Configuring USB Modems
The LAN-Cell 3 auto-recognizes and configures itself for over 100 different USB
modem models on dozens of cellular service provider networks. Please refer to the
LAN-Cell 3 Firmware Release Notes for the list of currently supported modems.
The USB modem may need to be activated with a cellular service provider before it
can used in the LAN-Cell 3 Follow the service provider or modem manufacturer’s
instructions for activating, testing, and updating the firmware on the USB modem
before attempting to use it in the LAN-Cell 3.
Proxicast recommends implementing the WAN Fail-Over Connectivity Check found
on the Setup > WAN Advanced screen for maximum 4G/3G connection reliability.
By default, this feature is enabled and configured to ping a high-availability server.
Some modems require cellular service provider specific settings to be entered on
the LAN-Cell 3’s Setup > WAN screen. If the USB modem and carrier settings are
not auto-detected, obtain the following information from the service provider:
Parameter
Your Cellular Carrier’s Settings
APN
†
Authentication Type
Username / Password
ISP Access #
Φ
#777 for CDMA, *99# for GSM
PIN Code
‡
† APN applies only to GSM carriers. Many GSM carriers operate different APNs for different types of data service plans.
Φ The LAN-Cell does not use the phone number assigned to the USB modem. That number is used only by the provider.
‡ The 4 digit PIN code field is required only if the SIM/RUIM is has been locked.
Once the LAN-Cell is functioning satisfactorily, Proxicast strongly
recommends backing up the device configuration to a PC.

External Antenna Connections
Most USB modems include one or more external antenna ports. Consult the USB
modem documentation for the location of these ports. For modems without external
antenna ports, use a USB extension cable to relocate the modem for improved
signal strength if necessary.
Use a LAN-Cell “pigtail” consisting of the connector for the USB modem and a
standard SMA female jack. Install the SMA connector in one of the “D” shaped
SMA mounting holes in the Multi-Function Mounting Base (Figure 8).
Warning: The external antenna ports on USB modems are very fragile.
Use extreme care when inserting and removing antenna pigtails.
