Archer C9 with pfSense / Archer T9E Compatability



  • This is my current setup.

    Surfboard Modem -> pfSense Box (192.168.0.1 || 255.255.255.0/24) -> Archer C9 Router (AP Mode) (192.168.1.1 || 255.255.255.0)

    The router is dual band, but only the 5 GHz band works. The 2.4GHz band won't connect to the pfSense box. Did I do something wrong when I set it up?

    As an aside, is an Archer T9E compatible with pfSense?

    Sorry if i left out any pertinent information, just getting into home networking.

    Create two SSIDs and then please put each in a own VLAN in pfSense and create a own DHCP for each network
    with his own IP range such like this;

    • 2,4GHz - SSID - private24 - 192.168.1.0/24
    • 5,0GHz - SSID - private50 - 192.168.2.0/24
    • 2,4GHz - SSID - guest24 - 192.168.3.0/24
    • 5,0GHz - SSID - guest50 - 192.168.4.0/24

    Activate client isolation and set them up as running in AP mode in pfSense.
