Having just moved my office around, I found that the location for the modem can really make a difference. I have mine on an extended USB cable, so moving it around is a lot easier. These are the results and I must say I am amazed, especially when you consider that I only moved it a foot at a time and got the best results with it wedged at the side of my UPS.

Each time I moved the modem I ran a test.

To produce the results I used Speed Connect (the latest version).
