No udev support for iwl3945?

I am getting stuck trying to determine how to get my wireless card on my dell latitude D630 to be brought up when I enable the radio that controls the card and the bluetooth support.

I have tried "udevadm monitor --environment --kernel --udev" and I only see USB-bluetooth related events (though it is possible I missed something).

The lspci data on the card is:

Code:

0c:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)

        Subsystem: Intel Corporation Unknown device 1020

        Flags: bus master, fast devsel, latency 0, IRQ 220

        Memory at fe8ff000 (32-bit, non-prefetchable) [size=4K]

        Capabilities: [c8] Power Management version 2

        Capabilities: [d0] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable+

        Capabilities: [e0] Express Legacy Endpoint IRQ 0

I am using the iwl3945 driver.

Here are some problems I am having:

Enabling the radio does not bring the interface up
Sometimes the link strength is 0
When the link strength is 0, "modprobe -r iwl3945" will peg the CPU and the kernel appears to panic on reboot
Ifplugd cannot bring the device up (udev related?)
My wireless LED never works despite iwl3945 advertising it should

I have tried "auto wlan0" in the /etc/network/interfaces, but this seems to make it more unreliable. I have also tried hot plug settings and also using similar settings with ifplugd with no effect.

I am running Xubuntu Hardy. Kernel:
2.6.24-19-generic #1 SMP

I am running out of ways to diagnose this. Perhaps it is a problem in the iwl3945 driver in the provided ubuntu kernel?

Thanks for any help.

try other drivers?
I know theres: iwl3945, ipw3945, intelwifi or something like that, etc

I KNOW it's on sourceforge somewhere.... intel3945.sourceforge.com or something.

when I was on backtrack2 as my distro, the LEDs never came on until I used the wlanassistant, then they turned on..

sorry,it's still very early here, I'm not completely "there" but as soon as I get into the office I'll post all the correct links, as I had to patch that damn wifi chipset yesterday and kept all the links..

iw3945 is deprecated and I have had issues with it to in the past (stops working after a period of time). iwl3945 is part of iwlwifi, which is the official, but seemingly no better, set of drivers.

By the way I solved this by writing a udev script against bluetooth events. The radio switch governs bluetooth too, so it is a hack but it works.
