Tacx Neo 2T massiv drop out (ANT+)

Hi 

I just bought the Neo 2T after having a NEO org for 9 years where I have had no drop outs over ANT+ (Tacx) but now I have massive and long ones of up to 40 seconds. Same PC same ANT+ same location. Someone who has experience why and how to fix it.

Regards

Henning
