Modem Settings Not all modems will have all of the options shown below; the available options are specific to the modem type.
On Demand: When this mode is selected a connection to the Internet is made as needed. When this mode is not selected a connection to the
Internet is always maintained.
IP WAN Subnet Filter: This feature will filter out any packets going to the modem that do not match the network (address and netmask).
Aggressive Reset: When Aggressive Reset is enabled the system will attempt to maintain a good modem connection. If the Internet has been
unreachable for a period of time, a reset of the modem will occur in attempt to re-establish the connection.
Automatically check for new firmware: (Default: selected) The modem will automatically check for firmware updates by default.
Enable Aux Antenna: (Default: selected) Enable or disable the modem's auxiliary diversity antenna. This should normally be left enabled.
GPS Signal Source: Select the antenna to be used for receiving GPS coordinates. Some products support a dedicated GPS antenna, while others
use the auxiliary diversity antenna only (and some products support both).
Enable eHRPD: (Default: selected) Enable or disable the modem's ability to connect via eHRPD (enhanced High Rate Packet Data) when connecting
to a 3G EVDO network on Sprint. eHRPD routes EVDO traffic through the LTE systems, enabling easy transitions between LTE and EVDO. In rare
cases it may make sense to bypass the LTE core, so this field allows you to disable eHRPD.
Modem Connection Mode: Specify how the modem should connect to the network. Not all options are available for all modems; this will default
to Auto if an incompatible mode is selected.
• Auto (all modes): Let the modem decide which network to use.
• Auto 3G (3G or less): Let the modem decide which 2G or 3G network to use. Do not attempt to connect to LTE.
• Force LTE: Connect to LTE only and do not attempt to connect to 3G or WiMAX.
• Force WiMAX: Connect to WiMAX only and do not attempt to connect tot 3G or LTE.
• Force 3G (EVDO, UMTS, HSPA): Connect to 3G network only.
• Force 2G (1xRTT, EDGE, GPRS): Connect to 2G network only.
Network Selection Mode: Wireless carriers are assigned unique network identifying codes known as PLMN (Public Land Mobile Network). To
manually select a particular carrier, select the Manual radio button and enter the network PLMN. Choose from the following options:
• None/No Change
• Auto: Selected by default
• Home only
• Manual: Input the PLMN code
Functional Mode: Selects the functional mode of the modem. IPPT (IP passthrough) mode causes the modem to act as a transport, passing
Internet data and IP address information between the modem and the Internet directly. NAT mode causes the modem to NAT the IP address
information. Consequently, IPPT mode does not allow user access to the modem web UI and NAT mode does allow user access to the modem
web UI.
• None/No Change
• IPPT
• NAT
Network-Initiated Alerts: This field controls whether the Sprint network can disconnect the modem to apply updates, such as for PRL, modem
firmware, or configuration events. These activities do not change any router settings, but the modem connection may be unavailable for periods
of time while these updates occur. The modem may also require a reset after a modem firmware update is complete.
• Disabled: The request to update will be refused.
