I would never even pretend to know much about technology but I can definitely say I would of never thought that Christmas lights could slow down your Wi-Fi signal. Guess you learn something new everyday. - Chubbs
Experts say everyday household objects, including fish tanks and even Christmas tree lights, can interfere with your Internet connection.
They say placing your router near any electronic device, including a fish tank, TV or baby monitor, can drop WiFi speeds. This is because these electrical appliances transmit radio waves, which are similar to the signals sent out by your wireless router.
And to ensure your WiFi is the fastest possible, make sure your router is plugged into your master socket, which is usually found where the phone line enters the house.
