If you found that you need to switch the network for your Spark, this can be accomplished from your ONSCREEN App with the following steps:
Open the ONSCREEN App
Click the Spark Tab at the bottom
At the bottom of the screen, you should see a red "Reset Spark" link-button
Tap that, and the Spark will restart and go back to the QR Code screen
Then you will be back to the screen that says "Let's connect your..."
Enter the appropriate network (it will default to the one that your phone is connected to) and network password, and the app will generate a new QR code
Show the QR code to the Spark's camera, and voila -- you should now be connected to the new network.
Please contact us if you have any difficulties with this process.
