Description popov895 2020-07-13 18:21:08 UTC

SUMMARY

Currently, the NetworkManager applet refreshes the list of WiFi networks every 10200 ms (~10 sec), but sometimes you need to refresh it immediately because you know that a new network has just appeared. I can manually refresh the list using command `sudo iwlist device scan`, but it would be great to be able to do this from the applet. Every mobile device has this feature, also there is an extension that adds this feature to the GNOME.

SOFTWARE/OS VERSIONS

Linux/KDE Plasma: KDE neon 5.19 User Edition
KDE Plasma Version: 5.19.3
KDE Frameworks Version: 5.72.0
Qt Version: 5.14.2

We currently scan right after the applet is opened and if that request fails, then we try every 2 seconds until we get a successful scan and then every 10 seconds, which is the treshold NM allows us to request a scan after previous one. This means there shouldn't be need for the button to refresh the list manually.

And yet we keep getting user requests for this anyway...

I understand why is that. You don't see the scan happening in the background and you want your AP to appear as soon as possible. However, the way it is implemented now, you will actually get it as soon as possible. You might just think it was because you pressed the button.

Comment 4 popov895 2020-07-15 09:00:51 UTC

I didn't know that the implementation of this feature isn't possible due to the limitations in the NetworkManager. It's sad.

Why don't you scan when the applet isn't open? At least you can check that the user isn't connected and scan even if the applet is closed.

Maybe that's something we can communicate to the user? Like perhaps we could add a spinner to the applet while the scan is still happening.

...As requested in Bug 421370, in fact.

Comment 7 LuneLovehearn 2023-09-28 09:09:46 UTC

I was about to write a new bug tracker about this but anyways.. that button should be there so users can refresh the list, or show a way that it is looking/scanning for networks, making it more intuitive.
