Because there is a monthly fee, if you do not plan to use Firefly for the next several months you can delete Firefly from your www.usb7.net account, and your account will not be charged after current billing period.
Several months later, if you plan to use Firefly again, please visit Firefly by entering 172.16.10.1 and click "Go to register" button to re-register Firefly with your www.usb7.net account.
