reply to Bobcat I was having the same issues, and I'm using Optonline - with the 4.2.2.* DNS servers hard coded into my router. My symptoms were that it seemed I could only surf to Google - anything else and my browsing stalled. I left the 4.2.2.* servers in there, but I added a tertiary and 4th entry which are default Optonline servers. I figure that just about ANYONE can manage to run a server (or business) better than Cablevision.
