I have a Lenovo IdeaPad Z570 laptop that i replaced the hard drive. I loaded Windows 7 Professional 64bit. I then attempted to connect to the Internet to get any updates and cannot connect. In device manager, the Ethernet Controller and the Network Controller says driver not installed (code28). I then went to the lenovo site and downloaded the driver to a usb stick and installed it on the laptop. I still have the problem. need to get some guidance on this, for it is the first time I have done this.


Let me know if this is not the correct forum for this post. Thank you.

Did You follow the Lenovo installation instructions?

Did You make sure that is the right driver? Laptops often use several different wireless cards.


The Ethernet Controller is the Physical cable network connection

The Network Controller will be the wireless hardware.
