Thinkpad X1 Carbon Gen 7/8 No Internet Over Dock Ethernet

2021-07-21, 21:34 PM

Hello! 

 

I have a strange consistent issue with a few of my X1's. Either upon redocking, awaking from sleep, or returning from desk I'll remain connected to the LAN but lose internet connection. It'll be completely random when it happens either a couple of hours or day. I can ping anything connected to the LAN and the connection to all my network drives still work, but I can't ping google nor get anything else to load on a browser. When I release and renew my IP with ipconfig the connection restores but then ceases to work a few minutes later. When I release and renew again, it resumes working but again drops. If I connected via wifi the internet works, again.

 

When I uninstall and reinstall the drivers the internet works again but then a couple of day later the problem pops up again, we're I'm connected to the lan but can't get internet. I even put someone else on a new dell dock and the issue also popped up again. 

 

Any ideas what it could be or what I should try next? Some have not had this issue while others are consistently experiencing it.

Hello BostonCeltics,

 


Welcome to Lenovo Community

 


I suggest that you share the machine type model / MTM (ex. 81C70000RK) from the sticker as it would help us detail more about your machine variant.
It would also help running diagnostics.
Update us how it goes.

 


Regards,

I ran the diagnostics for the wired ethernet and it keeps failing even thought I'm online and connected. I can't seem to figure out why? I'm connected through the wired ethernet connection with the 40AS dock on the thunderbolt port.
