My computer keeps dropping watts

I have a Kickr Core and a 2011 Mac. I am using the ANT+. It was working for the first few weeks, but now it will drop watts to – while I am riding almost every 2 minutes. As a result, I am using my Iphone. Was wondering if anyone had ideas on how to solve this issue? My zwift apps are all up to date.


Hi @Matthew_Kramer, welcome to the forums. Try dropping a log file into and see if the ant+ connection is having interference. Did you move anything around in your setup recently, like a fan?
