Windows 7: Cant connect to Internet

I currently have two laptops in my house.
At first I thought that it was the ISP but it has been a week since then and I stll got no internet, but my sister told me that her laptop has internet (this one that I´m currently using) so its the other laptop's... Ive tried the winsocket thing and still no results, when I ran Windows Troubleshooting I got a DNS server not responding error so I used OpenDNS and even Google's dns but still no results... Then I got a cant connect to Microsoft Windows error and after some tweaking the error change to restart the modem wait 10 seconds blah blah blah.... My brother keeps bugging me saying that formatting is the only option and I told him that it must be the laptop's configuration but... Is there really no other way to fix this?
Heres my ipconfig /all I hope someone can help me fix this...

Hello and welcome Wilfredo Just to be absolutely sure - you did have the net running on both machines? and have you changed anything just lately?

One thing you can try is the device manager in control panel and check the driver for the network adaptor in both. If you are not familiar with that let us know.

Um frgot some specs on the laptops would be good my friend

I didn't have both connected with internet. I was using wired connection.

Yep thats what I meant my friend and it might be worth looking in the Device Manager to see the status of the LAN adaptor.(see pic)

Some details re the machines Wifredo would be good mate - specs model etc

Hi there....

In addition, it might be worth it to uninstall the network driver from your Device Manager then install the latest driver that you may download from the manufacturer's site.

Also, what type of Anti-Virus or Security program are you using - McAfee, Norton,Webroot, etc...?

Please give us an update.
