After the interface was brought up with the command wlan0 up, the script proﬁle-select tries to match the as-

signed IP number against a list of possible IP numbers to select the appropriate network proﬁle. This proﬁle is

the installed by copying conﬁguration ﬁles and by starting or stopping system services. After the interface was

brought down, the script proﬁle-deselect reverts to a special default proﬁle called ofﬂine,which does not map to

anetwork scheme.
