During rides everything just stops for 10 -20s and when it returns I lose any progress made during the freeze. I am running Windows 7 (64bit) with an Intel Core 2 Duo E8500 @ 3.16GHz with an AMD Radeon HD 6800 graphics card.
Zwiftalizer reports my ANT is up and down like a fiddlers elbow yet I have followed all the remedies suggested and have the dongle on a quality extension and placed 1ft from the Kickr. While this would appear to be the cause I suspect that the PC / software is hanging and not reading the ANT signal. Is this possible, I would hate to be buying a new dongle if there is nothing wrong.
