How to fix the abnormal state of a cellular module in a Peplink modem (apply FW version 8.5.0s059 build 5185)

Updated over a month ago

Scope

This guide provides instructions for upgrading device firmware for your Peplink device(s) and Cellular Module firmware to resolve the Cellular Modem issue. When the Cellular Module is faulty, SIMs are not detected in the modem and/or the modem will not connect to a cellular network.

Prerequisites

Required Steps

Two steps are required for a successful upgrade:

  1. Update of Device firmware to modem (v8.5.0s059 build 5185)

  2. Update of Cellular Modem Module Firmware (v1.14.22, v1.14.24)

Workflow

There are two possible options for getting connectivity to a modem.

  1. Remotely using a Web Browser (assuming device is already communicating).

  2. Direct Connection with an Ethernet cable between a Laptop and the Modem.

The workflow diagram will guide you through which option and steps are required when attempting to access a modem.

Step 1: Device Firmware Installation

  1. Option 1: Attempt to connect to a modem using a web browser. In the URL line enter the IP address of the modem followed by :8080.

    1. Example: 11.22.33.44:8080

  2. If you see the modem login page, enter the username and password

  3. When Modem Dashboard opens, you can go to step 7 below.

    1. If you did not access the modem user interface, continue with step 4.

  4. Option 2: Connect Laptop to the LAN port on modem with Ethernet cable.

  5. Open a web browser. Enter 192.168.50.1:8080 into the browser.

  6. Login into the Web UI using the following information:

    Username: admin

    Password: Ch3mtr34t

  7. From the menu, select System.

  8. From the left menu bar, select InControl.

  9. From Controller Management Settings, select InControl from the drop down.

  10. Click Save button and then Apply Changes / Confirm

    ATTENTION: At this point navigate to the Status menu item in the top button bar. If you see a heading under System Information which states “In Control Managed Configuration” , you can STOP. The device will automatically update the FW on its own. However, if you do not see that heading, you must continue with Step 11 (Firmware) below to complete the update.

  11. From the left menu bar, select Firmware

  12. From “Manual Firmware Upgrade”, select Choose File and locate the .bin file downloaded from the link provided in Prerequisites and Select Manual Upgrade

  13. The router will now update the firmware version to 8.5.0s059 build 5185

  14. Be advised to click the download link in Firmware Upgrade message box in case of unintended failure

  15. Select OK on the firmware upgrade confirmation window

    NOTE: The upgrade process will take 5-7 minutes. Do not navigate away or disconnect from the router during this time

  16. The firmware update window will appear to indicate the status of the upgrade

    *NOTE* The router will reboot during the firmware upgrade which may cause the client device to lose connectivity. If the firmware installation appears to freeze, check to ensure you are still connected to the Peplink’s network and reconnect if necessary

  17. Once the firmware update has completed, the new firmware version will be viewable from the main DASHBOARD

  18. With 8.5.0s59 build 5185 loaded, check that the cellular module is detecting both SIM cards by selecting Dashboard. View the cellular connection in the WAN Connection Status section

    Note: it may take some time to obtain a cellular connection. Once, you have obtained a cellular connection, move on to the Updating the cellular module’s firmware section

STEP 1 COMPLETE

Step 2: Updating the Cellular Module's firmware

To update the cellular firmware version, you must modify the Peplink modem’s Web UI URL.

  1. From an active modem connection, Copy the URL link and paste it into another tab.

  2. Modify the link by replacing index.cgi with support.cgi and load the page

  3. The following webpage will open

  4. To update the cellular firmware, select the Check for update button in the
    Cellular module firmware update section

  5. A new menu will be displayed

  6. Select the radio button on the left side of the screen then select the Update button

    Please note that the current Cellular Modem Module firmware version is 01.14.22.00(AT&T,GENERIC,T-MOBILE), 01.14.24.00(VERIZON).

    *NOTE* All cellular data sessions will be disconnected during update. Each module update takes about 5 to 20 minutes to complete. Please do not power off the device until completion

  7. After the update is complete, verify that the current firmware version has been applied by selecting the Check for update button again and view the current firmware version. Navigation back to the support.cgi link may be necessary as the original connection will drop

    STEP 2 COMPLETE
