Fail-over Settings
If the LAN1/WAN port is configured in WAN mode, you can select WAN port or
WWAN port to access the Internet connection.
Figure 18: WAN – Fail-over Settings
When both WAN and WWAN connections are available, the NHD1W uses the WAN
connection as the primary connection and the WWAN connection as the backup
connection. In this case you can select one of the four connection types:
Connection Type
Description
WAN
The failover function is disabled and the NHD1W will use WAN
connection only.
WWAN
The NHD1W will use WWAN connection only. AirCard mobile
hotspot will be required for Internet connection.
WWAN Failover if
WAN link down
The NHD1W uses WAN connection as a primary connection and
WWAN connection as a backup connection. When the WAN
connection is physically disconnected, the NHD1W will start using
WWAN connection for Internet access.
WWAN Failover with
WAN ping
The NHD1W uses WAN connection as a primary connection and
WWAN connection as a backup connection. The NHD1W will
periodically ping the assigned servers. When none of the servers
respond to the ping message, the NHD1W will switch to use WWAN
connection for Internet access.
The periodic ping settings can be configured by opening the System
Monitor page under Services menu.
Click Save to apply the settings.
Air Card and Dock(EUT)
EUT supports 2 modes:
1. EUT WLAN function can direct network transmission to other client devices.
2. a. When hotspot router plugged in, EUT WLAN function is disabled. The router
would share the WWAN capability to other client devices, through WLAN
function on the plugged-in router.
b. When the router plugged in, the WWAN RF signal would be directed to
external antenna on EUT, to enhance WWAN receiving capability.
At this moment, the WWAN RF signal would not transmit/receive through
original antenna on the router.
