This Article Applies to:

All Omada routers.

Issue Description/Phenomenon:

A very few users, when you upgrade to the latest firmware(or any firmware released after Dec 2023) from the current firmware(non-factory default), there is a chance that you failed to upgrade auto/manually and you might see the error "upgrade failed: The upgrade file is invalid. Please select a correct file."

Available Workarounds/Solutions:

If you are using the software Omada Controller, please make sure your installed Java on this system is 64-bit.

• Run "java -version" in Command Prompt and you should see your version. Even if it shows as 64-bit, we still recommend you do a clean reinstall.
• Perform a clean uninstall on your computer to remove any Java environment. Download the 64-bit and install it again.

This will fix your problem when seeing that specific error.

Thank you for your attention!
