Win10: Ethernet issues: random disconnections

Hello,

For some time now, I've been experiencing a problem likely related to my Ethernet network card or due to some configuration conflict somewhere.

I have a wired Internet connection via Ethernet cable. My ISP is Bouygues Telecom, and I have fiber.
However, my connection keeps faltering; several times a minute, the logo in the bottom right indicates that my internet connection is dropped before reconnecting by itself. In the Network Center of Windows 10, the Internet connection is indicated as "Ethernet, Private Network" when the connection is established and "Not connected - No network" as soon as there's a drop. My Ethernet card is as follows: Realtek PCIe FE Family Controller. The following cards are also listed in Device Manager: TAP-Windows Adapter V9 and VPN Client Adapter - VPN. Disabling these does not change the problem.

I tried to update the drivers for the Realtek card, but apparently, everything is up to date. I also used the option to reset the network settings available in the Network Center in Windows, and each time I attempt the diagnostic tool, the connection has time to recover during the analysis, and it indicates that there are no problems.

When I'm browsing the internet, at each drop, Chrome indicates that a "Network change has been detected." I should also point out that these cuts, very frequent (several times a minute), tend to occur even more frequently with each page load or form submission.

So there you go, I'm really not savvy on all this network stuff. I had read on several forums that it was necessary to disable the power-saving option of the network card, which I did, and that yielded no results. I don’t know what to do anymore.

Thanks in advance if you have any leads!

Configuration: Windows / Chrome 71.0.3578.98

Hello,

Personally, I had to fix a flaky connection for someone and that was enough!

Open a command prompt as administrator and type each of these commands:

ipconfig /release [Enter]
ipconfig /flushdns [Enter]
netsh winsock reset [Enter]
ipconfig /renew [Enter]

Then restart.

And let us know if there is any improvement :)

A little thank you to the site volunteers costs nothing, just like marking a topic as resolved when it is :)

It's intermittent apparently, not the same issue as what you saw.
Either the driver, or connectivity, but not configuration.
Either hardware a bit worn, network socket or cable.

Yes, it was intermittent too.

There's no risk in testing anyway :)

Good evening, thank you for your replies.
I had already tried the command "netsh winsock reset," which on several occasions has managed to fix issues with my wi-fi connection, but for the problems with the Ethernet connection, it didn't change anything.

I'm still going to try the other commands, just in case. I'm also going to buy a new Ethernet cable tomorrow to see if that's the issue, you never know, even though I would be surprised; I have a new cable that came with my box, and no rodent pets in the house, so theoretically, the cable is fine ^^

Well, I tried the commands in the command prompt, in administrator mode. It didn't solve the problem for the Ethernet connection.

Try to check if any rules on your box/router are complicating the connection.

Otherwise, try putting your PC in DMZ zone on your router (just for testing), or even disabling your firewall.

All of this at the same time, then gradually putting everything back to normal to see where the issue might be.
