We're currently aware of an issue with the Circle device where, after initially connecting to the Circle hotspot, updating the firmware, and the Circle device reboots itself, the Circle device hotspot may no longer appear in your Wi-Fi list. This makes proceeding through setup impossible as you need to connect your admin device to the hotspot to continue.
Issue: channel selection
This issue stems from the way the Circle device was programmed. In the US market (where the Circle device was initially released) Wi-Fi channels for the 2.4 GHz range are limited from 1-11. In other markets, channels go from 1-14. When the Circle device turns on, it selects the channel it will broadcast on by looking for the strongest signal around it, and then copying this channel. It does so because this channel is usually the one your router is broadcasting. Selecting the same Wi-Fi channel for the hotspot makes set up easier for the Circle device, but in certain circumstances can cause the Circle device hotspot to drop from visibility on your setup device.
Resolution: change channels and reset Circle
Currently, the resolution to this issue is to login to your router and change the 2.4 GHz network's channel to something within the 1-11 range. Then you can factory reset your Circle device and set it up again. The method for factory resetting your Circle device is available from our technical support team; they can be contacted using the information at the bottom of this page. We cannot make the factory reset instructions for the Circle device available publically at this time in order to make sure that children do not use it to reset the device.
We are currently working on a better solution to this issue and that should be available shortly. We will update this article with any changes.
