Yes thanks. The point is those click-thru landing pages work by temporarily whitelisting your MAC, which means they have a list of MACs somewhere. The MAC information needed by ordinary networks is ephemeral.
- colanderman 10y agoEven without click-throughs. Comcast Business routers keep a log of every MAC that's ever connected wirelessly. Granted I think it's a bug as it causes the MAC whitelisting page to take like a minute to load. Even my Mikrotik at home logs MACs by default. The log is small and not persisted, but log entries definitely stick around a few days. Don't count on your MAC not being logged.

- geofft 10y agoDHCP also works by recording your MAC (so that you can renew your IP, and another computer can't). Most DHCP servers write their lease files to disk. Most also log to disk. I wouldn't consider the absence of a captive portal to be a strong signal.
