How Your Christmas Lights Could Be Killing WiFi Signal

Every year we hear the experts warning everyone how careful they need to be with their Christmas lights because they could cause a short circuit. But you don't hear them reminding everyone how their Christmas lights are killing their WiFi signal.

That's right, those beautiful twinkling lights are keeping a dark secret affecting your internet connection. The secret is that they emit their own waves which do not allow your Wi-Fi connection to work at its maximum. You've probably had enough trouble with your ISP for the rest of the year, and the last thing you need is for your Christmas lights to be hurting your connection as well.

How to get a better singal

To get the most out of your WiFi signal, you may want to move your router away from your Christmas lights, electronics, and maybe even use the Ethernet cable. Place your router in a secluded area, away from your everyday devices, so the baby monitor waves don't interfere with you from streaming the latest episode of Big Bang Theory.

If you decorate your tree with a decent amount of lights, your WiFi signal might not be affected too much, but the more lights you add, the greater the interference. So making your tree the new sun wouldn't be such a good idea, at least for your internet connection. Christmas lights are generally unshielded, and that's why the lights can affect your signal.

You can also avoid having too many devices on (besides your lights) because your WiFi signal can completely disappear if too many signals are getting in your way. Since your WiFi and devices like your smartphone operate in a certain range of the electromagnetic spectrum, it's easy for their signals to get mixed up. Christmas lights do not directly harm your WiFi, but they do damage the radio frequency signals emitted by the flow of electricity.

You should also keep in mind that the thickness of the walls in your home also impacts your WiFi signal if you have the router in another room. Also, if there is another WiFi signal too close to yours, it can also affect your signal. If you add this to your Christmas lights, you might be wondering how you can always check your Instagram profile.

Flashing Christmas lights are also to blame since they disrupt the electrical juice that is given to your router. The interference you might experience might not stop you from browsing the web, but chances are the voice communication software you're using is having problems.
