.

Thank you for your response. I have reconnected each of the outlets in the apartment, and I have also tested other outlets that I can confirm are working properly, but nothing changes; the same problem persists.

Hello,

I didn't understand one thing:

Does the PC work in the same way on all the other sockets?

And directly on the box?

Also,

you say you don't have internet, but does it indicate connected?

Can you paste the result of ipconfig/all when you are on this socket?

see output file

In any case, try another cable anyway.

And there you go, there you go ....

But misery, how annoying the line spacing is!!

The PC does not work on any wall socket, works directly on the box, or even via a Wi-Fi repeater equipped with Ethernet ports. When I plug into a wall socket, my computer shows "not connected".

Here is my ipconfig/all:

Windows IP Configuration

Host Name: DESKTOP-ANSHG61

Primary DNS Suffix:

Node Type: Hybrid

IP Routing Enabled: No

WINS Proxy Enabled: No

UPDATE: Problem solved!

It was my ethernet cable that was at fault. However, having a PTT298 cable, I realized that I am limited to a speed of 100 Mbps. A bit unfortunate having Orange fiber...

No, the PTT298 allows for gigabit; many people use it that way, up to a reasonable distance (let's say 30/40 m) it works.

It’s certainly some other issue if you are limited to 100.

Are the other sockets at 1000?

What is the switch?

All connections are at 100, however when I run a speed test by plugging the computer directly into the switch in the communication box I get 266 Mbps download and 406 Mbps upload. The switch is a TP-LINK TL-SG105.

Is the switch indeed gigabit, is it connected to the box? And during the speed test, is the PC's network card in gigabit?

If the PC is in gigabit on the switch and is in 100mbps on all the wall sockets, it means the wiring of the wall sockets and/or the patch panel wiring is not good. If you could provide us with photos of these open sockets.

The switch is properly connected to the box via a wall Ethernet socket located in the living room.

The PC's network card is gigabit.

Unfortunately, I am not on site, but I followed this connection EXACTLY on all the Ethernet sockets:

(Note: the box is located in the living room and connected to one of its Ethernet ports on the wall outlet in the living room)
