Not all Wi-Fi networks are created equal. Wi-Fi
access points can function in either “ad-hoc” or “infrastructure” mode, and
many WI-Fi-enabled devices can only connect to infrastructure-mode networks,
not ad-hoc ones.
Wi-Fi networks in infrastructure mode are
generally created by Wi-Fi routers, while ad-hoc networks are usually
short-lived networks created by a laptop or other device. But it isn’t always
so simple.
