Zwift freezes - "Rx fail"

(Krzysztof Kajetanowicz [TeamPL]) #1

Hey, Zwift has been freezing mid-ride, forcing me to kill it and re-open the application. This happened twice today - once after over half an hour, then another 15 minutes or so, and the partial .fit files are corrupt (both those auto-saved and those downloaded from the dashboard).

The log files are clear:

ANT  : Rx Fail on channel 1

And then a bunch of failed latency tests.

Is this because of ANT+ signal? Please tell me all I need is an extension, not a new computer…

And how do I fix the .fit files?

Rx Fail is a sign your ANT+ signal is dropping…but in your case, the freezing is because your computer is under our minimum requirements. I checked your stats in our database, and both your CPU and GPU are under spec.

If you’re in the market for a new computer, check the Alienware Alphas! They pack a lot of punch for a modest price tag. :slight_smile:

Hey Jason, as a quick update, I’m still using the obscure little netbook (yes) under spec, but the problem seems to have stopped. I have had no freezes in the las 5 workouts (5 hours). Maybe an update did something.
