How to lower the cost of running a Wi-Fi router

Routers, modems and mesh nodes run 24/7, so even a 10W device uses about 7 kWh a month. A modem plus router plus two mesh nodes can add up to 30–40W of constant load. It's a good example of how always-on devices quietly add to a bill.

  • Combine modem and router into one device if your provider allows it.
  • Use only as many mesh nodes as you need for coverage.
  • Schedule Wi-Fi off overnight if no one needs it.
