Problem Resolution
Gobi 2000/3000 Verizon Provisioning
Overview
This document is intended for Digi TransPort units with Gobi modules using the Verizon network.  The purpose is to quickly walk you through running the Gobi Carrier Wizard, and how to provision the device for Verizon networks.  It also highlights items to look at and how to test the unit
 
Assumptions
This guide assumes that you have a PC that is able to reach the TransPort through the Ethernet interface to gain access to the Web User Interface (WebUI) for configuration purposes.
 
Running the Gobi Carrier Wizard
The first thing that will need to do be done is to run the Gobi Carrier Wizard to enable the device for Verizon. The following steps will guide you through this process:
 
1) Log into the WebUI through the Ethernet interface. (Default IP address is 192.168.1.1)
 
2) Once in the WebUI, click on Wizards on the upper-left hand side, as shown in the screenshot below:
User-added image

3) Click on the GOBI Carrier Wizard, and then click Next, as shown in the screenshot below:
User-added image

4) Choose Verizon, and click Next, as shown below:
User-added image

5) On the next page, you will see a line that says “Save configuration changes here”, with the “here” being blue in color and underlined. Click the ‘here’ link and then click Save on the next screen. Reboot the device after saving.
 
6) After the device reboots, log back into the WebUI.
 
7) Navigate to Configuration > Network > Interfaces > Mobile > CDMA Provisioning.
 
8) Under the section titled Automatic Provisioning, click the Start button. DO NOT fill in any of the 3 parameters unless told to by Digi.  DO NOT fill out anything under Manual Provisioning.

9) This process will take ~2 minutes to complete. Once the process completes, a message at the top of the page will indicate if it has either been successful or failed to provision. If successful, click the Reboot link and reboot the device.  If failed, try provisioning again.  Please email Digi Technical Support with the debug.txt file (please see “When contacting Digi Technical Support” below) if the failure continues. 
 
Once the unit is provisioned, it could take another minute or so before it establishes an IP address.
 

Indicators, WebUI
 
LED Displays
 
For the WR41 & WR44
W-WAN NET
Will illuminate steady if the unit is able to log on to the Verizon mobile network.

W-WAN SIM
This LED should not light up since you do not a SIM for a Verizon account.

W-WAN DAT
Represents data passing to and from the network.

Signal Strength
Here is a guide for the signal strength:
  • -113 dBm or less (0 LED) -> effectively no signal
  • -112 dBm to –87 dBm (1 LED) -> weak signal
  • -86 dBm to –71 dBm (2 LEDs) -> medium strength signal
  • -70 dBm or greater (3 LEDs) -> strong signal
The minimum recommended strength indication is 2 LEDs. If you have no or 1 LEDs lit, it is recommended that you fit an external antenna to the unit.
 
For the WR21
Service
Illuminates steady when there is a network connection to the WWAN interface and flashes when data is transmitted or received.

WWAN
Flashes to show which network mode the unit is operating in:
  • Off - no service
  • 1 blink - GPRS mode
  • 2 blinks - EDGE mode
  • 3 blinks - UMTS mode
  • 4 blinks - HSDPA mode
  • 5 blinks - HSUPA mode
  • On steady - CDMA mode
Signal Strength
Here is a guide for the signal strength:
  • -113 dBm or less (0 LED) -> effectively no signal
  • -112 dBm to –87 dBm (1 LED) -> weak signal
  • -86 dBm to –71 dBm (2 LEDs) -> medium strength signal
  • -70 dBm or greater (3 LEDs) -> strong signal
The minimum recommended strength indication is 2 LEDs. If you have no or 1 LEDs lit, it is recommended that you fit an external antenna to the unit.

Note: The newest information is on top of this file.
 
Testing
Once you have set up the mobile settings on your unit and you see a mobile IP address, there are a couple of quick tests you can do to ensure your device is working.
 
Ping Test
 
Go to Administration > Execute a command.  Enter ping followed by a hostname or IP address and then click Execute.
 
For example:  ping www.digi.com
  1. If the result is good, you will see the response time as well as Success of 100%.
  2. If the result says ‘unable to resolve <hostname>’, then something is wrong with the DNS primary and secondary addresses.  Please look under Management > Connections > PPP Connections > PPP 1 – W-WAN to verify you have a primary and secondary DNS address.
  3. You should also try to ping a working, public IP address instead of a hostname.  For example: ping 66.77.174.59
  4. If this result is good (see above for a good response), then again there is something wrong with the primary and secondary DNS addresses.
  5. If the result fails, you will see ‘no response from <ip address>’.  Please verify you have a mobile IP address by going to Management > Connections > PPP Connections > PPP 1 – W-WAN.
  6. If you do not have an IP address, please email Digi Technical Support with the debug.txt file (please see “When contacting Digi Technical Support” below).
  7. If you do have a mobile IP address, but cannot ping to a valid, public IP address, please verify with the provider if you have a public or private mobile IP address.
 
Accessing the Internet
 
If you have a laptop or computer directly connected to your Transport, you can try opening a browser and accessing the Internet.
 
NOTE: In order for this step to be a valid test, you must ensure you do not have another source to the Internet, such as being connected to your company’s network either via Ethernet or over Wi-Fi.
 
If this fails, please verify the Ping Test still passes.  If the ping test passes and you cannot access the Internet, please email Digi Technical Support with the debug.txt file (please see “When contacting Digi Technical Support” below).
 
Accessing the Transport Remotely
 
If you have a Mobile Terminated account, you should be able to access the Transport remotely.  Find a laptop or PC that has Internet access (not connected to the Transport), open a browser, and specify the mobile IP address of the Transport.
 
If this fails, please verify that you have Web Server enabled (Configuration > Network > Network Services).  Having IP Forwarding (Configuration > Network > IP Routing/Forwarding > IP Port Forwarding/Static NAT Mapping) or IP Passthrough (Configuration > Network > IP Passthrough) enabled could affect these results as well.  Otherwise, if you cannot access your Transport remotely, the issue could be that you have a mobile originated account or a private account.  You should check this with your provider.
 
Mobile Originated vs. Mobile Terminated
 
Mobile Origination – Allows for outbound data to pass through the Digi and receive responses from the data request, but it does not allow for data originating from the Internet to pass through the Digi or to devices beyond it.
 
Mobile Termination – Allows for 2-way communication of data, where data from the Internet can reach the Digi and beyond, and data from the Digi can go to the Internet.
 

Troubleshooting
Ensure you are on the latest firmware
Updating your firmware may resolve your issue as well as enhancements to both your Transport and traces for troubleshooting.
  1. To check your firmware, go to Administration > System Information and note your Firmware Version
  2. Compare the firmware version to our latest release by going to www.digi.com > Support > Firmware Updates
  3. Enter your Transport Model (i.e. WR21) in the field and then click on your particular model
  4. It should bring you to a page for your product.    Choose the fimrware for the type of upgrade you will performing, either via FTP (WebUI) or FlashWriter, from the options on the page and save the file to your PC.
