e. For Use DNS:
n
n
n
The default setting is When primary default route.
f. SIM failover is enabled by default, which means that the modem will automatically fail
over from the active SIM to the next available SIM when the active SIM fails to connect. If
enabled:
i. For Connection attempts before SIM failover, type the number of times that the
device should attempt to connect to the active SIM before failing over to the next
available SIM.
ii. For SIM failover alternative, configure how SIM failover will function if automatic SIM
switching is unavailable:
9. For APN list and APN list only, the TX54 device uses a preconfigured list of Access Point
Names (APNs) when attempting to connect to a cellular carrier for the first time. After the
device has successfully connected, it will remember the correct APN. As a result, it is generally
not necessary to configure APNs. See
and instructions for setting an APN.
10. (Optional) To configure the IP address of a custom gateway or a custom netmask:
a. Click Custom gateway to expand.
b. Click Enable.
c. For Gateway/Netmask, enter the IP address and netmask of the custom gateway. To
override only the gateway netmask, but not the gateway IP address, use all zeros for the
IP address. For example, 0.0.0.0./32 will use the network-provided gateway, but with a
/32 netmask.
11. Optional IPv4 configuration items:
a. Click IPv4 to expand.
b. IPv4 support is Enabled by default. Click to disable.
c. Set the Metric.
See Configure WAN/WWAN priority and default route metrics
metrics.
d. For Weight, type the relative weight for default routes associated with this interface. For
multiple active interfaces with the same metric, Weight is used to load balance traffic to
the interfaces.
