I cannot sign in to the admin page. No matter what device my jetpack is connected to, the http://my.jetpack or 192.168.1.1 methods do NOT work. Error message every single time. Every single time, no matter what. Do not tell me to do a reset because I have already done a reset over a dozen times.
We definitely want you to be able to access your Jetpack in order to better manage it! I'm not having much luck in finding a Jetpack with the model number RC400L-CD. Can you double check the Make and Model of the device you are trying to use?
