How to upgrade router when you don't have a cell phone with a data plan?
I just got the new white router. And as I understand it, I'm supposed to use the Xfinity app to help me set up the new equipment. But if I disconnect the old router, I won't have any access to the internet (my cell phone and tablet are wi-fi only -- no data plan). So how will this app work without internet access? I'll call Xfinity tomorrow during business hours before I start this, but just in case someone else already went through this, I'd love to know beforehand how to do this. I want to set the thing up with all my current parameters -- names and passwords -- so I don't have to reconfigure a million devices around the house.
