I'm not sure if that is correct, as I am not 100% familiar with the terms.
Yes I have combined network set, however the wireless SSID access (under the wireless main heading Wireless not Security and SD-WAN-> Wireless) is set for WPA2 PSK and is configured for a Splash page with sign-on for Meraki Cloud Authentitcation.
However as there is also a requirement for wired connections for customers to plug in a device, I want to be able to configure a sign-on page to use the same authentication option. I don't understand why I can't have a wired link point back to the same user database as the Wireless SSIDs are already using. I can only assume this is a software limitation that has not been written. I can configure a click through splash page that is identical to the Wireless one, however I cannot configure it to authenticate the same way.
I have also raised this through the make a wish button, however at this stage my only option is to allow wired connections to have unfettered access without signing in, as we do not have any infrastructure to use a radius server on this system.
