House Wifi Logged me on anyway ?

(1/3) > >>

RJSV:
   Hello !
   I'm one of those (poor suckers) blessed with infinite curiosity, about the world's technical devices, and thus questioning the house Wifi here, after storm power blackouts.

   Bringing system back up, I noticed my Android powered phone had a text message:
   "Sign on to WIFI;  RickJames"

   OK, that made sense, as the server re-booted connection to Comcast customer here at the house.   BUT,  a couple minutes later I noticed the phone notification bar had switched from cellphone (towers I guess), back to the more usual Wifi !
   I was, like, 'Auto-logged' in, without supplying my Wifi password...nice because I was contemplating the tired old 'searching', through various random spiral notebooks....for 'Almighty Password'.   "Maybe the blue one"  I was
thinking, dreading the low-tech password backup distraction.

   Wondering, tho, why that server was so casually putting me back on the local network ?

Thanks for reading.

AFAIK, your phone wants to be online so it checks both cellular and Wi-Fi for connectivity.  It chose Wi-Fi either automatically or because you chose that as the preferred connection.

Meanwhile, computers and phones will log into Wi-Fi automatically if you checked the box that says to do that when you first set up the connection.

Just to clarify, since Ed did not spell it out: Your phone has stored the password, from when you first connected manually to that WiFi network. The network wouldn't let you in "casually" without the password.

RJSV:
   Thanks.
   I had been thinking, a theory, that the system would revert to checking that my data traffic was coming from same phone number...that sort of thing, like bank / debit cards are starting to use, including the biometric stuff.
   I keep edging up to signing up for beginner classes, here at nearby recreation dept.

Cellular data doesn't originate from your phone number, in fact, it has nothing to do with your number at all, nor do you even need a number to access data via a cellular networks (data SIMs for example). It works using regular TCP/IP like the rest of the internet.
