I have no problem at startup connecting to a linksys wrv200 using wpa-psk using wpa_supplicant, but I get the seemingly random disconnects. When I get the disconnect, ifconfig looks good except that the status shows not associated. Executing /etc/rc.d/netif restart will usually get a reconnect on the first try. It seems to be a wpa issue as using WEP on the same hardware results in a stable connection. On another note, can you get your notebook to suspend (S3)?
