Question / Issue
Using the Netgear AirCard 340U (AT&T Beam) USB modem in the LAN-Cell 3 or PocketPORT

Answer / Solution

By default, the 340U functions as a NAT Router and not a pass-through modem.  Perform the following steps with the 340U too enable IP Pass-Through and Auto-Connect Modes before using it with the LAN-Cell or PocketPORT routers.

  • With the 340U modem connected to a PC, install and run the AT&T All Access communications software.  This application should install directly from the 340U modem when inserted into a Windows PC.

  • With the 340U not connected to the AT&T network, select the Settings icon to open the Settings screen.

  • Select the Mobile Connection menu, then press the Control + Shift + M keys simultaneously to expose the hidden Mobile Profiles button.

  • Click the Mobile Profiles button and create/dit a mobile profile that corresponds to the APN to which your account is assigned by AT&T (e.g. "broadband", "internet", "I2GOLD", etc.).  Contact AT&T Customer Service if you do not have this information.

  • Select the correct profile and click the back arrow to return to the Mobile Connection menu.  Close the Settings window. 
  • Return to the All Access Home screen and confirm that you can make a successful connection to AT&T and that your PC is receiving the IP address expected. 
  • Open the Settings Screen again and select the Update menu. 
  • If the 340U detects that a newer firmware version is available, download and install the update (the available version may differ from the sample screen above).

  • Close the All Access application. 
NOTE: The Netgear Utilities mentioned below do not run under Windows 10

  • If you have a public / static IP address from AT&T and are using an APN other than "broadband" (such as "I2GOLD"), then download and launch the AC340U_ip_pass_through_enable.exe utility from the link below.  This step is not required when using the "broadband" APN since it always performs NAT and issues private IP addresses.  Note - this utility may not run correctly under Windows 10.

  • If the firmware loaded on the 340U is NTG9X15C_01.13.12.13 r18963 or newer, then you must also download and run the Netgear AC340U_AutoConnect_Enable.exe utility.

  • Remove the 340U modem from the PC.  It is ready to use in the LAN-Cell or PocketPORT.

 

NOTE #1: Enabling IP Pass-Through Mode cannot be undone.  The 340U will continue to operate in this mode even when used in devices other than the LAN-Cell or PocketPORT (e.g. Windows/MAC/Linux PCs).

NOTE #2: AutoConnect Mode may be disabled in order to change settings using the All Access application. Download and run the utility below before launching All Access.

NOTE #3: Due to USB bus timing issues in some AirCard 340U firmware versions, a USB adapter (ACC-USB-003) is required with the LAN-Cell or PocketPORT to ensure reliable detection of the 340U modem.
