Before you start ripping down your holiday cheer, keep in mind that virtually any electronic device can eff with your internet connection. The UK's independent communications regulator Ofcom has released a study that shows how household objects might be interfering with your WiFi, reports Science Alert. Umm, annoying.
It's not just Christmas lights, according to writer Andrew Smith in an article originally written for The Conversation: Home electronics and microwaves as well as steel, concrete and foil building materials can also mess with your router. And did we mention its location in your home has a lot to do with your connection, too?
Luckily, Andrew says that he hasn't heard of any cases where people's WiFi was actually strongly affected by holiday decorations, although he admits it is possible:
We'd say you're safe to deck your dorm with lots of twinkle lights! Fa-la-la-la-la-la-la-la-la.
"Most fairy lights [that's Brit speak for Christmas lights] have unshielded wires, which means there's no radio frequency insulation to protect radio-based devices from the electromagnetic effects of the power cables trailing around your tree," Andrew writes.
