Network settings working but no Internet

Hello,
My Toshiba Satellite is experiencing problems. Until this week (4/1) my laptop could sign on to any network and get the internet. Now the other PC's in the house work just fine on the internet through the router but not the laptop. I have been troubleshooting and it seems that everything is working but I still cannot get the Internet to work.

So far I cannot check any Web site at all. The Diagnostics Tool in Internet Explorer gives me error "Cannot display the Webpage". The Diagnose Connection Problems on IE gives me an error on page notice. I reset the Router and still could not sign on to internet. I deleted all the Browser History files. I used Internet Explorer (No Add Ons) and still have no luck. I disabled the firewall. I checked the IP address by using CMD -r 1 www.google.com and the address starts with 190. so it seems that Windows did not assign an IP that is creating an issue. I have gone into the SysConfig and ruled out conflicting third party by going to services and startup tabs and choosing half and turning them off - checking then seeing if still experiencing problem. No luck there.
What else can I do?
Someone please help.
