To modify the IAG captive portal custom webpage and remove WeChat and other unnecessary authentication items, you can follow these guidelines:

For IAG versions 12.0.47, 13.X, and later, go to [Access Management] - [Authentication] - [Web Authentication] - [Custom Webpage]. Here you can edit the displayed text, page background, logo, and other content directly on the interface. You can also download the default captive portal template, modify it as needed, and then manually upload it again.

When manually uploading the modified page, ensure that the compressed file directory structure is correct. A common cause of the “404” error after modification is that the compressed file has an extra directory level. You need to recompress the files properly without extra directory layers before uploading.

The uploaded custom page can be selected in the authentication policy for use. However, the uploaded page cannot override the default captive portal.

If you want to remove WeChat authentication and keep only account and self-registration methods, you should edit the template accordingly by removing the WeChat-related elements from the HTML and associated resources.

Unfortunately, a ready-made template without WeChat authentication is not provided here, but you can start from the default captive portal template downloaded from the device, remove the WeChat authentication parts, and ensure the file structure and paths (such as CSS and images) are correct before uploading.

After modifying and uploading the custom captive portal, if the authentication policy references this page, the authentication page shown to users will be updated accordingly.

Please pay special attention to the file compression and directory structure to avoid the 404 error when changing image paths or other resources
