The simplest way to turn off your wifi router at night is to unplug it from the wall, but most modern routers also let you schedule an automatic wireless shutdown so you never have to think about it. Which method works best depends on whether you just want the wifi signal off or the entire device powered down, and whether you have smart home devices that need to stay connected.
Four Ways to Shut Down Wifi at Night
You have several options, ranging from no-tech to fully automated.
- Unplug the router. Pull the power cable from the wall or the back of the router. This kills everything: wifi, wired connections, and any device that depends on your network. It’s the most thorough option but also the bluntest.
- Use a power outlet timer. Plug your router into a basic mechanical or digital outlet timer (the same kind people use for Christmas lights). Set it to cut power at, say, 11 PM and restore it at 6 AM. This costs a few dollars and requires zero technical knowledge.
- Disable wifi through the router’s admin panel. Open a web browser and type your router’s IP address, usually 192.168.0.1 or 192.168.1.1. You’ll find the address printed on a sticker on the bottom or back of the router, along with the default username and password. Once logged in, look for “Wireless Settings” or “Wi-Fi” and toggle the wireless radio off. This turns off the wifi signal while keeping the router itself running, so any wired connections stay active.
- Use your router’s app. Most newer routers from brands like Netgear, Asus, and TP-Link have companion smartphone apps. After logging in, you can toggle wifi on or off with a single tap. Some apps label this “Enable Radio” and let you control the 2.4GHz and 5GHz bands separately.
Set a Wireless Schedule for Hands-Free Control
The best long-term solution is a built-in wireless schedule, which automatically disables your wifi signal during set hours and turns it back on in the morning. Many mid-range and higher routers include this feature. On TP-Link routers, for example, you log in at tplinkwifi.net, navigate to Advanced > Wireless > Wireless Schedule, enable the feature, and then select the hours you want wifi off. The network turns itself back on automatically when the schedule ends.
Other brands put this option in slightly different places. Look under “Wireless Schedule,” “Scheduled Tasks,” or even “Parental Controls” in your router’s admin panel or app. One thing to check first: make sure your router’s internal clock is set to the correct time zone, or the schedule will fire at the wrong hours. You’ll usually find the clock settings under System Tools or Administration.
If your router doesn’t have a scheduling feature, the outlet timer method accomplishes the same thing without any software setup.
What Happens When You Power the Router Back On
Expect your router to take one to two minutes to fully boot up and restore your internet connection after being powered off. This is normal for consumer hardware. During that window, no devices will connect. In rare cases, particularly with older ISP-provided routers, startup can stretch closer to five or ten minutes. If you use a timer or schedule, just set it to restore power a few minutes before you actually need to be online.
Things to Consider Before You Commit
Smart Home Devices
Wifi cameras, smart doorbells, leak sensors, voice assistants, and smart smoke detectors all depend on your wireless network. If you power down the router at night, your security cameras stop recording and your sensors can’t send alerts. If overnight home security matters to you, use the wireless schedule method instead of unplugging, and keep security devices on a wired connection or a separate network. Alternatively, choose cameras with local storage or a cellular backup.
ISP Firmware Updates
Internet providers occasionally push firmware updates to your router using a remote management protocol called TR-069. These updates often happen during off-peak overnight hours. If your router is powered off every night, it may miss these patches, which sometimes address security vulnerabilities. This isn’t a reason to never turn off your router, but it’s worth powering it on for a full night once a week or checking for updates manually through the admin panel.
Hardware Wear
Frequent power cycling can cause gradual wear on electronic components, particularly capacitors. Routers aren’t designed for daily on-off cycles the way a light switch is. That said, the stress from once-a-day cycling is modest for modern solid-state electronics with no moving parts. If you’re concerned about longevity, using the wireless schedule feature is gentler on the hardware because the router stays powered on while only the radio signal shuts off.
Energy Savings
A typical home router draws about 10 watts and costs roughly $12 per year to run around the clock. Turning it off for eight hours a night saves about a third of that, or around $4 per year. The savings are real but small. Energy use is rarely the main reason people search for this, but it’s worth knowing the numbers are modest.
Which Method Is Best for Most People
If you want wifi off at night primarily to reduce screen time, limit kids’ internet access, or simply minimize wireless signals while you sleep, a wireless schedule is the cleanest solution. It turns off only the wifi radio, leaves wired devices and smart home gear functional (if connected by ethernet), avoids hardware wear from power cycling, and requires no daily effort after the initial setup.
If you want everything completely off, or if your router lacks a scheduling feature, a cheap outlet timer does the job reliably. Just account for the one-to-two-minute boot time in the morning and make sure you’re not cutting power to security devices you need overnight.
