Mobile wifi can't open, because there is something wrong with the modem affected, then what kind of relationship between the two, how impact, strives for the bosses science?

Personal understanding:
Wifi and modem is not the same as
Wifi contains 2.4 G and 5 G spectrum
Modem is a 3 g, 4 g, 5 g
Wifi when not card, as long as there is a hot spot is also can go online
Modem without card, is not the call, not on the net, a different channel
