Agreed,
You are worrying about something that you need not worry about. The wireless connection is from your USB dongle to the wireless transmitter, which is in turn received by your wireless receivers on your LYNX equipment. All you are transmitting is DMX data, there is no connection back into your home IP based wireless network. I don't think there is much to worry about from an interference standpoint either. But, if you experience any glitching, just change to another of the 3 channel options.
I live in a neighborhood with a lot of wireless access points in close proximity to my house and I do not have any issues with interference.
