I just bought a TOSLink cable to complete my wonderful ghetto home theater system (using Logitech Z-5500's), plugged in the TOSlink cable to my speakers and the TV, and my wife asks what I just did because she has no internet. I started checking things, and it turns out as soon as I unplug the TOSlink cable the wireless comes back. WTF? How the hell is an optical connection causing 2.4GHz interference?
