I had a comic along the same lines at my door and I aggressively applied the 2 min rule. If I can answer your question in 2 min, I will, otherwise I will ask them to set up time on my calendar.
Made for some initial friction, but eventually everyone got it.
Remote has been so great because I just block off my calendar accordingly and turn off notifications.
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
Oh I know that. Common verification joke people use.
I’ve never been asked for any information to use airport wifi, that’s why I was wondering where they do ask.
In general, I thought IP addresses are mutable while MACs stay the same, and I thought that’s why the outside world uses IPs to identify networks while routers inside a network use MACs to identify specific devices. If you can change your MAC arbitrarily, doesn’t that risk making the router’s job more difficult? Why not just assign yourself a different internal IP?
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.
The router recognizes a device based on its MAC and assigns an IP address. Traditionally, the MAC stays the same, so you’re right. In this case, OP doesn’t want to be recognized by the (airport) router. There is software for spoofing the MAC address for most platforms. Changing the MAC address has recently become more popular due to privacy concerns and on some operating systems it’s supported out of the box.
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.
Thanks for asking the question! I’ve never needed to know it, and I’ve done enough android tinkering that I’m fairly sure I could find it quite easily if needed, but I enjoy my social media being peppered with bits of learning wherever possible. I’m a big fan of ambient curiosity
Yeah, recently I was on school wifi and it kept bothering me to log in and figured I needed to switch to per network or it would bother me everytime to sign into the captive portal.
Yeah, on Android 12 I can only choose between “randomized MAC” and “phone MAC”. Doesn’t specify if it’s randomized per network or connection, but I’d guess it’s per network.
By default it’s per network, but if you enable Developer Options, there is a setting under Networking called “Wi-Fi non-persistent MAC randomization” that randomizes the MAC per connection for networks that have randomization enabled. I am on Android 13 though, so I’m not sure if 12 has this option.
On stock (Pixel) Android, if you enable Developer Options, there is a setting under Networking called “Wi-Fi non-persistent MAC randomization” that randomizes the MAC per connection for networks that have randomization enabled.
I have a Samsung and it’s per network, even if you forget and rejoin it keeps the same random Mac address. You need to enable a developer setting to have it randomize when you join.
Let’s say you want to set a static DHCP ip from your router. The only way to do so (from the router, I’m not talking from the phone), is by assigning an IP to a MAC address.
If the address is randomised per connection, affecting a static DHCP ip would be impossible.
Another thing a router often has is some sort of dhcp memory. It remembers the ip it gave to a certain MAC address for some time, then when the device connects back, it assigns the same IP it had before.
So if the ip changes each time either the MAC address changes each time (not sure it’s default), or the router has no memory.
for a device without inbound connectors and no ip based lan firewall rules, which applies to most phones, random per connection macs seem like a pretty good default for privacy.
some networks doing “unusual” things like hotel wifi limiting you to few devices (implemented by mac counting) may be thrown off though.
I didn’t say there were no use cases for this, but the average phone user will not need it. someone using samba on their phone would likely be capable of switching the network config to not randomize every time.
That’s the point though. The address is randomized per connection specifically so the device can’t be identified. It’s to prevent tracking, blocking, or assigning, anything based on mac address without the device owners knowledge. Every time your phone connects the network has to treat it like a new device. If it was randomized per network that would defeat the point.
I personally can’t think of any reason you would need a static IP on your phone but if you did then you should know enough to know how to turn off the randomized mac address. You can even change the setting per network so if you need a static ip at home then you just set your phone to use a static mac address on your home network and continue using a randomized one on every other network.
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?
If you enable Developer Options, there is a setting under Networking called “Wi-Fi non-persistent MAC randomization” that randomizes the MAC per connection for networks that have randomization enabled.
