Ok, let me describe what happens on my machine. When I load the module 
with 'modprobe ipw3945', the daemon is started automatically, and I 
get something like this in dmesg output

ipw3945: Intel(R) PRO/Wireless 3945 Network Connection driver for Linux, 1.1.3dmpr
ipw3945: Copyright(c) 2003-2006 Intel Corporation
PCI: Enabling device 0000:0c:00.0 (0100 -> 0102)
ACPI: PCI Interrupt 0000:0c:00.0[A] -> GSI 17 (level, low) -> IRQ 177
PCI: Setting latency timer of device 0000:0c:00.0 to 64
ipw3945: Detected Intel PRO/Wireless 3945ABG Network Connection
ipw3945: Detected geography ABG (11 802.11bg channels, 13 802.11a channels)

At this point interface is not up yet, so I get the 'iwconfig' output 
(wifi interface is eth2):

[...]
eth2      unassociated  ESSID:off/any  
          Mode:Managed  Frequency=nan kHz  Access Point: Not-Associated   
          Bit Rate:0 kb/s   Tx-Power:16 dBm   
          Retry limit:15   RTS thr:off   Fragment thr:off
          Encryption key:off

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:15   Missed beacon:0

Then I run 'ifup eth2', machine gets an IP address from access point 
from DHCP:

sudo ifup eth2

After that iwconfig displays the parameters of the connection and 
of the access point. 

Can you please go through the same steps, running the same commands 
and letting me know where you are getting something different?

Thanks,
