My broadband got disconnected accidentally the other day

3. Good guess. It's frighteningly easy if the map/labeling is wrong or confusing.

The phone company workers have an easier time at it because there's a standard order for using twisted pairs based on colors and stripes. Within a building, coax is coax (other than grade). It can be a bloody mess.

On a personal note, I hook a rubber band around each end of a cable (like making rubber band chains) and use a file folder label folded over the end loop to keep it in place and let me label the cable. That makes it far easier than tracing back wires to see where the HELL they came from. It's also a lot easier to relabel them if you change the purpose of a device or replace it with a new one (like a printer).
