with wpa_supplicant, only broadcast/multicast packets received, none transmitted

I have a Fedora Core 2 system (laptop) with hostap-driver-0.2.2 and
wpa_supplicant-0.2.2 installed.  I am simply trying to set up a wpa
protected connection from this laptop to an SMC 7004VWBR AP.

The access point and it's WPA configuration seem to be good as this all
works with the laptop and winxp.

As far as the wpa_supplicant configuration goes, it seems to be good as
this log shows success (doesn't it?):

The problem is that despite this, the only traffic that seems to go
between the laptop and the LAN the AP is on is broadcast and multicast
traffic from other hosts on the LAN.  I have determined this by running
tcpdump on the laptop on the wlan0 interface.

Here is the iwconfig wlan0 output:

wlan0     IEEE 802.11b  ESSID:"ilinx"
          Mode:Managed  Frequency:2.437GHz  Access Point: 00:04:E2:B2:C9:52
          Bit Rate:11Mb/s   Sensitivity=1/3
          Retry min limit:8   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality:54/70  Signal level:-37 dBm  Noise level:-91 dBm
          Rx invalid nwid:0  Rx invalid crypt:77  Rx invalid frag:0
          Tx excessive retries:11  Invalid misc:15   Missed beacon:0

and the wpa_supplicant.conf:

ctrl_interface=/var/run/wpa_supplicant
eapol_version=1
network={
        ssid="ilinx"
        psk=abcdef...123456
}

Ideas?  Any further information needed?

Thanx,
b.
