16. 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.
17. (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

netmask.
