Hey, so a little bit of backstory for you to understand my frustration with this situation

Built a PC for my gf at my place everything works fine bla bla bla then one day BOOM the integrated ethernet thingy doesn't work and doesn't appear on the BIOS tried literally EVERYTHING and got an external card that i plugged in, worked for a bit then it kept disconnecting whenever we were playing games, again tried literally EVERYTHING nothing work and it kept disconnecting over and over and OVER

So where are we at now, i bought another motherboard which is the aorus b450 pro version, drivers that came on the CD are installed, tried different ethernet drivers NOTHING works and it keeps disconnecting from time to time which is simply impossible for me only to solve no matter how hard i try

Here's the ipconfig /all if you can take out something from it i'm desesperate, i'm sorry it's in french hope you understand enough

Is the PC you built for your gf at her place or your place?

Have you tried swapping in another known working Ethernet cable on her computer? Any wall jacks, switches, etc. leading back to the router?

On her computer look in Reliability History for any network related error codes, warnings, or informational events.

Network

Make and model: Modem, Router, or Modem/Router if combined?

The router's logs (if available and enabled) may provide some clue about what is happening.

Who has full admin rights to the router? You will need help from that person.

One of the first things to try would be a different cable, different jack.

Do you have a lot of devices connecting to the network? IE are you sure there are enough allocated addresses by what is performing DHCP?

Hi and thanks for the fast answer, the PC is at my place, i tried different cables and to put it in the wall jack where i'm plugged in it didn't do a thing, i don't think the router is the problem as she's the only one having that issue with ethernet

Tried to look in the history and nothing really stood out regarding the connection

Router logs are completely off topic and by that i mean they don't tell me anthing about what's happening to internet

I should have the full admin so there won't be no problem

One of the first things to try would be a different cable, different jack.

We have 3 in total which never caused any issues before this, how can I check that?

I would try booting a linux live cd/usb and see if that works correctly. If so, you never had a hardware issue to begin with and it's a windows issue. If it doesn't work, it could be hardware again, or the network.
I had hardware issues, i changed the motherboard and it's still going on

So I don't think that's right as the chances of 2x hardware failures like that is not very high. Hence the live cd/usb will help make sure.
I agree with you, but it spawned literally out of nowhere and i'm not affected and i use windows too same version same motherboard

If you have only 3 devices connecting to internet in the house, including phones, game systems, IOT appliances, and other.....you certainly are not out of DHCP addresses.
In total there is 3 PCs, 4 Phones which aren't connected to ethernet but to the wifi so unrelated and that's it, in the DHCP thing in my router page there's only 3 actives which are the PCs

I don't i get everything you're telling me to do...
Oh sorry about that. Okay, it's pretty simple. Download this iso and write it to a disk:
https://spi.dod.mil/docs/TENS-3.0.3.1_public.iso

If you don't have an optical drive, no problem--write it to an empty usb flash drive using rufus: https://rufus.ie/fr/

Once you have your cd/usb drive ready. Shut down your computer and use the bios boot menu selection to boot off the cd/usb after you put it in the computer.

This will bring up a completely live version of linux running in ram that will not touch your drives or anything else on your computer. It has a browser so you can run some speedtests and packetlosstest.com to see if everything runs correctly or not. If it does not, I don't suspect it's a hardware issue, but some sort of network issue, although hardware can't be completely ruled out either.

Hope this helps!

Get caught up on the preceding suggestions and tests.

[Note: As for the Ethernet cable - are you able to temporarily run a longer Ethernet cable from her PC directly to the router? Thus bypassing the wall jack and patch panel connections? Or move her pc temporarily closer to the router? Problem could be the wall jack or the wire run(s) serving the wall jack.

Then the router.

This:

"Router logs are completely off topic and by that i mean they don't tell me anthing about what's happening to internet . The logs can be very revealing - maybe some entry that appears with each disconnect.

Knowing the make and model router is still necessary - the router's specs may well provide useful information. Knowing the default configuration settings for example. Some mismatch may identify the problem.

Also, again once you after you have caught up , run "ipconfig /all" again: once on her not-working pc and also on another working pc.

Post both results for comparison purposes.

Disable ipv6.

Didn't change a thing, got dc'd some minutes ago

So the specs are the following i couldn't find anything else

The Very High Speed Modem has:

4 RJ 45 Gigabit Ethernet ports (for connecting computers, game consoles etc.)
1 USB ports (to connect a printer, hard drive, USB key)
1 RJ 11 port for Telephony
1 cable entry
1 integrated wifi antenna (supporting 802.11 / g / n standards)
1 WPS button (easy Wi-Fi pairing)
1 WiFi / STBY button
1 on / off switch
1 socket to connect the power supply
1 reset button

This is my ipconfig

1) Looks like French,but even though I don't "je ne parle pas français" ,it looks like you are displaying your MAC address. Don't do that.

2) Are you sure it is not your internet connection giving you the drop outs-like a bad cable from the modem to computer/bad cable going into the modem/internet provider screwing up?

Yeah you're right thanks for telling me, yeah i'm pretty sure, as i don't have any issues and we share the same internet and motherboard

Sounds good!

Look anywhere on the modem/router for a sticker that tells the model number or part number. That will help us figure out what it is. :)
Sorry for the late answer i did check and ddn't find anything interesting but it should be modec laboxv3b sagcm, made by sagecom for SFR

also i did order a new ethernet cable just in case but i highly doubt this is the problem but i'll keep everything updated
 
I am late to this thread so it may have been answered.

What do you mean "disconnected". Do you get a red X on the ethernet icon. If you do IPCONFIG /all does it show disconnected.

This would be a hardware type of issue if that is happening.

If that is not what you mean when you say the machine is disconnected can you ping the router IP. What happens if you try to ping 8.8.8.8

The little globe with a little cross


And I will add another question:

Is NS1 or perhaps Numerical your ISP?
Numericable, bought by SFR a while ago but they are still using their servers
 
There are very few things that can cause that. In general it means you have a bad cable. It could be bad ports in the pc or the router but that is not likely. Cables are really strange when they fail. They can work intermittently, the wire will expand and contract due to heat. They can also work on some machines and not others. I would try a new cat5e or better cable. You want pure copper wire with wire size 22-24. If you are connecting via in wall wiring try to plug directly into the router just to eliminate some possibilities.

The cable arrives tomorrow in the meantime we can only wait, i'll see if it was the cable, the hardware or the router shouldn't be the cause. I'll also try to plug it in directly instead of via wall and i'll keep everything updated even if it takes some day
