Windows 10: The Ethernet cable connection keeps falling

Suddenly, for no reason, Windows 10 drops the ethernet to "unidentified network" "No internet".

The network utility returns and gives a DNS error. I can ping by IP address, I can ping the router. I can not send a browser to the router's internal address for administration, much less to the Internet.

Ethernet cable settings

Hi Campbell,

Thank you for writing to Microsoft Community Forums.

Please reply to the follow questions to get a better understanding on the issue:

• What is the model number of your laptop?
  
• Do you have a yellow exclamation on the network icon after connecting the cat 7 cable?
  

However, you can follow the troubleshooting steps from
Fix network connection issues in Windows.

Also, I suggest you to check the laptop manual or laptop manufacturer to know whether the Ethernet port of your laptop supports cat 7 cable.

Hope it helps.

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 Cable connection in Dorms

Press start
Type in "network", and select "Network and Sharing Centre"
Click on Change Adapter Settings at the left.
Check if you have two, one ethernet and one wireles.
If you only have one, wireless, your ethernet driver is not installed (refer to website of manufacturer for driver)
If you have two, and the ethernet cable is plugged in but the adapter is not connected - buy a new cable.
Check with university site management to see if they have purposefully disabled physical network connection.
