captive_portal.json file

• Edit the file /etc/MESHdesk/configs/captive_config.json.
• This file is a JSON structure that the device uses as a reference to configure itself with a special captive portal when it is not yet managed by the controller.
• There are only two items that might need to be tweaked
  • The radio number for the 2.4G band.
  • The ports for the br-lan device (We use the WAN port in out implementation)
• With the Xiaomi 4A 100M Edition radio0 is the 2.4G radio so no need to tweak that item. (If the hardware has radio1 as the 2.4G band simply look for all the references to radio0 and make them radio1)
• See this snippet of a device which has radio1 using the 2.4G band

• With the Xiaomi 4A 100M Edition the port we use is eth0.1 for the br-lan device definition.

{
    "device": "br-lan",
    "options": {
        "name": "br-lan",
        "type": "bridge"
    },
    "lists": {
        "ports": [
            "eth0.1"
        ]
    }
},  

• With the Xiaomi 4A Gigabit Edition it will look like this

{
    "device": "br-lan",
    "options": {
        "name": "br-lan",
        "type": "bridge"
    },
    "lists": {
        "ports": [
            "wan"
        ]
    }
},  

• Once the tweaks are completed we can test everything out.
