Interesting Christmas Fact – IT

According to research by the UK communications regulator Ofcom, the fairy lights on your Christmas tree can slow down your WiFi.

(The research also revealed that nearly 6 million homes and offices in the UK have underperforming Wi-Fi, and it’s not just fairy lights that can affect speeds: other electronic devices, including lamps, speakers, TVs and monitors can, and I believe a wet dog walking through the room will also block the signal.

I often get told that WiFi is fine for our online sessions, but now I feel justified in my statement to people, use a broadband cable.)
