Recently I installed a new OS windows 7 to my laptop lenovo z570,then I installed all the drivers required . But when now I plug my Ethernet cable it shows connected to unidentified network No Internet Connection . From the same modem I can access internet in my mobile through WiFi....please help me fixing this issue

Try the easiest fix first. Download THIS free utility and change the MAC address of the Ethernet adapter.

Other fixes are much more hit and miss and even a clean reinstall will often not fix the unidentified network issue in W7. If this fails we will move on to other things that are more effort.
