ANT data dropping in/out of ride

 Started having issues where the connection to my Garmin ANT+ stops talking to the Gamin 810.  Happened last night a couple of times.  Espaecially frustrating when trying to compete in a race and/or contesting a sprint finish.

Setup is as follows: 

Garmin ANT+ stick

Garmin 810

Garmin 2V power

Garmin hub  mounted speed sensor

PC (windows) running Zwift.

My wife also has an account and experiences the same issues.

THX in advance.

ANT+ is a very stable protocol, and has interference avoidance built into it. Most issues wth ANT+ dropouts are usually nothing to do with ANT+ itself, and more to do with the hardware on the other end. Try the tips in this KB article one by one and see if they help:

Zwift keeps dropping my signal. How do I fix it?


I noticed I would get inconsistent connections with Zwift and my Wahoo Kickr on my PC running Windows 10.  Switched to a different PC with Windows 10 but this time plugged into a USB 2.0 vs. USB 3.0 port.  Signal and connection improved dramatically.
