WIRELESS WAN CONNECTIVITY
The CradlePoint CBA750B mobile broadband series adapters enable easy-to-install wireless WAN connectivity in fixed-
business locations. For distributed enterprises like branch offices, retail stores, restaurants, and small businesses, the
CBA750B provides 3G/4G wireless network connectivity to keep your business up and running.

For temporary networks – or when wired connections are impractical – the CBA750B can serve as a primary-connect
device, converting mobile broadband to Ethernet for point-of-sale tools, digital signs, and kiosks.
KEY FEATURES

Modem Signal Strength: The bar LEDs indicate the signal strength from the active 3G/4G modem (CradlePoint
business-grade modem or USB/ExpressCard modem). Pushing this button toggles the display on and off. The signal
strength is shown for 10 seconds if the modem does not support concurrent data connection and signal strength
measurement. A blinking LED indicates "bar.
LAN Port: The CBA750B has one Ethernet port for a local network connection. Use this for connectivity and also for
Power-over-Ethernet (optional).
Power On/Off:
•I = On
•O = Off
DC Power Port: Attach the included power supply.
Reset: Return your CBA750B to factory default settings by pressing and holding the Reset button. This button is
recessed, so it requires a pointed object such as a paper clip to press. Press and hold for 10 seconds to initiate reset. This
erases configuration changes and resets the administrator password to the Default Password found on the product label.
USB/ExpressCard Modem Ports: The CBA750B has two USB 2.0 ports and one ExpressCard port.
Router/Passthrough Switch:
•I = Passthrough mode – Forces complete IP passthrough configuration.
•O = Router mode – Allows normal configuration options for the router.
The CBA750B ships with the Router/Passthrough Switch set to IP passthrough mode. In IP passthrough mode, all
of the following settings are pushed to the router:
•Load balance is disabled; the highest priority WAN device is used.
•The Routing Mode is set to IP Passthrough. (Network Settings !Local Networks in the “Local Network Editor”
under “IP Settings”)
•The Subnet Selection Mode is set to “Automatically Create Subnet”. (Network Settings !Local Networks in the
“Local Network Editor” under “IP Settings” – shows when IP Passthrough is set as the Routing Mode)

3.3 Common Problems
This section contains some of the most common issues faced by users of the CBA750B.
Please visit CradlePoint Knowledge Base at http://knowledgebase.cradlepoint.com/ for more help and answers to your
other questions.
3.3.1 You Cannot Connect to the Internet with a CradlePoint business-grade modem
Make sure that you have an active data plan and that your modem has been activated. A wireless broadband data plan
must be added to your business-grade modem. Wireless broadband data plans are available from wireless carriers such
as Verizon, AT&T, and Sprint. A new line of service can be added or a data plan can be transferred from an existing
account. You will need the ESN number (or SIM/IMEI number depending on your carrier plan) from the product label on
your modem to add or transfer a line of service.
After adding a data plan to the modem, you may need to activate the modem:
1. Log in to the CBA750B administration pages (see Accessing the Administration Pages).
2. Select Internet from the top navigation bar and Modem Settings from the dropdown menu (Internet !Modem
Settings).
3. Find and select the CradlePoint modem.
4. Click Update/Activate.
5. Click Activate in the popup.
Finally, if you have an active data plan and you have already activated your modem, you may be out of range of your
service provider. Check your signal strength in the Internet section of the Dashboard (Status !Dashboard). If you have
a weak signal in your location, contact your service provider.
If you are still not online after activating the modem, call CradlePoint Technical Support for further assistance.

3.3.2 Your USB or ExpressCard Modem Does Not Work With the Router
•If your USB data or ExpressCard is not working with the router, check the list of supported devices at
http://www.cradlepoint.com/modems to ensure you are using a supported device and carrier. The device you are
using must be supported on the carrier network providing your cellular service or it’s considered an unsupported
device, even if it is supported on another carrier’s network.
•Sometimes a USB data modem needs to be updated or have other configurations set correctly in order to make a
connection through the router. If your USB Modem has not been updated recently, it is recommended that you do
so if it is having trouble connecting to the CBA750B. Insert your USB data modem into your PC and access the
Internet using the software provided by your cellular carrier. Follow the directions provided to complete the update.
Once you have updated your USB data modem, reconnect the cellular device to your CradlePoint router and
connect to the Internet.
•If you are using a WiMAX modem, you need to set the WiMAX Realm. This can be done in the administration
pages. Log in using the hostname “cp/”or IP address “http://192.168.0.1” in your browser. Go to Internet !
Connection Manager. In the WAN Interfaces section, select your modem and click “Edit.” Select the WiMAX
Settings tab and select/input your WiMAX Realm.
•Some wireless carriers provide more than one Access Point Name (APN) that a modem can connect to. If you wish
to specify the APN, this can be done on the administration pages. Log in using the hostname “cp/”or IP address
“http://192.168.0.1” in your browser. Go to Internet !Connection Manager. In the WAN Interfaces section,
select your modem and click “Edit.” Select the SIM/APN Settings tab. There is an Access Point Name field: Set
the APN and click Submit. Some APN examples are isp.cingular, ecp.tmobile.com, and vpn.com. The modem
must be removed and reinserted (or the router must be rebooted) for this change to take effect.
•If the above issues have been resolved and you can connect to the router but you cannot get Internet through it
using your modem, you may need to upgrade the router firmware. Use your computer (you may need to plug your
modem directly into your computer if you don’t have another way to access the Internet) to download the latest
firmware for the router at http://www.cradlepoint.com/firmware/CBA750B. Then log into the router administration

pages and manually upload the firmware. Go to System Settings !System Software and click on “Manual
Firmware Upload”.
If you are still unable to access the Internet after following the above directions, contact CradlePoint Technical Support for
further assistance.
