Network unidentified on my Thinkpad X200

2015-05-18, 7:50 AM

Hello! I have an old X200 laptop and it works fine but I have a huge  problem with my Ethernet connection.

 

When I try to connect to Internet using my Ethernet connection, Windows tells me that the network is "network unidentified" and I can't connect to Internet.

  • WiFi works fine for me.
  • I try to unninstall/install the drivers and disable the AMT configuration on the BIOS utility.
  • I don't receive any package
  • My O.S. is Windows 7 Home Premium 64bits
  • I have the dock with the same problem.

Thank you so much for your time.

Hi KoldoLenovo,

 

Thank you for the reply!

 

If you think the issue maybe with ATM, have you checked with uninstalling the ATM application from Control panel – Program & feature option.

 

Hope this helps.

 

Best regards,

Hemanth Kumar

Hi KoldoLenovo,

 

Welcome to Lenovo Community!

 

  • Can you verify the driver version with Lenovo support site?
  • Usually "network unidentified" error comes only when network “IP” not assigned, can you  check with configuring the “IP address” manually.

Hope this helps!

 

Best regards,

Hemanth Kumar

Hi hemanth! thank you for your reply on my post.

  • I can verify that my driver version is the last one of the Lenovo's page.
  • I have the correct IPv4 configuration with the correct LAN parameters.
  • The problem could be caused by AMT service?

Thank you so much.
