xfinity xb3

Is There a way to reauthenticate your xb3 modem without using customer reps who have been great in helping me i might have to get a smart phone to use the xfinity xfi app but if that was not available what tool would i use when i go to the 10.0.0.1 everytime it gives me a spinning wheel with no prompt to set up like it did on my other cable modem my old one was about 7 yrs old and wouldn't let ps3 connection work anymore.
