Kickr won’t pair anymore

After a couple years of Zwift my Kickr has suddenly stopped pairing via Ant+. My cadence and Tickr still pair. The kickr can be found instantly on the wahoo fitness app so the trainer can’t be broken. Very frustrating!! Anybody had similar issues?

Oh no, sorry to hear Zwift is giving you some trouble David! For starters have you tried out our ANT + troubleshooting guide?

I’d also check if your Kickr’s firmware is up to date.

Hi. The Kickr firmware is up to date. The Ant+ stick is plugged into my laptop which is only a couple feet away from the trainer. I don’t have an extension for the Ant+ as it’s never been necessary. I’ve recently changed my internet provider and it’s very slow. I wonder if that could be the issue?

Hmm… are you able to pair via Bluetooth with your Zwift companion app?

Yes but it’s not that reliable…sometimes it’ll pair instantly but other times not. I’ve read on here about unpairing from the wahoo fitness app…I’ll try that

Checking in, are you able to pair now? Yes, your Kickr should be paired straight to Zwift without being paired to anything else.

Hi. Yes I’m able to pair via Bluetooth. Ant+ no longer pairs but hopefully I’ll get by with Bluetooth. Thanks for the help

Hi. For some reason when trying to pair my devices today nothing would pair. On the paired devices screen neither the Bluetooth icon or Ant+ icon were emitting circles. Any ideas?


I’ve had a problem with the Paired Devices screen not emitting circles in the top left on either Ant+ or Bluetooth. I’ve totally lost connection to my trainer via Ant+ but Bluetooth worked fine the previous day and I’ve changed nothing. Any ideas?


Hey David, can you send us a support conversation? (
It would be a huge help if you sent us your log files as well, so our team can try to track what’s causing these pairing issues.

Here’s a guide on how to find your log files:


My laptop is ancient and I’m struggling to send my Zwift logs to my email. I’ll persevere and hope to send these to you asap


No problem, let us know if you aren’t able to provide log files at all!

This happened to me just the other day. It just stopped. It is the ANT+ in windows that has stopped, and i couldnt re-install it. dumbass ANT+ site require register and login to get download for reinstall. I did however have another ANT+ dongle, which i swapped, and it installed itself correctly rectifying the issue. Kickr saw the new ANT+ and away i went.

Seems strange that the Ant+ dongle picks up the Tickr and cadence sensors but not the Kickr

Hello, this just happened to me today. I have a KickR original. I have disconnected the trainer for more than 30 seconds and reconnected. It pairs to the Wahoo app on my phone and Garmin connect via Bluetooth (images below) but it won’t pair with Zwift so I can’t use the program! It was working fine yesterday? Please help?

Hey @Brooke_Lazich, welcome to the forums.

It would be helpful to know how you are pairing (to Companion App or direct to a Zwift platform), and what platform you run Zwift on. EDIT: also double-check that you have force closed the Wahoo and Garmin Connect app’s on your phone - they may be grabbing the signal before Zwift has a chance.
