Would it be possible to have a captive portal enabled on a specific SSID (mac address limited) on which everyone can connect without having to fill in a username/password? But with a quota of 10GB/day enabled?
We would like to have a specific SSID for devices which are not capable of filling in a username/password however with a maximum daily usage.
Yes, but it requires you to host an external captive portal splash page then when hit by the device authenticates it automatically.
Here is a KB article about how captive portal auth works.
