A couple of suggestions:
1) I had very similar problems with some of the Broadcom drivers for my
laptop ("transaction took too long"). An easy test is to *BRIEFLY* disable
security on the AP and see if your system connects. If the two systems
connect then there is a problem syncing with WPA security. A possible
alternative is to use ndiswrapper and the Windows driver instead of the
native Linux driver. I've been really happy with ndiswrapper even if it
means I'm "impure" for using a Windows driver.
2) The actual key exchange is handled by a daemon called wpa_supplicant.
It can be finicky. The config files are /etc/sysconfig/wpa_supplicant
and /etc/wpa_supplicant/wpa_supplicant.cnf You may have better luck
fiddling with some of the settings in the configuration files. As an
example, ndiswrapper works better for me with -D wext instead of -D
ndiswrapper.
I've also seen restating wpa_supplicant (as root, "service wpa_supplicant
restart) fix things. Also, I've had better luck just getting the
wpa_supplicant configuration right and not using NetworkManager (service
NetworkManager stop). I just do a "ifup wlan0" from the command line.
Cheers,
Dave
