Hi Manu,


Welcome to Lenovo Community!


I’m sorry to hear that the LAN and Wireless is not working as expected after updating to Windows 8.1, normally to avoid compatibility issue all the drivers should be updated when the computer is in Windows 8. Hence, I suggest you to perform “System Restore” and the follow the update procedure. Below is the link to perform “System Restore” then a link with exact Windows 8.1 upgrade procedure.


Do post us back if the issue still persists.


Best Regards

Shiva Kumar
