For those of you with your Christmas tree and ornaments are already up, either in the home or in the office (or maybe, in the home office) FYI: those ornaments may degrade your Wi-Fi signal by as much as 25%.  Other interesting effects ornaments may have is that they may decrease your signal distance by 10%, and given the uneven environment in your home / office, there are drops of an extra 5% that are possible as well.

So my question is — what causes the biggest interfence?  The dancing santa, the blinking Christmas lights, or that boxed robodinosaur underneath the tree?
