I have a few systems in my house, Mac and PC. I have a laptop I boot up using a USB Ubuntu distribution. Everything was working fine, but now I can't find the Internet.

When I right click on "Connection Information", the DNS settings for the primary and secondary match what's listed on my router. I can browse content from my NAS drives, but I can't seem to resolve addresses from the web (in chrome, in firefox).

It's kind of a strange thing, does anyone have a guess?
