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? Erik Winge
