Description C Sand 2009-07-10 05:38:39 UTC 
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):
0.7.1-1.fc10.i386

How reproducible:
always

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
  
Actual results:
Says that "wireless is disabled"

Expected results:
Allow wireless connections

Additional info:
Fresh Fedora 10 install (default options), with updates as of 10 July 2009.
Linux kernel 2.6.27.25-170.2.72.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.

/var/log/messages also shows up a few interesting tidbits:

What's the output of "rfkill list" on your machine?


Bug report on the kernel butracker:

Comment 5 C Sand 2009-09-16 08:44:11 UTC 
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
Comment 6 Dan Williams 2009-10-16 20:54:38 UTC 
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!
