3 Ways to Cut Your Wi-Fi Router Energy Bill
- 🌱
Disable unused frequency bands — if all your devices use 5 GHz, turning off the 2.4 GHz radio saves 1–2W.
- 💡
Turn off the router's built-in LED lights if it has that option — they're unnecessary and draw a small constant current.
- ⚡
Schedule the guest Wi-Fi network to turn off during hours you don't need it, reducing processor load.
Startup Surge Information
Routers are solid-state devices with no motors, drawing very consistent, low wattage with no startup surge.
