You can switch between interfaces after the modem is installed
and configured, but before doing so, you need to understand
the interface hierarchy.
If you switch from a serial interface to any other interface, the
serial interface is disabled. If you switch from USB to either a
Ethernet or wireless access point, the USB connection is lost. If
you switch from Ethernet to wireless access point (MP modem
only), the Ethernet connection is disabled.
Watcher is available for all network interfaces except wireless
access point.
