Atheros ath0: device timeout errors

  • Hi all
    I have installed pfsense 2.2.6-RELEASE on a PC Engines APU2C4 board, with a Compex WLE200NX WiFi mini-PCIe adapter.

    The WLE200NX is detected as ath0 but the card doesn't seem to transmit any SSID I configure, and I'm getting regular 'ath0: device timeout' errors - maybe one every minute or so, but it does successfully pick up my home Wifi SSID using the pfSense UI Status/WiFi/Rescan.

    Some information that might be useful below.

    From what I've read it looks like the Atheros AR9280 chipset is supported but I don't really know where to go from here.  Any help or advice very much appreciated.


    enabling HT modes
    ath0: [HT] 1 stream STBC receive enabled
    ath0: [HT] 1 stream STBC transmit enabled
    ath0: [HT] 2 RX streams; 2 TX streams
    ath0: AR9280 mac 128.2 RF5133 phy 13.0
    ath0: 2GHz radio: 0x0000; 5GHz radio: 0x00c0
    wlan0: changing name to 'ath0_wlan0'
    ath0_wlan0: promiscuous mode enabled
    ath0: device timeout
    ath0: device timeout
    ath0: device timeout

    Also, athstats gives me this output.  Not sure if the ioctl errors at the beginning are normal or not
