Maybe someone can help me. My house has some pre-wired cat5e plugs in the walls. I have my MI424WR router upstairs and my Sony blu ray player downstairs. I first connected the router and blu ray player to the wall with cat5e cables, no luck. I then tried using a cat5e crossover cable from the router to the wall, no luck. The Sony blu ray player has everything set to auto, but do I need to configure something? Can someone help me figure out what is not working? Thank you.
