CAX30 unable to Backup Settings

CAX30 - FW 1.4.11.2 

 

Cable Modem / Gateway is working correctly, but I'm unable to use WEB UP to "Back Up" my current settings.

"Back Up" button look like it's being selected (color changes) when I select it and click... but no file is generated back to my browser. Didn't have this problem back in Nov 2022, that the last backup I have of my settings.

 

I've tried it in:

   Windows 10 - Chrome, Firefox, Edge;

   Linux - Chrome, Firefox;

   MacOS - Safari, Chrome. Firefox

 

Any ideas what's going on or any backdoors to copy the current config that can be "Restored" via the Web UI?

    Has all browser caches been cleared out before going into the modems web page?

    Any browser security add-ons are disabled as well?

    I had the same problem, so I looked through the webpage source. I entered the URL for the Backup page directly in the browser bar -- https://192.168.1.1/BackupSettings.php -- and when I clicked the Backup button, I immediately got a Windows Save As dialog. However, Firefox then blocked downloading the file, because the file is sent over http, while the webpage itself is https, but I clicked the warning and then clicked Allow Download, and it came through.

    I suspect the hangup is a browser security feature blocking Javascript from accessing the file chooser within a frame and/or a mix of http and https on the same page.

     

    Unfortunately, the backup data is binary, and there is no way to convert it to plain text.

      Have you tried MS Edge or Opera to see if same thing happens? 

       

      What FW version are you using on your CAX30?
