Cannot connect to wireless network (home)

[peeush kumar]

I am having trouble connecting to my wireless router. Since the same router was connecting satisfactorily before my relocation and the other laptops can now connect to this router, it doesn't seem to be a router issue. Also, my laptop connects to other wireless networks seamlessly, it indicates nothing wrong with the laptop as well. However, I still cannot connect my laptop with this router at home: it says that the connection is available though 'No internet access'. I had used 'ipconfig/all' command to draw the following information for the guys who can help me resolve this issue:-
