I think the issue is the DNS settings as JClishe suggested above. I don't think they should point to the router, they should point to a dns server.
You can try going directly by an IP address in the address bar, for example 67.201.16.68 for flyertalk, if that works, it's the DNS settings, you are not picking up any DNS to tell the machine that flyertalk is 67.201.16.68
