      thanks. I plugged a laptop straight into OPT1 - laptop is not getting IP.
      in firewall rules, for WLAN I have  have an ALLOW all from WLAN net to *
      DHCP is enabled on OPT1

      I've now seen you mention igb3, OPT1 and WLAN. I'm assuming they are all referring to the same interface, but are they really?

      If yes, please stick with calling it only a single name.

      Remember that what is obvious to you isn't to us as we don't see the screens you're looking at.

        Yes, you are correct and right..  OPT1=WLAN=igb3

                Post screenshots of your DHCP configuration and firewall rules for the WLAN interface in pfSense.

                  FYI - DHCP on LAN works OK:

                    There's no need for the DHCP rule you put there in the first place. Also, there's DHCP log and there's firewall log. Look there.

                      I decided to REBOOT pfSense and ALL fixed.
                      also removed the 0.0.0.0 FW rule and still works.
                      So.. sometimes its a simple Reboot.
                      thanks to everyone who helped.

                          I'm using 3 Linksys routers (as dumb AP devices) loaded with DD-WRT for the last …. many years !
                          Version : Firmware: DD-WRT v24-sp2 (10/10/09) std

                          My wifi network is hooked up to pfSense, OPT2, using 192.168.2.1/24.

                          AP1 has IP 1912.168.2.2
                          AP2 has IP 1912.168.2.3
                          AP3 has IP 1912.168.2.4

                          For all AP's :
                          Subnet Mask : 255.255.255.0
                          Gateway : 192.168.2.1
                          Local DNS : 192.168.2.1

                          Local DHCP server : disabled.

                          WAN Connection Type : disabled.

                          All my AP's are hooked up to pfSense using a central switch, but daisy chaining from OPT1 to AP1 to AP2 etc is also possible (I never use the WAN port, even when it is declared as another LAN port).

                          No "help me" PM's please. Use the forum, the community will thank you.
                          Edit : and where are the logs ??
