New Modem (Wireless) - how to add new wireless network to AP

[lngill26]

We recently had internet issues and had to get a new modem from AT&T and it made us create a new wireless account.  My Ruckus was already working on the old wireless account, but I'm assuming I need to add a new wireless account so I can use it with the new wireless account.  When we first moved int I had a friend help me with this, but they are no longer available to help.  I had downloaded the Ruckus Unleashed App to my phone at that time, but now I can't figure out how to log-in or don't know my username or password.  When I try to login it is saying "you are not connected to Unleashed network.  Go to settings?"  

Looking for support on how to get my new wireless network added or how I can get things to work on the app to do it myself.
