[jackcnd]

i got a ideapad y570, and i upgraded to windows 7 ultimate, and now the ethernet does not work (wireless works). i tried uninstalling and reinstalling the drivers.  can someone help?

[yigit]

check device manager if there is non-installed device first. ( yellow marked )
by the way, did you change the versions? ( 32 > 64 )

[jackcnd]

yes i have the 64 bit version.

and the driver is correctly installed, but it still does not work

Hi jackcnd

1. try redownload and reinstall the drivers

2. go to Network and Sharing Center, Local Area Connection, Properties, double-click Internet Protocol Version 4 (TCP / IPv4), ensure Obtain an IP address automatically and Obtain DNS Server address automatically is checked.

Hopefully it works for you.

Cheers!
