I have not seen anyone post about this in a long time but I recently purchased a Wahoo Kickr. My first few sessions worked like gangbusters however, the last couple rides I have been getting random power dropouts. I do have a video of this issue if needed. It really seems to be random as I can almost do an entire lap just fine then one lap will have several dropouts.
My setup is a Surface pro 3, Suunto Movestick with USB extension right next to the trainer, Wahoo Kickr and Tickr with current firmware.
I have referred to other posts (that’s why I now have a USB extension) but I don’t believe many are having the issue I am currently.
