Laptop Wireless problem

[Curbkiddytech]

Okay so over Christmas break I was using my dad's laptop for internet while waiting for parts for my computer to arrive. All I did on his laptop was watch Inception and get on Facebook. I was in the middle of watching Inception when I decided to get on Facebook again, and all of the sudden no pages can be found. I checked the DNS, IP, all that stuff. Everything was set dynamically, and even after I gave the laptop manual settings it wouldn't work. It's on the network and can ping all the computers and websites, but can't see any. I'm thinking it's a DNS issue but I'm not sure how to resolve the problem. Any ideas?

*I recycled the router as well, and the wired computers work just fine*

did you try "ipconfig /flushdns"

Yeah I just tried it. The prompt said the command was executed successfully but when I went back to the browser to try again I got the same "Address is not valid page"
