        so even tho the chip set is for BSD it will only get wireless G speeds

          Because even though there are some drivers for 802.11N chipsets there is no kernel support for the protocols required to make use of the addtional bandwidth, as I understand it.  ;)
          802.11N support is a work in progress in FreeBSD and different chipsets will have wildly varying levels of functionality. That's if you're running the very lastest bleeding edge code. pfSense is a security platform that cannot afford to use unstable code hence it's built on tried and tested FreeBSD 8.1 (8.3 for 2.1 snapshots).

            so would this chip work ??  http://www.ebay.com/itm/JJPLUS-MR2-Atheros-AR9220-802-11N-BG-1000mW-Minipci-/110740291506?pt=DE_Computing_Notebook_Porterweiterungskarte&hash=item19c8a2bfb2

              The AR9220 which that card uses does seem to be supported by the ath(4) driver. See:
              http://www.freebsd.org/cgi/man.cgi?query=ath_hal&sektion=4&apropos=0&manpath=FreeBSD+9.1-RELEASE
              However that's from FreeBSD 9.1 and pfSense 2.1beta is built on 8.3. But I believe the driver may have been back-ported, try searching the 2.1 subforum.
              Even so you will only see 'G' speeds because not all the required components are there:
              @https://wiki.freebsd.org/WiFi80211n:

              The following 802.11n features would be nice in the short term:

              802.11n rate control/selection in net80211 - currently, the rate control modules in net80211 only know about legacy rates

              That is from Sep. 2012 so things may have advanced since then.

                I know this may not help but it does see the wifi card is there

                  Unfortunately you're right, it doesn't help.  ;)
                  The fact that is is assigned as 'none' means that no driver has attached to it.

                    The 8086 code in the chip field indicates its an Intel chip. But you were inquiring about an Atheros chip. The Linux PCI IDs file says that is a Centrino Wireless-N 2230 chip. No driver attached strongly indicates there is no supported driver for it.

                      I assumed this is the card first asked about, in the first post.

                        yes it was the first chip i talked about an i was wanting to replace it with the Atheros Chip  but i dont know about the 1,000mw

                          You are unsure if 1000mW is legal in the US?
                          You can always use a very bad antenna! The legality of the rig is the combination of the output power and the antenna gain. You can still be over the limit even with a low power card if the antenna has sufficient dB gain.
                          The driver has a setting to limit the output power anyway so you could just turn it down.
