      Sometimes it's caused by the "Senao" wireless card and driver combo that you are using.  I usually use a separate wireless simultaneous dual-band router as it costs about the same as buying a wireless mini-pci card and I get much better performance and pfsense stability.

      From my understanding the wireless card's firmware should "hide" the errors normally associated with wireless communications.  Might be driver compatibility issues.  FreeBSD is a bit behind when it comes to wireless AP drivers compared to Linux.

        What kind of hardware are you using with pfsense?
        I have a similar situation made worse by continiued stuck beacon messages and haven't been able to eliminate the problem completely.
        I made things better by tweaking some settings and replacing a microdrive with an industrial cf card but the problem still is there albeit on a smaller scale.

        Current network "hardware" :
        Running 2.2RC in Virtualbox 4.2.16.

        Retired:
        ALIX2C2 , 4 gigabyte disk cf card running 2.0 (official release).

          Search around in the wireless forum. From what I can determine high amounts of in errors on the interface don't necessarily mean there is a problem. A stuck beacon or the like is different, but if there doesn't seem to be a problem I wouldn't worry. I have several Alix boxes with ath cards that are running just fine- they all have huge amounts of in errors. It may well be that the ath driver does not mask 'normal' errors under some circumstances.
