Power meter not responding correctly

I finally got a power meter, (been using a speed sensor), and it is recognized but won’t stay connected.  I know all the troubleshooting tips, and have done everything to try to remedy this problem.  

I have tried with my macbook, and the app.  I have an ant usb for the computer.  It’s recognized by my garmin fenix, as well, but I really want to use Zwift.  

I’ve turned off my watch, disconnected my phone, turned off the fan, checked internet, turned off speed sensor, etc.  The speed sensor worked fine, so it has to be the meter.


Any suggestions?

What is the make/model of the power meter? Is the firmware up to date on the power meter? Are you using a USB extension cable to get the ANT+ dongle as close to the power meter as possible?
