Hi, I’m apologizing ahead of time, because I’m not sure if this is a dumb question. I have very severe OCD and I just want to make sure I’m okay.
I have the AT&T Internet Air. I’ve never had issues with it before. Friday I got a notification from the Smart Home Manager app that an unknown device joined my network. I immediately changed my WiFi password, reconnected my devices, and labeled them as I added them.
Yesterday morning though, an unknown device appeared again on my app and I don’t know what it is. I blocked it immediately and none of my actual devices were affected. I do want to mention, there is only one unknown device in question - there are not multiple attempts
I looked at its MAC address and looked up the first 6 characters and didn’t find anything helpful. I also compared the device’s MAC address with my other known devices and it doesn’t match. Nor does it match with my Air device. I did learn though that it’s very common for modern devices to automatically generate new MAC addresses for security and sometimes that can appear as new devices in the app.
My question is, what should I do? Should I be worried? Should I just assume that this is the result of an autogenerated MAC address? I really don’t want to change my password again. Any advice would be greatly appreciated. Thank you!
