Tacx Neo2T resistance not working

Equipment

Hello. Posting to see if anyone else has similar issues or solutions to something I recently started experiencing…

I have had my Neo2T for about 5 years more or less issue-free. Recently, i have started having a problem where the resistance is failing to engage. I am running the latest firmware and TR app, and I do all of my workouts on my laptop with a Bluetooth connection. I first experienced this issue about 2 weeks ago. I had almost given up on the trainer, but then it magically started working again with no issue until this morning.

For example, when I boot up my trainerroad workout and start pedaling, the power seems to be “stuck” at around 70 watts no matter how fast or slow I pedal. I can see that the trainer is connected because the watts and cadence will fluctuate. I’ve tried testing at different target power ranges by skipping ahead in the workout, but no matter what the target power is, the trainer will hoover at ~70 watts. I even tried switching to resistance mode, and even at max resistance in my hardest gearing it will still be at around 70 watts.

I have had interference issues with the trainer in the past so to rule this out I turned off bluetooth on all my other devices, and have it in a separate room from my WiFi router. I’m thinking it is a problem with the trainer itself. The issue is happening across multiple devices and applications. The only way I have found to affect the resistance is to connect it to my Garmin bike computer, and manually set the target power. It will work for a few seconds and then revert to the default 50 Watts.

My next troubleshooting step is going to be to order an ANT USB dongle and see if I have any luck with that. In the meantime, does anyone have any ideas on what may be causing this?

Update: I found an ANT dongle in my junk drawer, and it seems to be working correctly with that. I already wasted too much time troubleshooting, so will not have time to do my workout today :frowning: Still would like to get the bluetooth issues figured out.

This may not be your issue because it sounds like a new occurrence, and it’s BT you’re having an issue with, but:

I have an ANT+ Tablet that I use sometimes, and I will frequently have that behavior until I start the workout (has to be like 1s in) unpair the trainer, re-pair the trainer, and then sometimes still have to close the app, re-open and it asks if you want to resume the workout. Never had it not work by some combination of the re-pairing and fully closing / re-opening the app / resuming the in-process workout.

Never happens with the old iPhone I use to control my 2T most of the time, but with the tablet it’s frequent.

The fact that this is happening across multiple devices and applications makes me think this is an issue with the trainer itself… Have you tried reaching out to Garmin Support about this problem?

I had a similar issue with the OG Neo. I tried everything like you, and then I realised that the trainer had been powered up for about 2 years. Sorry if this is super obvious (it wasn’t for me!), tuning the power off and on fixed my problem.
