Most “wired” homes have most devices hooked up wirelessly. That’s great, the technology gets better every day. Yet, there’s nothing more stable than a network cable (rhyme unintentional). A network drop is by far the most reliable way to keep something on the network that HAS to be there. For instance, if you have a media server sharing large chunks of audio and video data to other devices, it needs a wired path to your router. You don’t want to lose the network to wireless issues right in the middle of Casablanca, especially if you’re watching it from 1,000 miles away.
