Mine also stopped working completely after about 2.5 years. It had network glitches the whole time I have owned it, but now it is just a big paperweight. When I turn it on, it shows a red light then rapidly flashes blue for about a minute or two, then it flashes purple forever. It never shows up on my network, and I can't change the inputs (I was hoping I could use it as a wired speaker instead). Customer service said I needed to send it to some company in Michigan. I called that company, and the rep said it would cost $200 to repair it. I bought a B&W Z2 to replace it instead. Now I want to still try and use the G-17 as a wired speaker by switching the input mode, but because the unit is frozen, and flashing, it seems I can't even do that. I have another set of Klipsh speakers (wired) and Klipsh headphones. I grew up in a Klipsh family. My father had a pair of Heresies and my (richer) uncle had a pair of Klipshchorns. The G-17 is not a shining moment for this great company. It is the Cadillac Cimarron of the audio world.
