Does anyone know how to fix this problem? I tried biking with the kickr core and once my husband started running on the treadmill I couldn’t go. Zwift was not connected with treadmill and I had Ant+ plugged in computer.
Can you give a bit more detail?
How did you have the Kickr core connected to Zwift? Were you using ANT+ or BT and likewise what setup was your husband using. I assume he has his own account and device?
Short: Check your internet connection when using the treadmill.
Medium: If your connection is disrupted by the treadmill, you may be able to solve the problem with a surge protector.
Long answer: Some appliances, notably treadmills, send a lot of RFI interference up powerlines and into phone lines. This can disrupt anything that relies on a phone line, like DSL. Some surge protectors filter enough of this out to make a difference.
I have a similar problem - if I’m on my kickr core and my wife starts running on our Sole F80, the power levels on the trainer start fluctuating wildly. I believe this is because of interfering Bluetooth signals from the treadmill, which is automatically trying to connect to the Sole Heart Rate monitor, I think? In newer models, it looks like you may be able to disable Bluetooth on the treadmill. My older treadmill does not appear to have that capability. To get to the settings, pull the key out, press Start and Incline Up and then insert the key while holding them down.
