screenshot of NM not displaying networks

This is a screenshot showing how in F15 I can not see any wireless networks eventhough wireless card is on.

If I try to manually connect to my wireless network entering the SSID in Network Settings -> Wireless, right after I type in the WPA2 key, the nm-applet dies.
NetworkManager keeps running.

The same laptop running F14:

nm-applet tooltip showing connection to a wireless network

The screenshot shows that, in F14 with the same hardware, I can connect to my home wireless network.

Could you run in terminal
$ nm-tool
which would show us if NM can see some WiFI networks?

This is from F14 working and connected:

  Wireless Access Points 

I am seated in the very same spot, no walls, AP is at like 1.5 mts from the laptop...

It doesn't show any networks because it's disconnected.

Please try to scan with:
sudo ifconfig wlan0 up
iwlist wlan0 scan

And grab /var/log/message so we can look at NetworkManager logs.

In comment #3 you say that applet dies. Do you see any crash in abrt or something in .xsession-errors or whatever?

Well, the card is up, but here it goes anyway,,,

[liveuser@localhost ~]$ su -
[root@localhost ~]# ifconfig wlan0 up
[root@localhost ~]# iwlist wlan0 scan
wlan0     No scan results

funny... now it sees the network... I will try to connect and get back to you.

Curious: is it necessary to do all that ifconfig/iwlist stuff to get it working?

It can not connect: asks for WPA pswd, and then, it asks it again, and again, and again...

I'm having the same issue with my Acer 3100 laptop (with AR2413 chip).

Same issue here with Dell M1330, Intel 4965 AG wireless card. F15 Live Beta

'nm-tool' shows nothing under Wireless Access Points
'iwlist wlan0 scanning' shows many networks detected

Also, if I click on the NetworkManager icon and just leave it up, the Wireless section will intermittently switch between the On/Off slider and "unavailable".

Danny, in your case there is a problem with wpa_supplicant. It crashes continuously. abrt has caught the crash. Would you mind running 'abrt-gui' as root and file the bug?

What version of wpa_supplicant do you have?

Sorry for this bug-jacking... I added my comments to a different bug which looks similar.  https://bugzilla.redhat.com/show_bug.cgi?id=697946

wpa_supplicant version v0.7.3 (using LiveCD)

I was also asked to run abrt-gui to report the bug, but unless I'm missing
something, no application crashes are being captured - even though I can still
watch the wireless go back and forth between slider and unavailable.

I am having same problem.  Acer Travelmate 2423WXCi with Atheros wireless card.  Does not show any networks in Fedora 15.  When attempting to manually add the wireless network, the applet crashed.  The wireless worked fine in F14 and works fine in Ubuntu 11.04.

Forgot to include, my wireless card is the same as everyone else with this issue in this report so far... AR2413

06:05.0 Ethernet controller: Atheros Communications Inc. AR2413 802.11bg NIC (rev 01)

Does anybody see 
"ath5k phy0: gain calibration timeout .." in dmesg?
That would indicate the issue described in bug 672778.

If you say that applet crashed, can you see/report that from abrt-gui. Any interesting logs in /var/log/messages and ~/.xsession-errors ?

Hi,
"ath5k phy0: gain calibration timeout .." is not in /var/log/messages.

I can not confirm that the applet crashes. For me it seems that this is a kernel or NetworkManager issue since in Ubuntu 11.04 BETA this did not work either. I'll download the latest Ubuntu 11.04 iso-image and see if this works not there.

In my messages-logs it says that device is disconnected (grep NetworkManager):

Maurice, in your case WiFi is disabled. Please check with
$ rfkill list

And try enabling with
$ rfkill unblock all
And be sure, you don't have WiFi blocked by a hardware switch.

The problem in this bug is probably driver. All who has a problem, please experiment with different kernel versions.

Jirka, I just got to thank you for this suggestion, it solved my nagging problem.

Really appreciate your help,

Did I say thank you?

Thanks

This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:
