Click on "Sites & Access Points", then click the gear icon and select "Edit" by the Access Point, and scroll to the bottom and click on the purple "Reboot" button to reset your device. NOTE: Do not press the "Reboot" button multiple times. Click it once and then physically check the SwiftReader to confirm it has rebooted.

If you are noticing the SwiftReader isn't taking any of the changes in the settings or not responding correctly, it is strongly encouraged to reboot the device first.
