Ant+ keeps unpairing and pairing devices regularly

My garmin picks all my sensors up perfectly however on zwift its the HR and speed sensor on back wheel that keeps unpairinf and pairing regularly.
Cadence sensor is ok though.
I cant see it being a case if moving the ant+ closer as laptop is right in front of me.
Suggestions?
I have a macbook pro and garmin is up to date.
I am fed up paying for the service and cant enjoy training. It becomes stressful and makes me angry.

Hi there,

I’d honestly suggest it very well could be the distance as there is possibly interference between the ANT+ dongle plugged into your computer and your sensors.

Try using a USB extension cable to put the ANT+ dongle underneath the bottom bracket of your bicycle - it’s where we put all of ours in the office.

Ok i have purchased one and will give it a go.
I thought with my garmin being next to the ant+ that would provide it with stronger readings

Your Garmin, does not send any data it only read what the ANT+ unit sent it you can turn off your garmin while riding on ZWIFT.

Zwift can only use what you are sending it, if you have a bad ant+ dongle, interference or a bad extension cable then Zwift cant work.
