Never do a spindown in Zwift. Do the spindown calibration in the Wahoo app, and if it doesn’t work, contact Wahoo support.
The DC needs to be plugged into your router or switch, NOT a hub or pc. Make sure on the connection screen you are choosing the icon’s with the RJ45 icon and not the bluetooth one for cadence/power/controllable. The kickr’s do a auto spin down, no need for in game calibration.
The instructions and the website say that it can be connected directly to a PC.
Regardless – now everything is kinda messed up as it won’t even connect consistently via Bluetooth.
I don’t the ability to calibrate.
I need help troubleshooting all of this – I also saw a bunch of forum threads with similar issues; however, there was no technical information.
Unfortunately, my trainer is a paperweight at this stage.
Yes you can connect it directly to a PC if the two are configured appropriately. But do test it with the Wahoo app, check for firmware updates, and contact Wahoo support if you can’t interact with the trainer using the Wahoo app.
Update on my side.
So I have everything working now, DC plugged in to my router and RACE MODE available. The direct connect definitively helps, there is very minimum lag. both on the gaming side and on the actual riding side. No issues with connection; everything has been working smoothly.
Is this connectivity loss still an issue?
i just had a conection lost on the wifi while racing, which is quite anoying.
Kickr V6 latest firmware.
cheers
I’ve just had the same kickr shift… lost connection using Wi-Fi…
Is anyone else suffering from 2000w spikes? I just did a workout on trainer road on my phone using my wahoo pedals. At the same time I had my kickr v6 dircon to Zwift controlling the trainer and using virtual shifting. After an hour I started seeing more and more spikes. By the end of the workout I had 10+ on the screen at once.

There are a few reports over here. Also search the forum for “2000w” for a few more hits.

By the way, I’m curious if the behavior is any different without virtual shifting or any controllers paired.

I can give that a test tomorrow during my next workout.
No surges today without controllers & virtual shifting. I’ll try those again in tomorrow’s workout.

Hi All, I just bought a KICKR v6 about a month ago (on the advice of Shane Miller 
) and have not experienced any of the connection issues when using wifi connectivity on Zwift that spawned this discussion. But I do have an issue with my KICKR v6 generating erratic cadence values. Essentially I will be riding at a cadence of 85-90 RPM when all of a sudden the cadence value will jump into the 110-130 range. It will stay there for a while and then drop back to its correct 85-90 RPM range. I have noticed this on three recent workouts in ERG mode. It could have been happening since I first started using the trainer. But I have only noticed it recently. Anyone else experiencing this? I am using an Orbi Mesh router system with a RBR50 main router and two RBS50 satellites. One of the two RBS50 satellites is within 3 meters of the KICKR. However, I have noticed that the KICKR is connected to the RBR50 main router which is located one floor above my KICKR and quite a bit further away than the RBS50 satellite.
Update: I went into my router settings and blocked the main router from connecting to the KICKR. Then I reconnected the KICKR to my network and the KICKR connected to a satellite TWO FLOORS above where the KICKR is located. WTF! 
So, I went into my network settings again and blocked that upstairs satellite from connecting to the KICKR and reconnected the KICKR to my network. FINALLY the KICKR connected to the satellite right next to it. I haven’t tested the new network arrangement yet, but will report back IF it fixes the cadence problem. BTW, I have read that IoT devices like the KICKR are known to have this problem of not connecting to the “best” router in a network with satellite routers. I wonder how much this might explain some of the connectivity issues folks may have?
I guess you’ll find out but I’m not sure if that has anything to do with your cadence issues. Since the trainer does not have a cadence sensor built in, it is estimating it, not measuring crank arm revolutions. If it remains inaccurate you should get a real cadence sensor that you install on the crank arm.

Yeah, IoT devices generally use cheap chipsets that don’t support 802.11k/r/v standards which specifically designed for device roaming. Your kickr [any wifi device] attaching to a satellite further away is not an uncommon occurrence in mesh environments.
Mesh also does weird stuff with data in environments where time sensitivity is critical to apps so your change could help but I can’t see why from a wifi/data packet level, so I’m curious to see your results.
I’ve never seen my cadence spike on my v6 and hadn’t heard of it but I’m not across everyone’s problems either.
Paul’s spot on - I used to get cadence issues on earlier Vx model when my kickr thought I was too smooth. V6 is super reliable for me.

I’m back with some results. I did a Zwift ride in ERG mode. Unfortunately, being connected to the closest satellite did not solve the problem. After a bit of riding, my 85 RPM cadence was showing up at 117 on Zwift. I have my Garmin 1030+ running at the same time as I Zwift so I can access the left-right power balance reading the 1030+ is getting from my Assioma Duo Shi Power meter pedals (also purchased based on the advice of @GPLama 
). The cadence is also displayed on my 1030+. The 1030+ is also getting its cadence values from the Assiomas. Anyway, moving along…I then paused my ride and switched the connection to bluetooth rather than wifi. Eventually I got some wild cadence readings again. Interestingly, this time the cadence reading were much LOWER than the correct values. I then went on a free ride with no erg mode. Still had cadence issues. My conclusion is that for some cyclists, like myself, the algorithm that derives cadence off the power readings on the KICKR v6 just doesn’t do a good job. Does this make sense? I ask, because the KICKR is new and I could return it. But I don’t think anything is “wrong” with my KICKR. I think its just the nature of the beast. My plan is to select the Assiomas Power Meter Pedals for cadence on the initial pairing screen when I start a Zwift ride. The Assiomas seem to do a great job generating cadence values. Maybe they use an internal cadence sensor rather than employing an algorithm to tease out the cadence from the power reading profile. What do you think of my conclusions? Reasonable?
Yes it does. Your pedals are more like a crank arm based cadence sensor that actually measures revolutions instead of estimating based your pedal stroke.

Thanks for your feedback, Paul. It is interesting that some users (most?) experience no problems with the cadence algorithm KICKR employs, but some do. I’d love to see my power stroke graph compared to the “normal” user to have more insight into why the KICKR v6 does not work reliably for me. But in the absence of that information, I will just connect my beloved Assimos to Zwift for cadence. When I contacted Wahoo about this issue, they simply replied that my set-up was probably connecting to other devices in the background. I wonder why they didn’t also mention measuring cadence on the KICKR (and other trainers) is not always cause for celebration. Maybe they would mention that if I contacted him again and told him wifi connectivity is clearly not the problem. It’s also “interesting” that these upper-tier trainers don’t come with a crank arm cadence sensor that “talks” to the trainer with reliable cadence data rather than relying on an algorithm that can be problematic. When you’re spending over a thousand US dollars on a trainer, you would think that adding a little cadence sensor would be a small financial issue. But I guess every penny counts for these companies. Anyway, thanks again and have a good day. Lou
I think the Tacx Neo 2T/3M might be the only trainers with an actual cadence sensor built in, though sometimes a workaround is required to get it to detect the crank arm. It seems like the cadence data from the Wahoo trainers is usually pretty good but from time to time people drop in here with questions like yours.
It’s quite possible you could sweet-talk Wahoo support into sending you a cadence sensor.

Yeah, power pedals need really accurate (sub-revolution) cadence measurement because that’s one of the two variables it needs to report power values. For trainers it is more of a nice to have, my Kickr (v5) is usually pretty good but in some situations it too gets confused.
I still need to figure out how to debug my own Direct Connect, it looks at the switch like the ethernet connection is up but I can’t see the device anywhere on the network (including the Bonjour browser)…
