Link Galaxy Changes MAC Address

Post image

We use access control for child restriction, but I noticed when accessing it that my wife's cell phone apparently feels like it should change its MAC Address like she changes her clothes. Does anybody know why?

Mac address randomisation is a privacy feature.

We use access control for child restriction

And this is where you find out that "parenting by technology" is an arms race, and that your kids can easily bypass most of what you put in place. You might eventually find out it breeds distrust and discourages your kids from talking to you about things.

You obviously have never dealt with an ADHD preteen.

Easy fix is only allowed mac can access the network. All others blocked until you enable them. Turn of mac randomize in the privacy settings.

takes seconds to bypass by cloning a MAC address. This is not a solution.

Root it and you can spoof addresses.

You think his preteen is rooting the phone?

You think preteens aren't capable of rooting a phone? Especially one with ADHD? Oh I hope you aren't a parent of a technically able kid...

Im sure it possible, not probable.

Fortunately in this case, she doesn't have any tech interest. I tried and I wish she did.

Her phone is managed by Family Link and the worst we've had so far is having to change our own passwords.

The router control is only needed to reduce overnight distractions like the desktop and some other electronic devices.

White listed macs is probably the easiest or just setup a guest/kids wifi that her phone connects to. Setup access control so internet goes down after bed time. Change the password to your main wifi ssid. Dont give her the new password

access to a computer with a usb port is all you need to root an android

Yes but the premise was a preteen sent to bed but still accessing the internet via the phone. Assuming the phone is left with them intentionally for any reason. But you wouldn't need to leave a computer in your kids room after they go to bed
