3 QUICKSTART
3.1 Setting Up Your Adapter
Connect Mobile Broadband Device –Plug a Business-Grade
Cradleptoint Modem, or USB or ExpressCard data modem into
the appropriate slot. The data modem should have an active data
plan.
Place CBA750 Adapter in best signal location –Use Modem
Signal Strength display to find the best location for the CBA750
Adapter. Use provided mounting hardware if desired.
Connect to a Router or Switch –Plug the Ethernet cable into a
routing device or switch.
Connect Power Supply –Connect the included power adapter if not using Power-over-Ethernet (PoE).
For most users, the CBA750 Adapter can be used without configuration. When needed, set the Configuration switch to
“O” to place the unit into configuration mode.
Configuration mode is used to set up user parameters, download new firmware, and enable cellular modem diagnostics
by accessing the administration page at http://192.168.0.1

3.3 Common Problems
This section contains a list of some of the most common issues faced by users of the CBA750.
Please visit CradlePoint Knowledgebase at http://knowledgebase.cradlepoint.com/ for more help and answers to your
other questions.
3.3.1 Your USB Modem or Phone Does Not Work With the Router
If your USB data modem or phone is not working with the router, check the list of supported devices to ensure you
are using a supported device and carrier. The device you‟re 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.
CradlePoint‟s supported device list changes regularly. We update our supported device list after a device is
certified and approved. If the device you have is NOT on the list, that means we do not support it at this time.
The SUPPORTED DEVICE list can be found at: cradlepoint.com/support/CBA750
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 CBA750. Simply insert your USB data modem into your PC and using the
software provided by your cellular carrier, access the Internet. 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 4G modem you need to set the WiMAX Realm. This can be done at the administrative page (login
to IP address http://192.168.0.1)and go to Modem → Settings. Under Modem Specific Settings use the WiMAX
Realm Select to select your carrier. Make sure you Save Settings.
Some wireless carriers provide multiple Access Point Names that a modem can connect to. If you wish to specify
an APN, this can be done at the administrative page (login to IP address http://192.168.0.1)and go to Modem →
Settings. Enter the APN and Save Settings. Some examples of APN are isp.cingular, ecp.tmobile.com and
vpn.com. This APN will be set in the first profile position (see Modem Diagnostics). The modem must be

CRADLEPOINT CBA750 | USER MANUAL Firmware ver. 1.9.0

removed and reinserted for this change to take affect (or the router rebooted). This APN is associated with the
modem in the interface referred to in the Modem Interface dropdown menu, so multiple APNs may be entered.
If the above issues have been resolved and you can connect to the router but not 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 (found at: www.cradlepoint.com/support/CBA750). Then login to the router admin page and manually
upload the firmware (directions can be found in this manual in section 6.2.2).
If you are still unable to access the Internet after following the above directions, contact CradlePoint Technical
Support for further assistance.

3.3.2 You are Connected to the Router but Cannot Connect to the Internet
The status LEDs of your router will give you an indication whether or not a proper connection is being made. See the LED
STATUS definitions below:
If the USB Data Modem LEDs are not illuminated, your modem is not connected and online. You may need to update
firmware. Refer to “Your USB Modem or Phone Does Not Work With The Router.”
If you are still not online after updating, call CradlePoint Technical Support for further assistance.
