Wi-Fi vs. Christmas Lights

By December 12, 2016 Uncategorized No Comments

It’s been suggested that those lights on your Christmas tree could be affecting the speed of your broadband connection – along with other electronics.


Christian Lane, CEO of Smarter told The Sun Online: “Wi-Fi routers use radio waves to communicate with devices, usually at a 2.4GHz frequency.

“Traditional LED lights often contain a blinking circuit in each bulb to create their flashing effect.

“This paired with the poor insulation and filtering to cut costs, as well as the antenna-like nature of the long wires and a lack of industry regulation, could potentially lead to noise disruption that can interfere with the 2.4GHz WiFi band.

“However, modern LED lights often contain better qualify power supplies and an external blinking controller and thus are much less likely to cause interference.

“A way of possibly avoiding this situation is to switch to 5GHz frequency for devices where speed is critical, like notebooks, TVs and mobile phones.”

It’s not just Christmas lights that can mess up your WiFi speeds – the signal can be disrupted by anything that causes interference. This includes everything from baby monitors, microwaves, speakers – and even humans.

Christian’s comments were recently featured in The Sun online publication: https://www.thesun.co.uk/living/2286519/is-your-wifi-suddenly-running-slowly-it-could-be-down-to-your-christmas-lights/
