The other day I found that inside the Comcast Gateway (most folks call it a router) the IPv4 address protocol (which looks like 123.123.123.123) was turned off and only IPv6 was turned on (the "v" stands for version).
The good news is that some websites such as Yahoo.com and Google.com do support both IPv4 and IPv6, but most sites don't - e.g. Cnn.com.
In my client's case, I was able to "reset" (reboot) the Gateway to solve the problem. "Reset" is the name Comcast uses. I don't recommend resetting to Factory Settings. YOU HAVE BEEN WARNED.
