Is it Safe to Use WiFi During a Storm? Essential Safety Tips

During the monsoon season, people usually focus on outdoor risks like electricity, falling trees, or flooding. However, indoor devices—especially WiFi routers—are often overlooked. It is important to understand whether keeping WiFi on during a storm is safe.

Severe storms bring three main risks: lightning, voltage fluctuations, and sudden power surges. These surges can enter homes not only through power lines but also through broadband or fiber cables. As a result, routers, modems, and connected devices may be damaged.

What can happen if WiFi remains on?
Lightning or power surges can burn the router, damage the modem or ONT device, and even affect connected laptops or desktops. In rare cases, there is also a risk of fire. While such incidents are not common, the risk cannot be fully avoided.

Is it better to turn it off?
Yes. During severe storms—especially with frequent lightning—it is safer to turn off your WiFi router.

Is switching off enough?
No. Simply switching off the router does not guarantee protection. Power surges can still pass through electrical lines.

What is the safest option?
Unplug the router and modem from the power source. If possible, also disconnect the LAN or fiber cable. This reduces the risk of surge damage.

Should you turn it off all the time?
No. There is no need to turn off WiFi during light rain or normal weather. This precaution is mainly for thunderstorms and severe conditions.

Additional protection tips

• Use a surge protector
• Consider a UPS for backup protection
• Use quality networking devices

Just as you close windows and doors during a storm, unplugging your WiFi router is a simple step that can prevent costly damage. A short internet interruption is far less inconvenient than replacing damaged equipment.
