I bought this item after reading a review online and I must say that I was extremely impressed! It was easy to set-up and use and I had it set to go in about 5 minutes.The router is configured via a web browser and the instructions for use are excellent. That is if you even need to use them, you can usually use the standard setup and it will work just fine.It comes with a built-in firewall protection and allows a multitude of advanced configuration options even DMZ (Demilitarized Zone)It works with both standard cable modem/DSL IP configurations and PPOE setups.
