How to implement portal authentication for dumb terminals such as printers in a wireless environment?

 These terminals often do not have the ability to interact with the portal.

Solution1: Enable MAC-triggered+portal-based MAC unaware fast portal authentication. After the terminal is connected to the network and obtains an IP address, it will first undergo a legality check for the MAC address. The authorization server, such as IMC, adds the MAC address of printers and other devices as a permanent and unaware table item, enabling normal internet access.

Solution2: Enable MAC or portal authentication (often chosen when the server does not support MAC-triggered). Pre-write the MAC address of dumb terminals on the RADIUS server. When the wireless device is associated with the WiFi, MAC authentication verification will be performed. Since the MAC address of a dumb terminal has already existed on the server, internet access can be completed.

Solution3: Open another SSID with an unencrypted and unauthenticated open mode, often set as a hidden SSID for better effect. The network manager only needs to associate the dumb terminal operation with the specified SSID name to achieve internet access, and the other ordinary users cannot see this SSID, thus not causing any management or usage confusion.
