Constantly getting "server not found" from different browsers

I've been surfing the web as usual with no changes in settings, and as of 2 or 3 days ago, I have been bombarded with server not found error messages. I have seen this with Firefox and Google Chrome. I have tried doing a dnsflush in cmd prompt and I changed my settings in firefox to automatically detect network proxy settings. I am hooked up to a wireless router, then to the dsl modem. I have resetted both, and still same results. Any ideas to solve this??
