As each holiday season approaches, it’s not uncommon to read warnings about Chistmas lights slowing WiFi down. Some people believe that these decorations have a major impact on Wireless Internet speeds, but is this really true? Depending on various factors, interference from Christmas Lights may or may not actually affect your connection.

How it Works

Wireless Internet equipment communicates with your computer and other devices via radio waves. Many electronics and machines produce interference that can reduce data transfer speeds. Holiday light sets do this to a limited degree, so they have the potential to affect wireless communications.
