Connect a Computer, Switch, Hub, Router, or WiFi Router
to the Modem
By default, the modem functions in Router mode with the DHCP server enabled and IP pass-through (IPPT)
disabled. This means that you can connect multiple devices to the modem, for example, through an Ethernet
switch or hub, and that each device can receive an IP address from the modem.
If you want to connect a router or WiFi router to the modem, change the operation mode of the modem to
Bridge mode, in which IP pass-through (IPPT) is enabled and only a single device can be connected to the
Internet through the modem. (The single device that is connected to the modem is the router or WiFi router,
but depending on the capabilities of the router or WiFi router, you can connect multiple devices to the router
or WiFi router.)
If you want to connect a computer only to the modem, the modem can function either in Router mode or in
Bridge mode.
For information about changing the operation mode of the modem, see
on page 26.
