In a bit of a followup to an earlier thread (viewtopic.php?f=29&t=118310
) I have recently come to discover that there is a little known but documented issue with External hard drives that run off a USB 3.0 cables where the signal across the cable can cause significant disruption of wireless signals.

In my own experience, a WD external drive plugged in to a front I/O USB 3.0 port on my media server was interfering with my wireless keyboard and mouse plugged into the same device. After upgrading the equipment to Bluetooth and having the same issues I realized it wasn't my or my neighbors WiFi causing the disruption. The issue was eventualy resolved after I got fed-up with how the media center looked with the USB harddrive dangling off the front of it and routed a USB 2.0 Hub to a cabinet where i could hide such devices. The keyboard instantly started working again with no appearance of any latency or interference. I did some more troubleshooting to verify my findings then a bit of google searching later and I found confirmation of my suspicions in the article I linked above.
I am sure some of you gerbils have heard of this one before but I certainly haven't so I felt like sharing and spreading the word. Hopefully my experience can save someone else some money or at least a headache.
