    I have the same problem on a ThinkPad T41.

    Device is:
    ath_hal: 0.9.14.9 (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413)
    ath0: <Atheros 5212> mem 0xc0210000-0xc021ffff irq 11 at device 2.0 on pci2
    ath0: Ethernet address: 00:05:4e:4b:76:13
    ath0: mac 5.6 phy 4.1 5ghz radio 1.7 2ghz radio 2.3

    Sysctls:
    dev.ath.0.countrycode: 0
    dev.ath.0.regdomain: 97

    I tried setting hw.ath.countrycode to 752 (sweden) but the driver
    complained on boot that it was invalid. It was zero with the old
    kernel too.

    The card works fine in ad-hoc mode without wep, if I enable wep it breaks.
    The funny thing is that on the other end I can see ARP requests but no
    replies are sent when wep is on (other end is a ~3 weeks old current with
    a cisco aironet 350 card). "status" claims "associated", everything looks
    the way it should be.

    I also get a couple of these from time to time, could be related to
    reconfiguration.
    ath0: device timeout
    ath0: device timeout
    ath0: device timeout

    Another minor thing I noted, when you play around with 'ifconfig ath0 wepmode'
    it looks like the wepkeys are displayed sometimes and sometimes not afterwards,
    it seems very random. It it required to set wepkey and wepmode in the same
    command?
