DSN + DSL problem

  1. Okay, here's the story..
    Last night I was working on a project for school and I had put paper over my laptop screen to trace an image. In the middle of doing that a window pops up. I couldn't read it because of the paper covering the screen and I assumed it was just an update message for one of my smaller programs, so I just clicked ESC without reading the message. That's when the problem started.
    When I had finished tracing I tried to go online but I kept getting an error message saying:
    The server at www.google.com can't be found, because the DNS lookup failed. DNS is the web service that translates a website's name to its internet address. This error is most often caused by having no connection to the internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chrome from accessing the network. (ect) And then at the end - Error 105 (net::ERR_NAME_NOT_RESOLVED): Unable to resolve the server's DNS address

    I then tried accessing the internet on my phone but it couldn't connect either. I looked at my router (Zyxel) and noticed that the DSL light was out. I turned it on an off, played around with the wires, made sure all were connected, reset the router but nothing has worked. I looked at it this morning and the WLAN light is also out so I only have 2 green lights on it now.

    I think I may have found the problem but I'm not 100% sure on how to fix it. I'm writing this on another laptop with my laptop next to it and I'm comparing the ipconfig /all information and I notice that my DNS servers are in a mess.
    Here is the info..

    I'm pretty sure the DNS servers are not supposed to be fec0:0:0:ffff::.
    Could there be a link to this and the DSL going out? I can't access the Internet at all at home now and I have a tech guy from the phone company coming over on Friday if I haven't solved this before then but I'd rather save myself the money and just fix this on my own. I'm using Windows 7 by the way.

    Thanks in advance :)

    The RED items are a major impact and cause the BLUE result

    You *MUST* have DHCP enabled to get a valid IPv4 and Gateway

    To fix the above:

    Start > "View network connections" > Right-click on the 'local area network' > Click 'Internet protocol version 4' > Click 'Properties' > Ensure the boxes are ticket next to 'obtain automatically'.
