Description Jan Stodola 2021-01-12 14:02:29 UTC 
Description of problem:
The list of available Wi-Fi networks is sometimes empty after clicking the "Select network" button, although Wi-Fi networks were available/displayed before. See steps to reproduce.

Version-Release number of selected component (if applicable):
anaconda-33.16.4.5-1.el8

How reproducible:
Always

Steps to Reproduce:
1. Installation started from boot.iso on a USB drive.
2. Proceed to the Network spoke, select the wifi device and click "Select network".
3. Select one of the networks protected by a password, click "Connect", but do not enter any password and click "Cancel".
4. Click on the "Select Network" button again (do it quickly).

Actual results:
The list of available wifi networks is empty.

Expected results:
The list of available networks is populated.

Additional info:
Workaround is to wait a while and click the "Select network" later (in  about 10 seconds). Perhaps there is a refresh of the available networks happening at this time?

Comment 3 Jan Stodola 2021-01-19 17:21:54 UTC 
The same problem with empty list of wifi networks happens right after enabling the wifi device. There is no info if there are no networks available or if scanning is in progress.
Comment 4 Radek Vykydal 2021-01-20 09:45:45 UTC 
I noticed that this is also a problem in installed system environment GUI: top panel -> Select Network GUI dialog. When I was testing the patches running Anaconda on installed system (F32) the behaviour in this aspect seemed the same for the system dialog and for Anaconda dialog so I think the root cause is on NetworkManager scanning the networks / APs ?
Comment 5 Beniamino Galvani 2021-01-20 15:52:13 UTC 
NM doesn't scan while it's connecting to a Wi-Fi network, so after the activation is canceled, you have to wait for a new scan to get the updated results. However I expect that the APs that were detected before would stay in the list for a certain time (at least a minute).

> There is no info if there are no networks available or if scanning is in progress.

This seems more like a GUI problem.
Comment 7 RHEL Program Management 2022-07-12 07:27:28 UTC 
After evaluating this issue, there are no plans to address it further or fix it in an upcoming release.  Therefore, it is being closed.  If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened.
