Change the Physical WAN Connection Preference
The modem router can autodetect the type of WAN connection. However, you can also set the WAN connection
preference manually to either the DSL port or the Ethernet WAN port.
The modem router does not support load balancing over DSL and Ethernet WAN interfaces.
Only
one
WAN interface (either the DLS port or the Ethernet WAN port) can be active at any
time.
Note
To change the WAN connection preference:
1.
Launch a web browser from a computer or WiFi device that is connected to the network.
2.
Enter
.
A login window opens.
3.
Enter the modem router user name and password.
The user name is
admin
.The default password is
password
.The user name and password are case-sensitive.
The BASIC Home page displays.
4.
Select
ADVANCED > Setup > WAN Setup
.
The WAN Setup page displays.
5.
From the
WAN Preference
menu, select one of the following options:
•
Must use DSL WAN
. The modem router uses the DSL port for a DSL WAN connection. The Internet port is
shut down.
•
Must use Ethernet WAN
. The modem router uses the Internet port for an Ethernet WAN connection. The
DSL port is shut down.
6.
Click the
Apply
button.
Your settings are saved.
Enable Bridge Mode for IPTV Devices
Some devices, such as an IPTV, cannot function behind the modem router’s network address translation (NAT)
service or firewall. Based on what your Internet service provider (ISP) requires, for the device to connect to the ISP’s
network directly, you can enable the bridge between the device and the modem router’s virtual IPTV interface. In
bridge mode, by default, the LAN 4 port on the back panel of the modem router is bound to the virtual IPTV interface.
In addition to connecting an IPTV device to the LAN 4 port, you can connect an IPTV device to the LAN 3 port and
another one to the LAN 2 port. That is, the modem router can support up to three IPTV devices. The LAN 1 port is
reserved for a wired Internet connection. Do not connect an IPTV device to the LAN 1 port.
For information about enabling and configuring the virtual IPTV interface, see one of the following sections:

Enable and Configure a VLAN
A network of computers and devices can behave as if they were connected to the same network even though they
might actually be physically on different segments of a LAN. Virtual LANs (VLANs) are configured through software
rather than hardware, which makes them very flexible.

If you enable a VLAN and if the network devices (hubs and switches) on your LAN support the VLAN (802.1Q)
standard, the VLAN ID is associated with all traffic coming from the modem router.
If you are subscribed to IPTV service, the modem router might require VLAN tags to distinguish between the Internet
traffic and the IPTV traffic.
For information about enabling and configuring the virtual IPTV interface, see one of the following sections:
•
Manually Set Up an ADSL Internet Connection
on page 50
•
Manually Set Up a VDSL Internet Connection
on page 59
•
Manually Set Up a Cable or Fiber Internet Connection
on page 68
If your ISP provides directions for how to set up VLANs for IPTV and Internet service, follow
those directions.
Note
To enable and configure a VLAN for the virtual Internet interface and another VLAN for the virtual
IPTV interface:
1.
Launch a web browser from a computer or WiFi device that is connected to the network.
2.
Enter
.
A login window opens.
3.
Enter the modem router user name and password.
The user name is
