Looks like a rfkill related problem. Can you please try this patch?

Your radio is disabled by the software rf_kill switch. Please do a
$ echo 0 > /sys/bus/pci/drivers/iwl4965/<dev id>/rfkill\:rfkill0/state
I wonder if you (or some application) did something like a `iwconfig

wlan0 txpower off` so that the radio is disabled. Maybe you can try

`iwconfig wlan0 txpower on`?
Thanks,

mac80211 in those (old) kernels doesn't indicate to switch the SW

rf_kill on with user sets txpower off.
Thanks,

Oops, you should echo 1 instead.

Hi,

With "0" and "1" result the same - failed.

Hi,

If I reload kernel module, I get rfkill[n] with new [n].

rfkill0

rfkill1

rfkill2

After reloading I always get 0 int state

/sys/bus/pci/drivers/iwl4965/0000\:04\:00.0/rfkill\:rfkill2/state

0
I attached files form console log and dmesg

console-rfkill-0.txt

Hi,

ok, i pached.

Results (failed) in attached files:

console-rfkill-1.patch.txt

dmesg-2.6.26-rc7_2008-06-24-rfkill-1.patch.txt

Looks like the wireless config scripts in your distro did something

(probably txpower off) to disable the SW radio. Can you try the

following commands after wlan0 restart?
$ cat /sys/bus/pci/drivers/iwl4965/0000\:04\:00.0/rfkill\:rfkill1/state

$ echo 1 > /sys/bus/pci/drivers/iwl4965/0000\:04\:00.0/rfkill

\:rfkill1/state

$ ifconfig wlan0 up
Thanks,

Hi,

with new build -rc9 iwl4965 still don't work.

I don't know, witch distro I should use to check, that current kernel and my

WiFi is OK.
I returned to good 2.6.24-gentoo-r8
--

don't see any other report on this. Could you please file a bug on

bughost.org so we can track it there?
Thanks,

-yi
--

Hi,

my WiFi still don't wokrk

Now, I have new kernel 2.6.26-rc8.
Should I patch again this kernel?

Is good patch for rc7 for rc8?
--

Hi,

I do

 ifconfig wlan0 up
results in files:

console-frkill-1-iwconfig.txt

dmesg-2.6.26-rc7_2008-06-24-rfkill-1-ifconfig.txt

net - script config

net.lo - run script
How to run my wifi?

Hi,

Still don't work.

I have tested this patch with and without RFKILL kernel settings

Can you please load the module with "debug=0x20002" and attached the

dmesg?
Thanks,

I checked:

- vanilla-sources-2.6.24.7 (works),

- gentoo-sources-2.6.25-r4 (don't work)
I uploaded files:
