Why Your Router May Fail After a Thunderstorm and How to Troubleshoot
After a thunderstorm, you may find that your router has stopped working. This article explores the reasons behind router failure during and after storms and provides troubleshooting methods to resolve the issue.
Common Reasons for Router Failure During a Thunderstorm
A thunderstorm can cause a router to stop functioning due to several factors. Here are the primary reasons:
Power Surges
Thunderstorms, often accompanied by lightning, can create power surges. These surges, when traveling through the electrical wiring, can damage the internal components of your router. Surge protectors are highly recommended to safeguard your devices from such occurrences.
Electrical Interference
Heavy storms can cause electrical interference, which can disrupt the router's operation or connectivity. This interference is often the result of disrupted frequencies and can reduce the router's performance or cause temporary or permanent failure.
Water Damage
If water enters the router or its connections, it can cause short circuits or corrosion, leading to router malfunction. It's crucial to ensure that all components remain dry and functioning properly to avoid such damages.
ISP Issues
While the issue might not be with the router itself, it could be due to problems with your Internet Service Provider (ISP). Storms can damage infrastructure like telephone poles or fiber lines, causing service outages.
Overheating
If the router is in a poorly ventilated area, heat generated during a storm, especially if it has been running continuously, can lead to overheating, causing it to malfunction. Proper ventilation and cool areas are essential for optimal router performance.
Troubleshooting Router Failure After a Thunderstorm
If your router stops working after a thunderstorm, here are some troubleshooting steps you can take:
Unplug the Router
Disconnect the router from power and wait a few minutes before plugging it back in. This gives the system a chance to reset and may resolve any temporary issues caused by the storm.
Check for Physical Damage
Inspect the router and its wiring for any visible signs of damage, such as burned components, water stains, or physical deformities. Addressing any visible damage can help in identifying the root cause of the failure.
Reset the Router
Use the reset button to restore the router to factory settings. Note that this will erase any custom configurations or settings you have made. Make sure to save any important data before resetting.
Test with Another Device
Connect a different device to the router to see if the issue is with the original router or the network. If another device functions properly, the problem may be specific to the router. Otherwise, the issue could be with the network or ISP.
Additional Considerations: Electromagnetic Pulses
Electromagnetic pulses (EMPs) can also cause router failure. A tree struck by lightning can generate an induced current strong enough to exceed the router's capacity. Your TV being fried by lightning hitting a tree nearby is a prime example. If the EMPs are particularly strong, they can either destroy the router or cause it to malfunction.
Unless you have a fiber connection to your house, there is often a copper wire carrying Internet to your router. This wire can get high voltage during lightning strikes, potentially damaging your router or causing it to crash.
The power to the entire house can also get high voltage due to various reasons when lightning strikes near the power lines. Routers, being one of the more electrically sensitive items, can be particularly susceptible to such damage.

Protecting Your Router from Future Damage
Investing in surge protectors, maintaining good ventilation, and keeping your router in a dry, cool location can significantly reduce the risk of router failure. Regularly updating your router's firmware and ensuring it is compatible with the latest network standards can also enhance its performance and durability.
Further, it is wise to have a backup plan, such as a secondary router or a mobile hotspot, in case your primary device fails.
