ALERT: Odd warning over Christmas decorations that could slow down your internet

A warning has been issued over three common Christmas decorations that could be blocking your internet signal at home.

Virgin Media has shared how your Christmas decorations could be slowing down your WIFI, and ways to avoid it.

According to new research from Virgin Media, "nearly two thirds (59%) of festive fanatics put their Christmas lights in the same room as their broadband router which could interfere with their WiFi." 

Fairy lights 

Fairy lights, according to Virgin Media, "create electromagnetic interference that disrupts your Wi-Fi signal. This happens because these lights emit frequencies that overlap with those used by your router, particularly if they’re blinking or in close proximity to the device. This results in slower speeds and buffering when you’re trying to stream your favourite Christmas movie."

What to do:

Place your router as far away from fairy lights as possible and consider using LED lights with lower interference potential.

Tinsel: 

Tinsel's "metallic surface reflects Wi-Fi signals, causing them to bounce away from where they’re needed. This can create “dead zones” where your internet connection weakens." 

What to do:

Avoid decorating your router with tinsel or other metallic objects. Use non-metallic decor near areas where you need strong Wi-Fi speed. 

Christmas tree: 

Your Christmas tree, especially when covered in lights and ornaments, can block Wi-Fi signals if it’s too close to your router. The tree itself and all the decorations on it can reduce the strength of your connection. 

What to do:

Position your tree and router in separate areas. If your router is centrally located for optimal coverage, ensure the tree isn’t directly in its path.

Virgin Media have also said that "devices like microwaves and baby monitors can also interfere with your Wi-Fi signal."
