NetworkManager mis-detects RF kill switch (doesn't allow wireless connections with Intel 5100)
Last modified: 2009-10-16 17:00:19 EDT
Description of problem:
NetworkManager doesn't allow wireless connections even though the hardware is detected by the Linux kernel. The hardware in question is "Intel Corporation Wireless WiFi Link 5100", inside a "Dell Vostro 1320" laptop. Wireless is enabled via a switch (i.e. no RF kill).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Enable wireless via switch (i.e. no RF kill)
2. Boot Fedora 10
3. Login to Gnome desktop
4. Click (left mouse) on the NetworkManager icon in the top panel
Says that "wireless is disabled"
Allow wireless connections
Fresh Fedora 10 install (default options), with updates as of 10 July 2009.
Linux kernel 18.104.22.168-170.2.72.fc10.i686 #1 SMP
See also the attached output of dmesg, lspci and ifconfig.
Interesting section in dmesg, even though the RF kill switch is off (ie. wireless enabled):
iwlagn: Radio Frequency Kill Switch is On:
Kill switch must be turned off for wireless networking to work.

What's the output of "rfkill list" on your machine?
Bug report on the kernel butracker:
The machine is my mum's laptop, on which I have since installed an old-ish Ubuntu (8.04). I have only intermittent access to the laptop.
If "rfkill list" from Ubuntu 8.04 would help solve the problem, I'll report the output. Otherwise the laptop isn't likely to have another OS (e.g. Fedora) installed on it in the near future.
I'd venture the problem with the wireless connection lies in the bug shown in Comment #2
Ok, I'd need the laptop with fedora to debug further, but I believe this issue is either fixed upstream or in F11, or is a HAL problem deeper down with rfkill. Thanks!
