Slow WiFi? It's probably your fairy lights

Christmas tree lights signal

You know how it is, you put up your tree (probably a crappy one because those bad boys are expensive), stick up some baubles and fairy lights, then sit back and relax in a christmassy glow. But then, as you go to stream Christmas films (or porn) online, it takes forever because your WiFi is horribly slow. #Christmasproblems.

Sure, this sounds like a load of rubbish, but it genuinely isn't. Ofcom did some tests that prove it does. In fact, around six million homes and offices could improve their broadband connection because they've set up things that interfere with their signal.

Ofcom say: “the app tests the Wi-Fi set-up and, if it finds a problem, will provide some troubleshooting tips to help improve broadband. For example, it may suggest you: move your router away from electrical devices: Halogen lamps, electrical dimmer switches, stereo or computer speakers, fairy lights, TVs and monitors and AC power cords have all been known to cause interference to broadband routers. Keep your router as far away as possible from other electrical devices as well as those which emit wireless signals such as baby monitors etc.”

“Move your router to a different part of your home: The walls and furniture in your house act as an obstacle to the Wi-Fi radio frequencies. Ideally routers should be kept centrally within the home and placed on a table or shelf rather than on the floor”

There's even a free app from Ofcom, so you can so you can test your coverage! Ho! Ho! Ho!
