Change Login and Hotspot Pages
You probably want to change the login or other hotspot pages, such as adding your company name or welcome message, or even plopping in logos and images. Some HTML knowledge or understanding helps.
To download and upload the HTML files from RouterOS, you can use a FTP client, such as FileZilla, and connect to the RouterOS IP with your administration account credentials.
If you prefer that users are redirected to a specify site or page after logging on, edit the login.html file to replace $(link-orig) with the full URL. This is the default value for the dst (destination) hidden attribute within the Form tags.
If you link to locations on the Internet, including images, you must add their domain to the Walled Garden list in order for users to access them before logging on. This is available on a tab of the Hotspot window in WinBox.
