I have an Apple TV as well as an airport express. I use the mirroring function in Apple TV and route everything (receiver, TV, Computer etc.) through the Airport express. I just upgraded my cable Service to include telephone. I was given the most advanced Cable TV modem. It has built in phone modem as well as a built-in router. However, upon installation I had the cable company disable the router because I wanted to continue to use my airport express. I think using my Airport Express has downgraded my internet speed considerably versus plugging the eternal cable directly into my computer. If I were to give up my airport express and use the cable provided router, do you think it would increase my speed? Also, would I still be able to get the mirroring function with the cable produced router, or do I have to have an Apple Airport Express. Even if there is no difference in performance whether I use the airport express or the built-in modem, it would still be an advantage to get rid of it because it would be one less piece of equipment and one less electrical plug in the back of my computer system. So, any advantages or disadvantages to ditching the express and using the cable supplied router? BTW: I live in a small studio. My iPhones and iPad use the wi-fi network, as does my printer and my blu-ray player.
