Last time I went on vacation, the hotel wifi wouldn't let my laptop on for some reason, but my phone was fine. The portal to log in just wouldn't come up on my laptop.
So I took my phone off the wifi and just spoofed my phone's MAC address on the laptop. Did that for the whole week I was there.
This reminds me of college. Was downloading movie torrents on my laptop while in class, just made it so it wouldn't go to sleep when you closed the lid. So the IT guys kept kicking me off, so I'd change my MAC and keep going. It got to the point where I did that so much that the IT guys were actually going around campus looking for whoever was doing it. Also I changed my MAC so much it fried the wifi card in my laptop to the point it needed replaced lmao. Good times.
I'll probably forget to check when I get home. Does anyone know if Android randomizes the MAC address on every disconnect/connect with the random MAC option enabled?
Not by default. It remembers the MAC for each specific network. This is because sometimes you want to have specific device on the same IP all the time. The DHCP decides this via the MAC.
If you want it truly randomised every time you need to turn on non persistent MAC randomisation in the developer option.
Not quite. I'm not really sure but I think the original idea actually was a fixed hardware address but I'm not sure if a lot of devices actually ever implemented it that way because it's simpler (and cheaper) to control it in software. In modern (especially mobile) devices it's actually a security requirement because with a fixed MAC address you could be tracked by other wifi devices.
