Description Oliver Haessler 2018-02-15 09:14:09 EST
Description of problem:
In RHEL 7.5 Snapshot 3, if the Gnome control center is opened on the WiFi Tab, and stays there, the list of available networks is not shown after some time, and on the current connected wifi network is shown.

based on https://bugzilla.gnome.org/show_bug.cgi?id=767918

NM upstream would like to reduce periodic scanning, and that means that clients should start implementing scan requests themselves while their wifi lists are open if they use that model.  Similar to how the Windows and macOS WiFi lists update themselves when they are open.

Once enough clients have been updated (eg, nm-applet, gnome-shell, KDE, geoclue, etc) we can reduce periodic scanning in NM itself.

This needs to be added also to Gnome control center.

Please make sure this is included into RHEL 7.5, as it impacts users trying to connect to Wifi networks.
Comment 2 Bastien Nocera 2018-02-20 10:20:26 EST
The requirement is new due to NetworkManager 1.10 being used which includes the following change:
* Background scanning is now disabled for non-WPA-Enterprise Wi-Fi networks.
Comment 4 Vladimir Benes 2018-02-20 10:32:31 EST
Could we at least scan when we open the Wifi panel? Isn't this doable for 7.5? It's really embarassing to turn off/on wifi to see available networks.

Working well, thanks!!
Comment 10 Tomas Pelka 2018-02-22 09:00:56 EST
OK I find out that for me it was caused by autoconnect. Autoconnect on RedHat (with always ask password) actually cause that no other networks are visible in the list. Filed another bz - https://bugzilla.redhat.com/show_bug.cgi?id=1548000
