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:
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.
