Cabling between nonadjacent rooms on the same floor

If your computers are on the same floor but aren't in adjacent rooms, you need to do a bit more work. The most direct and efficient cabling route is a chase along your home's beams. Most houses have beams between floors that run straight through the house, either from front to back, side to side, or both. You can usually expect a clear chase from one end to the other.

The logical way to access the chase is to drill a hole in the ceiling or floor (depending on whether the chase is above or below the level you're working on).
