Yeah - day -1 in new house, get internet. ATT modem, tech has me scan a QR code to login to this WiFi via my iPhone. (I have a mesh network but hadn’t moved belongings, this was just making sure service was working.)
Couple days later, we had moved belongings and setup an old dumb TV for my kid. I was a bit surprised when then Apple TV had the WiFi credentials but I was busy moving and just shrugged it off.
Couple days later, I replaced the old dumb TV with a new Samsung. It had connectivity too, without doing anything specific. This isn’t my first smart TV but I never give any TV my WiFi and instead always use the Apple TV devices. So was a little more shocked on this one but thought I’ll figure it out when I setup my mesh.
Over the next few days, the JennAir appliances showed signs of connectivity. I wasn’t sure how. Hadn’t intended on giving them any Internet access. Don’t really care about having a smart oven.
About 2 weeks later, I get around to setting up the mesh. Start going device by device and having it forget the ATT routers Wi-Fi. None of the devices know my mesh info, so set them up individually. I need to just disable the ATT routers Wi-Fi network, haven’t yet.
I’m not really a networking guru. I just never had this happen before. I think I either accidentally allowed my phone to share the information or it’s possible my wife did. I had never used QR to login, so maybe that exposed something.
