      Hmm, I've not tried those two pieces of hardware (yet!) but I have one running great in the APU.
      Some things I found were:
      To run any sort of 'N' mode you must have WME enabled, be using WPA and select a valid region. You look to have done that.
      If you select a channel that isn't valid in your selected region you will get nothing, like you're seeing.
      I never got NA mode to work but I don't have any 'A' devices to test with.
      Do you have any crash reports?

        I've sent several in via the gui (and then deleted them).

        My last crash was caused by simply changing the WPA PSK. :)

        I saved the entire dump if you would care to have a look, but the most pertinent sections are:

          Hmm, interesting. Certainly looks at first glance to be some driver issue though it works flawlessly in the APU.
          Are you able to try both miniPCIe slots?

            I'm a bit reluctant to open it up until I talk with the pfSense store folk.

            I just had to do the install on Easter weekend… :)

              Ah, OK it came with the card installed already?

              These things are so new you guys have them before we do.  ;)

                  Okay, after a few dozen more tests…

                  I've learned that to get consistent results, I need to make the changes in the interface, halt the system, and remove the power cord for a few seconds.

                  Here is where I am at as a baseline:

                  Persist common settings off
                  Standard 802.11ng
                  Protection mode off
                  Channel 11b/g/n
                  Transmit antennas auto and auto
                  Regulatory domain FCC
                  Country United States (US, FCC)
                  Location indoor
                  Mode Access Point
                  SSID Test
                  Minimum wireless standard Any
                  Enable WME on
                  Enable WEP off
                  Enable WPA off

                  With this configuration, the system will boot. The Status->Wireless page will show several other APs within reach. Based on this, I assume that the PCIe connection is functional.

                  The AP Test does not show up as advertised on the wifi scanner. Nor can it be joined.

                  If I change the mode to Ad-hoc without removing the SSID, the system will crash on boot.
                  If I change the mode to Ad-hoc but change the SSID to blank, the system will boot.

                    Did you try to run some Linux on it to check whether the wifi works at all?

                      I'm not sure I understand the question.

                      Are you asking if I've installed Linux on the pfSense hardware as a test? If so, then no I haven't.

                        Yeah… that's exactly what I'm asking.

                          Just for testing have you tried creating an Access Point without WPA or WPA2, just to eliminate WPA supplicant as a culprit?

                          Also under System Logs>>Wireless what does it show??

                            You will need to have WPA enabled to create an AP with 'ng' mode selected as I understand it.

                              Yes, in G mode.

                                  Nope, just rekey messages.

                                    Just for the record, WPA/2 is not required for AP mode, in G or NG/NA mode. I just tested to ensure nothing changed. I know some field verification was added for ease of setup in wireless.
                                    In fact WAP is not checked by default.

                                      For N, you need either WPA2 or no authentication whatsoever. WEP/WPA not supported.

                                        Well I may not have been much help but i had to ask some of those basic questions..
                                        Good luck, i am sure the support crew will get you going in no time.

                                          Yeah, even if you choose wpa or both if you check the encryption used it's wpa2.

                                            At a minimum, it would appear that pfSense isn't invoking ifconfig correctly:

                                            Even with a standard of 11na and channel 36 specified in the config, ifconfig ath0_wlan0 reports
