Description of problem: This is a repost of Bug 572827, which was auto-closed because the original reporter didn't update the version field. The bug still exists. The problem is the RF-Kill switch on Dell Laptops; if it is not turned on before boot then enabling it later does not work. This is what is printed in the logs when the kill switch is first enabled: This is what is printed: [ 265.964504] iwlagn 0000:0c:00.0: RF_KILL bit toggled to enable radio. [ 265.970813] iwlagn 0000:0c:00.0: RF_KILL bit toggled to disable radio. So it is enabled, and then very quickly disabled. Version-Release number of selected component (if applicable): How reproducible: The problem is fully repeatable. Steps to Reproduce: 1. boot with rf kill switch off 2. enable RF 3.
Hmm, does RF kill work if you blacklist dell_wmi and wmi modules.
(In reply to comment #1) > Hmm, does RF kill work if you blacklist dell_wmi and wmi modules. I blacklisted those 2 modules (and checked with lsmod that they did not load). Not only did the RF Kill switch not enable WIFI, the previously working situation (turning on the radio before boot) no longer functioned; WIFI was not detected on the machine no matter what the state of the switch was. Unblacklisting and modprobing those 2 modules resulted in the same state as booting with RF Disabled: two messages from iwlagn about RF_KILL being toggled about 50ms apart.
I'm happy to report this is now working in F15... Closing the bug
