Computer won't connect to internet?

I have a Gateway LT Series Netbook. I've had for about 1 year now, and ever since December 2011, it hasn't been connecting with the internet. Today, I got the courage to try to resolve my issues, though I'm not an expert at these things. So far I've changed my TCP/IP Propeties to 'Use the following IP address' and 'Use the following DNS server addresses' options. I manually inserted my IP address and subnet mask. I have no default gateway and use the DNS Servers 24.25.227.55 &
24.25.227.53
My actions have caused me to gain a well internet connection but, the only problem is I can't get to the internet itself using google chrome. It has the 'DNS server lookup failed' error. I've tried other DNS Servers such as the google: 8.8.8.8. I still don't know why my computer says my connection isn't active. My iphone is currently using the Wi-Fi i'm trying to connect too, and I've tried restarting the router but still nothing. Any ideas why?
