I have the same hardware you do (inspiron 9400, intel 3945) running
7-stable (really 7.1 pre-release at this point) . 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)?
