Description of problem: Wireless fails to initialise on boot. From the dmesg output, it appears the RF kill switch is being activated immediately: $ dmesg | grep iwl3945 iwl3945: Detected Intel Wireless WiFi Link 3945ABG iwl3945: Tunable channels: 13 802.11bg, 23 802.11a channels iwl3945 0000:03:00.0: PCI INT A disabled iwl3945 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 iwl3945 0000:03:00.0: restoring config space at offset 0x1 (was 0x100102, writing 0x100106) iwl3945: Radio disabled by HW RF Kill switch iwl3945 0000:03:00.0: PCI INT A disabled iwl3945 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 iwl3945 0000:03:00.0: restoring config space at offset 0x1 (was 0x100102, writing 0x100106) iwl3945: Radio disabled by HW RF Kill switch iwl3945 0000:03:00.0: PCI INT A disabled iwl3945 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 iwl3945 0000:03:00.0: restoring config space at offset 0x1 (was 0x100102, writing 0x100106) iwl3945: Radio disabled by HW RF Kill switch iwl3945 0000:03:00.0: PCI INT A disabled iwl3945 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 iwl3945 0000:03:00.0: restoring config space at offset 0x1 (was 0x100102, writing 0x100106) iwl3945: Radio disabled by HW RF Kill switch iwl3945 0000:03:00.0: PCI INT A disabled This is on a Lenovo X61 laptop provided by Red Hat. Attempts to initiaise wireless by Fn+F5 appear to do nothing (though I assume they are responsible for the repeated messages above). The wireless has been working and NetworkManager was prompting to connect to WLANs it found earlier during the F10 lifecycle. This has only occurred after post-F10 updates. Version-Release number of selected component (if applicable): 2.6.27.12-170.2.5.fc10.x86_64 How reproducible: Boot the machine. NetworkManager claims wireless is enabled, but the light on the laptop is unlit. Steps to Reproduce: 1. 2. 3. Actual results: No wireless :( Expected results: Wireless :) Additional info:
I have also after update no wireless, have worked perfectly before. This must have very high priority!! Wireless is broken on all my Fedora 10 systems now.

What kernel version worked? What was the first version to fail? Are you absolutely sure that the RF kill switch is disabled (i.e. set to enable the radio)? Note, I'm not talking about Fn-F5 -- on my t61 and this t400 there are mechanical slide switches on the front edge of the laptop. Your machine may have something similar.
I dont know what last kernel was that worked, i updated my computers and after the update wireless was broken. [root@thundera packages]# rpm -qa | grep kernel kerneloops-0.12-1.fc10.i386 kernel-2.6.27.19-170.2.35.fc10.i686 kernel-2.6.27.12-170.2.5.fc10.i686 kernel-2.6.27.15-170.2.24.fc10.i686 kernel-firmware-2.6.27.19-170.2.35.fc10.noarch [root@thundera packages]# uname -r 2.6.27.19-170.2.35.fc10.i686 I have no physical kill switch, im running F10 on two Dell Latitude D830 laptops, so the kill switch message makes no sense. Let me know if i can provide more input for fast resolving since this issue is most troubleing.
I see...and what happens when you manipulate the soft rfkill switch that must be somewhere on that box? Also, please ensure that there is no BIOS setting disabling the wireless lan device.
Im sorry, i must be really tired....it works fine for me. I had manually disabled the wifi card and was stupid enough to didnt double check this before reporting! Im sorry again!
Hey, it happens... :-) Andrew, are you still experiencing a problem?
I was, then I read this report this morning and found the mechanical slide switch you mention. I've not seen it before and it looks like due to the dumb positioning of the switch, it's been knocked into a semi-on/off position that disabled RF. Flicking it turned Bluetooth back on. Wifi needed a reboot but it seems to be back now. Thanks for the solution. This bug can now be closed.
