We have our main Internet cable lying on the floor stretched across our house. It goes from the port in the kitchen, across the hall, and to the router/switch in my wife's office. It's been a safety hazard for a long time and I've been putting off fixing it, but it's time to get it done. My wife said that there were some brackets I could use to secure the cable to the wall so I could get it off the floor; what should I be looking for?
