Hi, you need to disable the switch inside your kernel,recompile your kernel, copy it inside /boot, and reboot.

It's done. My kernel is configured as you told me before:

Code:

-*- Networking support --->
<M> RF switch subsystem support --->
--- RF switch subsystem support
<M> Input layer to RF switch connector
Device Drivers --->
[*] Network device support --->
Wireless LAN --->
[*] Wireless LAN (IEEE 802.11)
{M} Intel Wireless Wifi Core
[ ] Iwlwifi RF kill support
[ ] Enable full debugging output in iwlagn driver
<M> Intel Wireless WiFi Next Gen AGN
[*] Enable Spectrum Measurement in iwlagn driver
[*] Enable LEDS features in iwlagn driver
[ ] Intel Wireless WiFi 4965AGN
[*] Intel Wireless WiFi 5000AGN

You need to remove this :

Code:

*- Networking support --->
<M> RF switch subsystem support --->
--- RF switch subsystem support
<M> Input layer to RF switch connector

You don't need that at all.

Hi, for your switch problem, make sure that you have disable this section :

Code:

(M) RF switch subsystem support
(M) Input layer to RF switch connector

You don't need this since your hardware swtich doesn't work on Linux.

And rfkill module isn't loaded:

Code:

Ok since, now reboot and run this :

Code:

# modprobe iwlagn
# /etc/init.d/net.wlan0 restart
# ifconfig -a

just a thought (I have iwl5100 on my x64 setup and it works)

Code:

cat /sys/module/rfkill/parameters/default_state

PS; old miniPCIs had a pin (number 6 I guess) that controlled rfkill, and if you blinded it than the card would work all the time, maybe miniPCIe has something similar :-)

While rfkill module is loaded i can see:

Code:

dv5 define # cat /sys/module/rfkill/parameters/default_state
1

To blind it physically?

In fact,

Code:

iwlagn: Radio disabled by HW RF Kill switch

it's not good at all.

So we really need to figure this out for your hardware switch and after that it will be a walk in a park.

I'm sure a proper patch would be better than modifying by hand, but this is how I got mine up and running quickly. I'm using linux-2.6.27-gentoo-r4 kernel. You can use "locate iwl-agn.c" to find the file location.

Hi, here what you need to do :

Remove this line :

Code:

if (!hw_rf_kill && !test_bit(STATUS_ALIVE, &priv->status))

And replace it by this code :

Code:

if (!hw_rf_kill && !test_bit(STATUS_ALIVE, &priv->status)) {
clear_bit(STATUS_RF_KILL_HW, &priv->status);
if (priv->is_open && !iwl_is_rfkill(priv))
queue_work(priv->workqueue, &priv->up);
}

And you need to add theses lines :

Code:

/* when driver is up while rfkill is on, it wont receive
* any CARD_STATE_NOTIFICATION notifications so we have to
* restart it in here
*/
if (priv->is_open && !test_bit(STATUS_ALIVE, &priv->status)) {
clear_bit(STATUS_RF_KILL_SW, &priv->status);
if (!iwl_is_rfkill(priv))
queue_work(priv->workqueue, &priv->up);
}

/* If the driver is already loaded, it will receive
* CARD_STATE_NOTIFICATION notifications and the handler will
* call restart to reload the driver.

I see it, but what exact place in this file?

Just in the end after the following?

Code:

{
pci_unregister_driver(&iwl_driver);
iwlagn_rate_control_unregister();
}

module_exit(iwl4965_exit);
module_init(iwl4965_init);

I see in diff output line number 1656, but I've got some other lines there, which don't seem to be

Code:

return 0;
}

So i can't understand where should be that lines add.
