Unfortunately, this isn't compatible with a bunch of popular wireless cards, mostly from Realtek.

Realtek and Ubuntu - I have spent four years trying to get my wifi to work. Being tracked would be a bonus, the built in wifi on my Lenovo laptop is deaf to the world and will never get as far as MAC spoofing.

Can you show me where changing your MAC address is illegal?

It's not illegal, it can be detected and then used against you in an indictment. It's like saying you dislike someone, they go missing, and the prosecutor mentions what you said.

> and the prosecutor mentions what you said.

And then what? You're under further suspicion? If you're innocent, that shouldn't be your concern. But all you gotta do is STFU. Don't talk to the police either way.

What you said shouldn't be enough proof except in a banana republic.

If you were always spoofing your MAC address however, then you can use that as your defense.

Your argument is akin to it being suspicious that you use Tor. As if that means your computer should be seized because you might have WMDs. Tor usage might make you suspicious only if other credible factors exist.

The MAC could remain unchanged for established connections while changing for new connection offers.

What does that accomplish?

It accomplishes what changing it in the first place is intended to accomplish - anonymity. Changing for established connections offers no benefits.

What effect does being a banana republic have on this?

It’s worth noting that iOS has randomized MAC addresses in WiFi probes since iOS 8.[1] As far as I know your real MAC address is exposed upon connection. I’m curious to what extent other vendors have implemented this strategy. [1] https://arstechnica.com/gadgets/2014/06/ios8-to-stymie-track...

Unfortunately the iOS support is a sham. I tested myself, and the rumors that iOS does not randomize MACs turns out to be true. Not only does it not simply change over time, it doesn't even change when you restart the device. I walked around for a week, and my MAC never changed.

Apparently, if it ever works at all, you have to run settings that nobody uses - including, iirc, not being connected to a cell tower. I used to spread the same FUD of "iOS does this!", but the truth is it's a lie.

The law cares about intent. Changing your Mac address, or wearing a fake beard, are both fine. Changing your Mac address to trick a Wi-Fi hotspot which gives out one hour free per device per day, or using a fake beard to trick a shop keeper into letting you get "one free bagel per person" twice, is a crime.

This is what I was getting at.

So... this post is about Ubuntu, but if we're going down that road: https://medium.com/@philipn/want-to-see-something-crazy-open...

Are there any demos for this still available?

so exploits are crimes?

Damn, I didn't know about these. Do you know what it is that makes them incompatible? And is there a list of cards you can avoid?
