Windows 10: Random Disconnection Ethernet

Hello, I randomly get disconnected from the internet. I couldn't pinpoint the cause.

The computer with the IP address 169.254.38.155 did not allow the name to be claimed by this computer.The name "PCNAME :0"

- ipv6 deselected from the connection properties of the network card
- static ip and opendns set
- reset from cmd
ipconfig /release --- ipconfig /flushdns --- ipconfig /renew --- netsh int ip reset --- netsh winsock reset

Constantly disconnecting with ethernet cable

Hello,

Thank you for keeping us posted on the status of the issue.

I suggest you to check if rolling back the Ethernet driver helps to resolve the issue. Follow the below steps.

• First of all, Press Windows logo + R from keyboard. It will open
  RUN.
• Now type devmgmt.msc and press Enter to open Device Manager.
• You will see all the device list of your PC. Expand Network Adapters

Rollback driver

Double click on your Ethernet driver in Device Manager. Then Click on
Driver tab and select Rollback.

Important: If your drive is performing well and there is no error, Rollback driver button will be grayed out as an option.

If it still does not help, I suggest you to reinstall the drivers for the Ethernet driver and check if it helps to resolve the issue.

Note: Once you uninstall the drivers the Ethernet adapter device will be disabled and you won’t be able to connect to internet. So it is advisable to keep all the installer files as a back up in your hard drive.

Write to us with the results for further assistance.

Thank You.

 

Ethernet constant disconnects - NetworkProfile EventID 10001

Hello there,

After hours of searching & trying to fix my constant disconnect issues in vain, I chose to ask for your help here.

Setup:

• Desktop PC connected by ethernet
  
• Realtek Gaming 2.5GbE Family controller
  
• Last gen "Orange" livebox 6 router (french ISP) on a optic fibre connection
  

Problem:

• In certain cases (video calls with slack/teams/other, while online gaming) there are constant disconnects. Connection is constant otherwise.
  
• The connection drops for a few seconds, then comes back up
  
• Only applies to ethernet, wifi isn't affected
  
• This can happen every few minutes, dozens of minutes, or hours, it seems completely random
  

I did find all the entries in the log that correspond to every disconnect I've had, under Microsoft > Windows > NetworkProfile

For each disconnect I've got the same few entries in this order for provider Microsoft-Windows-NetworkProfile:

eventID 10001 > 4004 > 20002 > 4001 (pending identification) > 1000 > 4004 > 4002 (pending identification) > 20002 > 4004

I found various posts listing fixes to what seemed to be my problem but none worked for me (ethernet controller power saving modes, DNS wpad resolution fails, cpu offload...etc...).

Thanks a ton for your help!!
