On android when you go to the wifi settings you're currently connected to there should be a setting for randomizing mac address per connection or per network. If you change it to per connection, once you disconnect and reconnect your mac address should change. On per network, it will randomly generate the mac address for the first connection and keep that address for that wifi forever.

Most Android phones have an option to randomize MAC per WiFi, enabled by default. Maybe you can trigger a new MAC by forgetting the network and reconnecting?

on an AA flight I was recently on, they gave out free 20 mins of internet for watching a 15s ad, but this was once per device type of deal. In this case, turning on randomized mac addresses meant I get free inflight wifi for the entire flight!

You haven’t “flown” recently, have you?

Long time ago, it was probably due to overcrowding. Very easy to get shit quality of service once it hits a certain time of day.

But with advances in wireless technology (backhaul, 5Ghz, MIMO, …) I think that’s no longer the case.

Usually it asks for an email, but you can just input a fake one.

Most consumer-grade NICs have a default MAC address which is retrievable with device drivers, but delegate (Ethernet) packet assembly to the OS. If the OS asks the NIC to emit a packet, then the NIC often receives the packet as a blob, DMA'd from main memory, and emits the bytes as octets. Other NICs do manage packet assembly, but allow overwriting the default MAC address. By the time I was learning Linux, we had GNU MAC Changer available in userland with the macchanger command, and many distros have configuration for randomizing or hardcoding MAC addresses upon boot.

I want to say that this is all because olden corporate network management policies could require a technician to replace a NIC without changing the MAC address, but more likely it is because framing and packet assembly was not traditionally handed to a second controller, and was instead bit-banged or MMIO'd by the CPU.

Some devices, like Android, do this automatically. By default they have randomized mac enabled.

I mean yeah, but in this case you want to make the routers job of shutting you out more difficult.

Changing your MAC will make older messages undeliverable, but that just means the connection will be momentarily interrupted until you establish new connections after re-connecting to the WiFi.

Why not just assign yourself a different internal IP? Because a. the router probably wants to assign you one itself via DHCP; and b. the router isn't looking at your IP address to lock you out; it's looking at your MAC address.

If your IP address is where in cyberspace you are, a MAC address is who you are. If you want to fool the bouncer, change your name, not your address.

I had them most sophisticated hotel/resort wifi capture page I've ever seen them other week. It had you register on the wifi using your room number and booking email, then it gave you 10 slots that you put Mac addresses into. I couldn't imagine how many people I bet never figured out how to use it lol
