My trainer drops connection
Your trainer "talks" to Zwift via ANT+ signal (the best option) or Bluetooth. If you're experiencing signal drops or disconnections, there are a few common issues to investigate; watch Coach Tim's video below or check out this great article on each. Zwift also supplies some helpful troubleshooting tips here.
The most common issue we see is too great a distance between your ANT+ dongle and your trainer; this can be remedied with a simple USB cable extender.
Here are a few tips:
Use Ant+ rather than Bluetooth. Bluetooth is a faster signal with greater range but is more susceptible to interference, typically coming from your laptop or computer itself. If you must use Bluetooth, find a way to get the computer as close to the trainer as possible.
Move the dongle away from the computer with a simple USB extender cable like this one.
Move the dongle close to the trainer itself to improve reception.
When you connect to Zwift and pair your trainer, make sure to use the FE-C version of the Ant+ signal.
