  • A very important topic to cover in this article series is something we call security model of the router.

    Before getting to that, let's look at the user model. There are a few user models being used in the operating systems based on Linux. Please note that this definition is something to make our security model more understandable and help with further understanding of the securing process, it is not a formal definition as used in information science.

  • Router pwned

    You are about to read the first article in the series of articles about securing our routers. The series is tailored to our router devices, teaching and showing some general and specific principles and also describing possibilities and use cases. While some of the knowledge here is usable also outside of the router devices, you should keep in mind that we are focusing on our cellular routers running Conel OS 6.x here.

    This first article is a basic building block. We are going to describe the device and its basic characteristics and possibilities of accessing the device with an accent on security. Also, some basic use cases are to be touched here and the terminology used for the rest of the series established.

  • Be the first to comment
  • New version of firmware for our routers is available on Engineering Portal.

    Except the SR305 and SL302 which are destined for NAM market and thus a firmware change is a subject of certification, the 6.1.6 is available for majority of routers. Details of distributions can be found in the Firmware Distribution overview document.

    Just a quick repetition - you can always find the last firmware files available at Last firmware page and also directly linked to all appropriate Products.

    Using notifications on EP


    Written by Jan Otte on Wednesday 7 March 2018 in the category Default.

  • It has been some time since we implemented and enabled notifications on the Engineering Portal. The notifications are primarily meant as something extra for our distributors and partners (as it requires an account on EP), but for example the RSS can be used by anybody without an account needed - read on.

    The notification system we have is, thanks to the tagging system we use for all products and documents, quite unique however it could take some time getting used to. Also, we are still ...

    PCNs available on Engineering Portal from now on.

  • PCN is a name for a specific type of document. The abbreviation means Product Change Notification. It is a kind of a document we issue when there is important change in one or more products we are manufacturing.

    Not every change in a product requires a PCN. The documents are here so that we can communicate changes that may have impact on our partners, distributors and customers. Other changes, like, replacing one end-of-life component with equivalent one, may not be significant enough for creating a ...

    User Module FOTA Released!


    Written by Petr Hanuš on Tuesday 13 February 2018 in the category Default.

  • Be the first to comment
  • The Firmware Over-The-Air (FOTA) user module is an additional feature of Advantech routers. This module will assure the correct firmware for cellular module is chosen, downloaded and installed into the router automatically. Only the firmware of the cellular module is updated (not the firmware of the router).

    The user module is easy to use – it can be activated with just one checkbox. The router must be connected to the Internet in order to use FOTA updates. The module checks for the new cellular module firmware every 24 hours. It is also possible to check ...

    Patch for R-SeeNet – Alphanumeric SN


    Written by Petr Hanuš on Thursday 8 February 2018 in the category Default.

  • Be the first to comment
  • Since January 2018, we have been using alphanumeric form of product serial numbers. An example of such number could be:

    ACZ1100123456787

    There are some ideas hidden behind the new serial number scheme but this post is about R-SeeNet.

    For those unfamiliar with R-SeeNet, it is a legacy Router monitoring tool that is still being supported and maintained.

    If you are using this tool, you need to update it via patch linked below to get reasonable level of support for the new serial numbers. Without this patch, the new serial numbers are not being displayed ...

    Written by Petr Hanuš on Monday 29 January 2018 in the category Release with the tags , , .

  • Be the first to comment
  • As you know, Conel OS 6.1.5 was released before Christmas with a few usual exceptions (SmartFlex SR305, SmartStart SL302, SPECTRE v2). Now, this firmware is also released for SmartFlex SR305 and SmartStart SL302 routers designed for the North American market.

    Pointing out a few notable changes:

    • Fixes for multiple Wifi vulnerabilies (KRACK and other CVEs).
    • All sensitive information in the text dialogs like passwords and pre-shared keys is now not visible in the UI so nobody looking over the shoulder is able to spot passwords.
    • IPSEC fixes - improved stability plus compatibility with Checkpoint VPN ...
