Rob bought an old church and he's remodeling it. He wants to install Ethernet to create a network in home. Leo says that if Rob wants Internet everywhere, the ideal time to lay down ethernet cable is when the walls are open. However, pretty much everything we do now is wireless. For music, he'll want to do wirelessly. A simple Wi-Fi analysis will show him whether Wi-Fi in his home is crowded or not. If it is, then going back to wired connections is a great idea.
