Updated to iwlwifi-firmware 0.13.

stefano@geppetto ~> uname -a
Linux geppetto 2.6.26-1-686 #1 SMP Thu Oct 9 15:18:09 UTC 2008 i686 GNU/Linux


stefano@geppetto ~> sudo modprobe -r iwl3945
stefano@geppetto ~> sudo modprobe iwl3945

with dmesg I get:
[  332.178973] iwl3945: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, 1.2.26ks
[  332.178973] iwl3945: Copyright(c) 2003-2008 Intel Corporation
[  332.178973] ACPI: PCI Interrupt 0000:10:00.0[A] -> GSI 17 (level, low) -> IRQ 17
[  332.178973] PCI: Setting latency timer of device 0000:10:00.0 to 64
[  332.178973] iwl3945: Detected Intel Wireless WiFi Link 3945ABG

[  332.218972] phy0: Selected rate control algorithm 'iwl-3945-rs'

stefano@geppetto ~> sudo iwconfig
lo        no wireless extensions.

eth1      no wireless extensions.

wmaster0  no wireless extensions.

wlan0     IEEE 802.11  ESSID:""  
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated   
          Tx-Power=0 dBm   
          Retry min limit:7   RTS thr:off   Fragment thr=2352 B   
          Encryption key:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

So the module looks correctly loaded.

stefano@geppetto ~> sudo iwlist wlan0 scanning

Here it hangs for 30 seconds more or less, then I get this:

wlan0     Interface doesn't support scanning : Network is down

From dmesg:
[  372.025418] firmware: requesting iwlwifi-3945-1.ucode
[  432.097666] iwl3945: iwlwifi-3945-1.ucode firmware file req failed: Reason -2
[  432.097676] iwl3945: Could not read microcode: -2

stefano@geppetto ~> locate  iwlwifi-3945-1.ucode
/lib/firmware/iwlwifi-3945-1.ucode

Hints will be highly appreciated.

Regards.
