# How to update my LTE450 router if I’m using the 450connect mobile network with priority plans?

> [!WARNING]
> Who is concerned?
> 
> Wenn Sie
> 
> - die 450connect-Priorisierungstarife **M2M Premium**, **M2M Business** oder **M2M Basic** nutzen **und**
> - Ihr LTE450-Router **vor dem 31.12.2026** geliefert wurde,
> 
> **müssen** Sie die Firmware des Mobilfunk-Modems aktualisieren!
> 
> Bei Verwendung der nicht priorisierten Tarife **M2M Light** sowie **Best Effort** oder anderer Tarife ist die Aktualisierung nicht zwingend notwendig, aber ebenso möglich.

Further details and background information on the need for this update can be found in our [product change notice.](https://public.centerdevice.de/578526f2-434c-4400-b426-90a5470f0c67).

> [!NOTE]
> What is the difference between the router’s firmware and the mobile modem’s firmware?
> 
> The router’s firmware is responsible for the router’s functions and user interface.
> 
> The mobile modem’s firmware only affects the cellular engine within the router. For example, it handles the connection to the mobile network and communication with the base stations.
> 
> Router and modem firmware are independent of one another. Updating the router firmware does not also update the modem firmware.

To update the modem’s firmware, your router must be running at least version 7.8 of the router firmware. If your router is running an older version of the firmware, [please update it](/kb/docs/updating-a-router-manually-en) before updating the mobile modem!

To update your router’s modem firmware, follow these steps:

1. Download the modem firmware required for your router or MRcard: ● **MRX LTE450** or **MRcard PL450**: [m3psq-ec200s-450-03-A12.tar](https://public.centerdevice.de/3939ffe7-3b7f-48db-8506-6b099a7c9730) ● **MRX LTE450D** or **MRcard PL450D**: [m3psq-eg950a-450-01-07.tar](https://public.centerdevice.de/18436e06-665d-4d4f-93e4-9b431c97b930)
2. Open the user interface of your router: https://insys.icom
3. Open the page *Administration* → *Firmware* in the menu.
4. Click in the upper right corner on and upload the firmware packet to the router.
5. Click on Submit.
6. Scroll down and click on in the row of the new firmware version and click on *Update firmware* in the upper right corner. ![](https://cdn.document360.io/c690fe99-a3eb-474c-a449-c2c75e5df119/Images/Documentation/image(764).png)
7. Click on Activate firmware.

The router updates the firmware of the cellular modem and restarts. This completes the update.
