Can't connect to wireless network

[Code Epicure <ce CodeEpicure com>]

Finally, after help from many people on the web, I have gotten ndiswrapper loaded correctly for the BCM4318-based wireless card on my Acer 5000 (Turion 64) laptop running FC5.  Since I did it wrong so many times it feels really nice to have it working.  There is only one problem - it won't connect to my wireless router.  NetworkManager (0.6.0, I think) shows my wireless network, plus a few belonging to neighbors, but when I click on my network it says 'Attempting to join the wireless network "Reading"...' and then eventually fails.  What am I doing wrong?  I can offer the following output from iwconfig:

wlan0     IEEE 802.11g  ESSID:"CodeEpicure"  
          Mode:Managed  Frequency:2.412 GHz  Access Point: 00:20:E0:3F:CE:35   
          Bit Rate=54 Mb/s   Tx-Power:25 dBm   
          RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality:100/100  Signal level:-44 dBm  Noise level:-256 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:115  Invalid misc:49690   Missed beacon:0

What little I know about my network looks correct on there.  When I had NM and ndiswrapper working under FC4 it just worked.  Maybe I was lucky.  Thanks for any and all help.
