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:

C:\Users\Administrator>ipconfig

I'm going to assume you've restarted the router, can you run a command prompt and type in ipconfig and tell us what your ip address is. – Col – 2013-03-30T21:56:47.220

@Col I restart the router, it's don't correct. I also added result of ipconfig command in original my question. – Sam – 2013-03-30T22:04:23.347

For some reason you haven't got a default gateway, it's possible you've set a manual ip address on your wireless card. Do you know how to change the properties of your wireless lan card? – Col – 2013-03-30T22:08:54.713

@Col No, I don't know. – Sam – 2013-03-30T22:10:13.367

If you

go to control panel then view network status and tasks.
Click Change adapter settings
Right click on the wireless network and choose properties
Double click on internet protocol v4
Make sure both settings (IP address and DNS) are set to automatic.

Wow, Thanks Col, It corrected and worked fine. Col, I have another question: Is ther any book or web site for learning network for users such as me that haven't any information from networking? – Sam – 2013-03-30T22:21:32.473

1Glad to help, as far as books go, I don't really know most of what I've picked up is just experience over 20 years of user support. w3schools.com have basic courses that cover a broad base including basic tcp/ip which is what we were looking at. – Col – 2013-03-30T22:26:44.530

Oh, yes. Really thanks for your help. – Sam – 2013-03-30T22:28:12.890

A very basic and easy to read book to begin with would be " Networking for Dummies". I'm not at all trying to suggest you are less than intelligent, its just the name of the book. I own it myself and it has a lot of good and simple explanations in it. You can often find it at a used book store for just a few bucks.
