[Solved] Intel PRO/Wireless 3945ABG - No wireless conecction

Hi, sorry for my bad english.

Since I update to kernel 2.6.33 the wireless interface doesn't work.

The output of lspci -v

        Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
        Subsystem: Hewlett-Packard Company Device 135b
        Flags: bus master, fast devsel, latency 0, IRQ 30
        Memory at f4300000 (32-bit, non-prefetchable) [size=4K]
        Capabilities: [c8] Power Management version 2
        Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+

        Kernel driver in use: iwl3945
        Kernel modules: iwl3945

I followed the instructions in the wireless wiki, the output of ifconfig -a:

          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off

when I try ifconfig wlan0 up:

ifconfig wlan0 up
SIOCSIFFLAGS: Unknown error 132

My networkmanager is Wicd and say that "No wireless connection"

I try this:

[root@myhost ~]# modprobe -r iwl3945
[root@myhost ~]# modprobe iwl3945
[root@myhost ~]# ifconfig wlan0 up
SIOCSIFFLAGS: Unknown error 132

And I have the same error.

Thanks for your help.

Does your laptop have a wifi hardware switch or a setting in the BIOS to disable wifi?

Install rfkill from [core] and run rfkill list. What was the latest kernel that worked?

Yes, my laptop have a switch, but the wi-fi works on windows.
The output of rfkill list

[sonwill@myhost ~]$ rfkill list
0: hp-wifi: Wireless LAN
        Soft blocked: yes
        Hard blocked: no
1: phy0: Wireless LAN
        Soft blocked: yes
        Hard blocked: yes

Tanks for help

Does running "rfkill unblock 0" or "rfkill unblock 1" as root make any difference?

rfkill unblock 0 and rfkill unblock 1 works perfect, now I have wireless again.

Thanks for help.

pd: whit kernel 2.6.32 the wifi worked fine, but after update to kernel 2.6.33 does not.  what is the reason for this?
