# Trainer Connection Issues

If your trainer isn't connecting to Zwift, nearby devices, outdated firmware, wireless interference, or network issues may be affecting the connection.

## Confirm Device Compatibility

Make sure:

*   You’re using the latest version of Zwift.
    
*   You’re using a supported device to run Zwift.
    
*   Your trainer has the latest firmware installed and you've power cycled the trainer after updating the firmware.
    

## Check for Connection Conflicts

Make sure:

*   Your trainer isn’t already connected to another app or device.
    
*   Any apps that may connect to your trainer are closed.
    
*   Unused Bluetooth (BLE) devices nearby are turned off or removed from the area.
    

## Check Cables

If you're using ANT+, make sure you're using a high-quality branded ANT+ dongle.

If you're using USB:

*   Use a USB 2.0 or higher data cable. Charge-only USB cables won't work.
    
*   In most cases, a standard USB 2.0 data cable is sufficient.
    

For the best connection:

*   Use good-quality cables.
    
*   Keep cable runs as short as practical.
    
*   Avoid unnecessary adapters or extensions.
    

## Check Manufacturers App

If your trainer manufacturer provides an app, check whether your trainer can connect to that app.

*   If you're unable to connect in both Zwift and the manufacturer's app, contact your trainer manufacturer for additional support.
    

## Check Internet and Power Status

Make sure:

*   Your internet connection is working.
    
*   Your trainer is plugged in.
    
*   Your trainer is powered on.
    
*   Your trainer is near the device running Zwift.
