    I experience more weirdness. It seems the card will disassociate from
    the ap if there is no network activity for some time.

    If I use the network, for instance streaming audio or having a
    mailprogram check mail regularly, everything works fine. However if I
    close all programs, and leave the computer alone for some minutes, it
    will lose the network connection. ifconfig then reports status:no
    carrier

    I have tried running "wpa_cli reassociate", but it doesn't find my ap,
    and I have to kill wpa_supplicant and restart it to reconnect. Is
    this a driver problem, or could it possibly be wpa_supplicant?
