Exactly, and let’s give them the benefit of the doubt since we don’t know. The librarian or assistant helping OP probably just doesn’t know much about the IT stuff other than how to help people get on the wifi. And it is entirely possible that they’re NEVER seen anyone even try the port before, that’s not common at all. Actually managing the IT infrastructure at that level is almost surely NOT part of their job.

WiFi has been included in essentially everything for over a decade. I mean even ignoring laptops having Wifi way before mobile devices, even going back to the origin of smartphones for the masses, the original iPhone had Wifi back in 2007, that’s 17 years ago.
