Can Lightning Destroy Your Router?



If a lightning strike has ever hit your home, you know how frightening it can be. But did you know that it could have an even more damaging effect on your home network than just the potential destruction of your house? Yes, it’s true: a lightning strike can easily destroy your router, leaving you with no internet connection. So you may be wondering what steps you can take to protect your router from getting fried by lightning. In this blog post, we’ll discuss everything you need to know about why and how lightning can damage routers and provide strategies for preventing such destruction.

What is a router?

A router is a device that forwards data packets between computer networks. Routers operate at the network layer of the OSI model. A typical home or small office router can connect to up to four devices at a time and has one WAN port and four LAN ports.

What is Lightning?

Lightning is a naturally occurring electrical phenomenon characterized by the sudden appearance of a bright light in the sky, often accompanying thunder.

How does a router work?

A router is a device that connects two or more computer networks. Routers are commonly used in home and office networks to connect computers to the internet. When you connect to the internet, your computer sends data to the router, which then forwards the data to the appropriate server. The router also stores information about your computer’s location on the network so that it can route data back to you when you request it.

Routers typically have multiple Ethernet ports so that they can connect to multiple computers. They also have built-in firewall features to protect your network from malicious attacks.

Can lightning destroy your router?

Lightning is a natural phenomenon that causes an electrical discharge between the atmosphere and the ground. This discharge can be powerful enough to destroy electronic equipment, including your router. While it’s unlikely that a lightning strike will directly hit your router, it’s possible for the electrical current to travel through the wires and circuitry of the device, causing damage. If your router is struck by lightning, it’s important to unplug it immediately and contact your service provider for help.

How to Fix a Damaged Router?

If your router has been damaged by lightning, there are a few things you can do to try and fix it. First, check to see if the power cord is still intact and plugged into the outlet. If it is, then unplug it and plug it back in to reset the router. If that doesn’t work, you can try resetting the router by pressing the reset button on the back of the router. You may also need to replace the antenna if it has been damaged.

How Does Lightning Damage a Router?

Lightning can damage a router in several ways. The most direct way is if the lightning bolt hits the router directly. This can cause physical damage to the router and can also cause an electrical surge that can fry the electronics inside the router. Even if therouter is not hit directly by lightning, it can still be damaged if there is a power surge from a nearby strike. This power surge can overload the circuitry inside the router and cause it to fail. Finally, even if the router is not physically or electrically damaged by lightning, the electromagnetic pulse (EMP) from a nearby strike can disrupt the electronics inside the router and cause it to malfunction.

How to protect your router from lightning?

Lightning is a natural phenomenon that can cause serious damage to electrical equipment. Routers are particularly vulnerable to lightning strikes because they are often located outside of buildings. If your router is struck by lightning, it can fry the circuitry and render it useless.

There are several steps you can take to protect your router from lightning:

Install a surge protector: A surge protector will absorb the electrical energy from a lightning strike and prevent it from damaging your router.

Move the router indoors: If possible, move the router indoors so that it is not directly exposed to the elements.

Unplug the router during a storm: If you know a storm is coming, unplug the router and any other electronic equipment until it passes. This will prevent any damage from occurring if there is a power surge.

Keep the router away from windows: Make sure the router is not near any windows so that if there is a lightning strike, the glass will not shatter and cause additional damage.

The Effects of Lightning on a Router

If your router is hit by lightning, it can be destroyed. The electrical current from the lightning can fry the circuitry of the router. Even if the router doesn’t appear to be damaged, the heat from the lightning can cause problems over time that may not be immediately apparent. If your router is hit by lightning, it’s best to replace it.

Can You Prevent Lightning Damage to Your Router?

If you live in an area that is prone to thunderstorms, it is important to take measures to protect your router from lightning damage. One way to do this is to purchase a surge protector for your router. This will help to prevent any spikes in voltage from causing damage to your router. Another way to protect your router from lightning damage is to keep it away from windows and doors during a storm. If possible, unplug your router during a thunderstorm. This will help to prevent any power surges from damaging your router.


In conclusion, lightning can indeed destroy your router and cause significant damage to its components. Therefore, it is important to take steps to protect your electronic devices from being damaged by lightning strikes. Additionally, if you suspect that a thunderstorm may be coming soon, unplugging all of your electronics before the storm hits will help keep them safe. With some diligence and care for your equipment, you can minimize the risk of having an expensive repair bill after a lightning strike.
