windows 7 - My laptop connect to wireless router but wont connect to internet

My laptop has Windows 7 and connects fine when connected via an Ethernet cable to a router and my mobile works fine connected wirelessly. But, when I try to connect my laptop wirelessly, it does not connect and shows following messages: Unidentified network and No internet access

EDIT:

When I run ipconfig in command prompt I get following output:
