Marco, I found the Bluetooth very buggy. I tested it yesterday and found the power numbers jumping around way too much for the steady cadence I was holding. Once when I got up to sprint, the power numbers dropped off to zero, so at that point I switched back to ANT+.
Lin, my new Comcast WiFi modem transmits at both 2.4 and 5GHz. One thing I did do last night (though haven’t logged in to Zwift to test) was change my laptop’s WiFi network, switching from the cable modem to the Ethernet connected Netgear router I have downstairs (which I recently set up to boost the signal for my TV). Because the laptop I’m running Zwift on is also Ethernet connecte, I never put much thought before into how the ANT+ of the Kickr, my HRM, and cadence sensor would be transmitting data to the laptop. Would it be safe to assume that although my laptop is hardwired directly to the cable modem that it is also utilizing the WiFi for the ANT+ devices?
Christopher, over the past year I’ve pretty much rebuilt the Kickr with parts Wahoo sent me in an attempt to solve the issue. I actually sent it back in to them and they changed my power control board. Wahoo suggested I do another test using their fitness app with the level set to 3 or 4. Here is their reply:
Everything I can see on the backend points to the unit preforming a designed. If you continue to experience problems with holding a high power please set the unit to a trainer difficulty or level that is not 0 and send over a fit file. Having no actual brake resistance will produce a high power number when the flywheel is spun up and it will drop off as the flywheel “outspins” the input.
Not sure how that translate to Zwift, as there is no way to adjust the “level” in game.
