Then I do it again next week after a reboot. What information would a nearby shop or a passive malicious hacker be able to find about my device? Does my device send out identifying information before joining, like a MAC address? Is this persistent, or randomized?\n\nI intentionally haven’t specified a distro, so if something only applies to some network managers, give some details.\n\nBonus points: what about Android phones?",
