Description of problem: The NetworkManager applet in gnome-shell sometimes fails to display all available wireless networks. In some cases, the only one that displays is the one you are currently associated to and no "More..." item appears. In other cases, there are a couple in the "More..." list, but they appear to be Ad-Hocs only. The other infrastructure ESSIDs do not show up. As a separate (but perhaps related) problem, the Wireless On/Off switch doesn't appear anymore either. As a result, I cannot connect to these other wireless networks. Version-Release number of selected component (if applicable): NetworkManager-0.9.0-2.fc16.x86_64 gnome-shell-3.1.91-2.fc16.x86_64 wpa_supplicant-0.7.3-11.fc16.x86_64 kernel-3.1.0-0.rc6.git0.3.fc16.x86_64 How reproducible: not sure Steps to Reproduce: 1. Unsuspend laptop 2. Wait for network to connect to pre-configured wifi network 3. Pull down network applet menu and notice that other ESSIDs don't appear 4. Run "iwlist scanning" from a root shell Actual results: Some ESSIDs appear (perhaps only the one you are associated to plus any AdHocs nearby), but other Infrastructure ESSIDs are missing. I'm connected to WPI-Wireless, a WPA2-Enterprise connection with EAP-TLS certificates. This connects automatically and also shows up in the list with a bullet next to it. Here is what I see: Wired cable unplugged Wireless unavailable *WPI-Wireless (5 bars, lock icon) More... Printer (adhoc icon, lock icon) iwlist scanning shows more ESSIDs/APs available than show up in the applet menu.

Run 'nmcli dev wifi list' or 'nm-tool' that will tell us what SSIDs NetworkManager is aware of. If that shows networks that are not visible in the GnomeShell network indicator, then the indicator is probably misbehaving. Otherwise there could be a problem with scanning via wpa_supplicant.
Seeing this here, too, gnome-shell-3.2.1-2.fc16.x86_64. Looks like there's some problem in the communication between Gnome Shell and NM. Typically, the list of networks in the Gnome Shell panel menu is incomplete or incorrect after: - suspend/resume cycle; - turning wireless of and back on. Restarting Gnome Shell correctly repopulates the list. In my case, at the moment, nm-tool reports 6 wireless access points (as it should). However, only one of them shows up. Was not a problem with Gnome 3.0. Have filed an upstream report at https://bugzilla.gnome.org/show_bug.cgi?id=666151

This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '16'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 is 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" 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: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
