    While searching for a solution to blocked wifi on a netbook where rfkill did not work I came across some information
    from archwiki. Many thanks to the Archers who with so much in depth knowledge have helped me in many situations.
    URL to the full article is at end of post !.
    Hopefully this will be of help to other antiX users with wifi problems.

    $ connmanctl enable wifi was in my case the key to unblocking.

    # Warning: connman grabs rfkill events. It is most likely impossible to use rfkill or bluetoothctl to (un)block devices,
    yet hardware keys may still work.[1] Always use connmanctl enable|disable

    Hardware interfaces are referred to as Technologies by ConnMan.

    To list available technologies run:

    $ connmanctl technologies

    To get just the types by their name one can use this one liner:

    $ connmanctl technologies | awk ‘/Type/ { print $NF }’

    Note: The field Type = tech_name provides the technology type used with connmanctl commands

    To interact with them one must refer to the technology by type. Technologies can be toggled on/off with:

    $ connmanctl enable technology_type

    To toggle on wifi:

    $ connmanctl enable wifi


    $ connmanctl disable technology_type

    To toggle off wifi:

    $ connmanctl disable wifi

    Using connmann interface for diagnostic or connection:

    $ connmanctl scan wifi

    To list the available networks found after a scan run :

    $ connmanctl services

    (example outputbelow)
    *AO MyNetwork wifi_dc85de828967_68756773616d_managed_psk
    OtherNET wifi_dc85de828967_38303944616e69656c73_managed_psk
    AnotherOne wifi_dc85de828967_3257495245363836_managed_wep
    FourthNetwork wifi_dc85de828967_4d7572706879_managed_wep
    AnOpenNetwork wifi_dc85de828967_4d6568657272696e_managed_none

    To connect to an open network, use the second field beginning with wifi_:
    $ connmanctl connect wifi_dc85de828967_4d6568657272696e_managed_none

    For password protected wifi:

    For protected access points you will need to provide some information to the ConnMan daemon, at the very least a password or a passphrase.

    The commands in this section show how to run connmanctl in interactive mode, it is required for running the agent command. To start interactive mode simply type:

    $ connmanctl

    You then proceed almost as above, first scan for any Wi-Fi technologies:

    connmanctl> scan wifi

    To list services:

    connmanctl> services

    Now you need to register the agent to handle user requests. The command is:

    connmanctl> agent on

    You now need to connect to one of the protected services. To do this easily, just use tab completion for the wifi_ service. If you were connecting to OtherNET in the example above you would type:

    connmanctl> connect wifi_dc85de828967_38303944616e69656c73_managed_psk

    The agent will then ask you to provide any information the daemon needs to complete the connection. The information requested will vary depending on the type of network you are connecting to. The agent will also print additional data about the information it needs as shown in the example below.

    Agent RequestInput wifi_dc85de828967_38303944616e69656c73_managed_psk
    Passphrase = [ Type=psk, Requirement=mandatory ]

    Provide the information requested, in this example the passphrase, and then type:

    connmanctl> quit

    If the information you provided is correct you should now be connected to the protected access point.
    Settings. Warning here, some special characters are not always accepted in passwords.

    On old hardware:
    For a 40 bit WEP network the password is 5-characters.
    For a 128 bit WEP network the password is 13-characters.
    The now usual WPA uses either a passphrase (a shared secret) that is comprised of 8 to 63 characters or a fixed-length of 64 HEX characters.

    For networks the user connects to often Settings and profiles are automatically created . They contain fields for the passphrase, essid and other
    information. Profile settings are stored in directories under /var/lib/connman/ by their service name.

    To view all network profiles run this command from root shell:

    # cat /var/lib/connman/*/settings

    VPN settings: # cat /var/lib/connman-vpn/.

    All interfaces of connman (in antiX full cmst, in antiX base, connman-ui) are comunicating with the real connman service conmanctl

    If you launch in terminal
    You will see that the terminal input has changed. Inside that change, see what
    outputs. It should tell you all detected interfaces and if they are on/off.
    For wlanX interfaces, it usually identifies them as “wifi”. We need to know how it identifies your eth1 interface.

    Let us imagine that it identifies it as “wifi”

      Name = Wifi
      Type = wifi
      Powered = False

    We need to enable it
    enable wifi
    and check technologies again

      Name = Wifi
      Type = wifi
      Powered = True
      Connected = False

    To make sure it can scan, you run
    scan wifi
    If it spits out an error, lets try restarting connman. Exit connmanctl with
    and restart connman service
    sudo service restart connman

    Then again enter connmanctl and scan again

    > scan wifi

    If everything goes well, you will see that scan was a success, and see your wireless connections with

    If it is there, exit connmanctl with quit and try to use the connman gui to connect to your wireless AP.

    If there is no wifi option, paste the connmanctl technologies output so we may see.
