    Hi Ferri

     

    It appears that you have the latest firmware v20.06.09.00 installed. 

     

    Kindly access LM1200 settings page, go to Settings > General > Software and Reset > click the Check for update button. This will allow the modem to check for new firmware. 

     

    And for the manual update, did you load the SPK file and not the ZIP file?

    Please collect a model.json file and send back to me via private message. 

    - Logon to the webui (http://192.168.1.1 ) as an administrator
    - Navigate to URL http://192.168.1.1/model.json via the same browser window
    - Capture the results (by selecting all + copy) and send it back
