xfinity wifi works but XFINITY says wrong password
I hope I can make this clear: When I got Xfinity Mobile (Aug 2018) - I bought a new phone at the Comcast Store and the sales person set up both xfinity wifi and XFINITY. He explained that XFINITY is secure so to try to use that whenever possible when outside of my home network. I have Xfinity wifi at home and it shows my home network, xfinity and XFINITY. I have always been able to join any of the three. Today - while trying to fix a problem with Safari on my iphone - I tried to join XFINITY and it said "wrong password". When I looked - the user name was a string of numbers. I tried my home network password and it did not work. I have no idea why it would randomly stop working after almost two years. If anyone know how to fix this - I would appreciate any help. Thank you.
