Ethernet WAN Settings

Internet Connection Mode
The gateway can access the Internet through the mobile broadband network or through an
Ethernet WAN connection with a cable modem or DSL modem. The WAN Ethernet connection
can be through a corporate network, a cable modem, or a DSL modem. You can specify how
the gateway manages Internet connections. The gateway has three Internet connection modes:

Fixed-line. The gateway uses only the Ethernet WAN connection for Internet access.
Dual WAN Configuration
When the dual WAN setting is selected, the gateway monitors network connectivity over
Ethernet. If the Ethernet WAN connectivity is disrupted, the gateway uses the mobile broadband
connection. When the Ethernet WAN connection is restored, the gateway automatically
switches back to using the Ethernet WAN connection.

You can configure the gateway to detect network connectivity over Ethernet in one of two ways:
●
Periodically ping a specified IP address.
●
Periodically send DNS requests to a DNS server.
You can also configure how many consecutive failures (DNS query or ping) determine a
network connection failure and how often to query DNS server or ping. These settings affect the
time it takes to fail over and fall back. NETGEAR recommends using at least three intervals to
indicate a failure.
network connection failure and how often to query DNS server or ping. These settings affect the
time it takes to fail over and fall back. NETGEAR recommends using at least three intervals to
indicate a failure.
For example, if the ping method is selected, the gateway pings the specified IP address four
times during each try. So if the interval is set as 10 and the retry is set as 3, the gateway sends
12 pings (4 pings in each try every 10 seconds).

12 pings (4 pings in each try every 10 seconds).
For a failover scenario, if the Ethernet cable is disconnected, the gateway detects a physical
connection failure within 15 seconds and does not wait for specified number of consecutive
failures to switch to mobile Internet. During fallback, the gateway requires the physical
connection and a successful ping or DNS query to determine Ethernet connection is
operational.

Note: During failover, it may take a few seconds for LAN clients to resume Internet use.
Note: If you reboot your gateway, you must have the Ethernet WAN connection in place for this
feature to work correctly. You cannot have your cable unplugged.
