Devices all saying incorrect password

Internet had been working perfectly since moving into new home couple weeks ago.  We woke up this morning with issues on iphones, ipads, etc.  We "forgot network" and tried reconnecting but everything is saying incorrect password.  Reset the password through the Xfinity iOS app, still getting the same error.  Tried on our televisions, still saying incorrect password even though we've double and triple checked that we are entering the password that is shown on the iOS app.  Restarted the Gateway, still same issues when trying the new and old passwords.  Anyone have any solutions?  Were we hacked?  Did the Gateway [Edited: "Language"] out?
