Archer C9 with pfSense / Archer T9E Compatability

[wtavares]

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.
