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?
