If you want a fast, stable connection, and you want to do it properly, you go wired. We all know this, but just because wired is the right answer doesn’t mean there’s no wrong way to do it. If you traipse one long cable all around the house and out to the annex, you may hit a wall you didn’t know existed. Ethernet has a hard distance ceiling, and once you pass it, things will start going wonky.
