Computrainer unpairing every few seconds

On 8/13 Zwift downloaded what seemed to be a significant sized update. I tried to use Zwift after and my USB port keeps dropping my connection every few seconds. The green light turns off and I stop on the road. A few seconds later it comes back on and it goes again.

Hi Jim,

A few things to try:

  1. Try stopping Zwift, unplugging and then plugging in the Computrainer, and then starting Zwift again.

  2. Go through our guide on setting up the Computrainer again:–Setting-up-a-Computrainer

  3. Worse case scenario: Uninstall Zwift and then Reinstall it.

If none of these work, please submit a support ticket with our last few log.txt files and your computerspecs.txt file (both located in Documents > Zwift > Logs).


Additionally, there’s been an update to fix some ANT+ issues that might be related to yours (despite the CompuTrainer not requiring an ANT+ adapter). Please let me know if that helped at all.


Hi Eric,

The 8/14 patch fixed me up, thank you for the support.


Great to hear!

Is the patch downloading automatically on startup?

Yes, it will download when you start the program. 

Thanks Jim!

This issue seems to be back. at least with my computrainer.  Pairs and then No Signal.  Almost like loose wiring but that is not the case.  Swapped out all of my wiring and still have the issue.  Thoughts ?
