I remember that time before I had a smart phone, but while I had a laptop & before there was security concerns to bother password protecting WiFi access points. I used to stop by roadside hotels/motels & whip out the laptop to do any on-the-go research since it was free & I didn’t yet have a taste for coffee (or the money) to want to stop by a café. The other highlight was using SMS/MSS via email & doing $NUMBER@verzion.net or whatever the address was. The SMS rates were high & I was always carrying my laptop & usually could nab open WiFi
somewhere.

Other WiFi-related anecdote is my Fujifilm camera (RIP capacitor) chose to do its app communications between camera & smart phone over WiFi. I’m assuming this was a range thing, but it was interesting being in the wilderness & joining a LAN to get remote control.
