I never had any serious problems with Vive until now.
I previously had base stations on tripods on shelves. I finally installed them on walls on the included mounting-thingies. It worked at first, but then something weird happened. When I start SteamVR it tells me base stations are not detected - they are connected to power and the light on them is green - but they are do not "spin up", name of the channel is not detected. I power cycled them, I also power cycled my PC but it did not help (i also used "wake up all base stations").
Steam troubleshooting page was not helpful either. I did forget to power-cycle the breakout box, but other than that, what can I do? (I checked beta and non beta steamvr branch).
