*** Bug 1049500 has been marked as a duplicate of this bug. ***

I've looked at this bug into more details, getting information from dcbw as well.

1) Can you rename the bug to "Dynamic WEP"? I looked for "wep enterprise" and could not find anything related to that. dcbw explained that it was "Dynamic WEP", for which I was able to find information.

2) The bug is marked as a regression. From which product/version is that a regression? How did it work in that version?

3) 
> every time I create wep enterprise profile it switches back to key management.

- How do you create the profile?
- Can you explain the exact steps in the UI?
- Do you click on the gear button in the list of APs and modify the settings by hand? (in which case, I don't need access to the AP to verify that the values are saved correctly)

Can you answer the questions in comment 12 please?

I'll reassign to NetworkManager for now, because it doesn't work in nm-connection-editor either, which gnome-control-center's Network Security pages are based on.

*** Bug 1359183 has been marked as a duplicate of this bug. ***

I have been able to reproduce the issue in this way:
1) Choose a WEP or WPA-PSK protected WiFi network from gnome applet
2) When prompted for the key just cancel
3) Then change the connection in gnome-control-center as per Vlad settings (change it to Dynamic WEP (802.1X))

If you now check the connection (nmcli c s) you will see that the settings have not been changed.

If you try to perform point 3) with nm-connection-editor, it works.

If you open it after the change with gnome-control-center, you will se all the option correctly but any change in any option (e.g., the identity field) will not be saved.

So, I will reassign the bug to gnome-control-center for further investigation.

I cannot find a version of RHEL where dynamic WEP works properly. I also could not setup an Access Point locally to debug this problem.

Given that dynamic WEP is a very niche setup, I'll punt this to RHEL 7.4, which would hopefully come with an updated control-center package, and focus on fixing the problem upstream.

Removed the regression keyword.

FWIW, upstream bug was updated:
Retitling. I discussed "Dynamic WEP" support with Cisco and it is not supported by the latest APs or other network hardware they ship.

https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-3/config-guide/b_cg83/b_cg83_chapter_01010100.html#ID957

"Dynamic WEP encryption method is not supported. The last release to support this method was Release 7.0 "
Last 7.0 releases were in 2011.

This type of authentication works under RHEL 8.1.

See: http://beaker-archive.host.prod.eng.bos.redhat.com/beaker-logs/2019/06/36360/3636057/7061809/95523427/437461827/report_control-center-wireless-display_Test016_gcc_wifi_wep_ttls.html

It will be checked under RHEL 7.7 as well.

TEST SETUP
Distro: RHEL 7.6 Released
Component version: control-center-3.28.1-4.el7

TEST PROCEDURE
1. Install distro RHEL 7.6 on a physical machine in our wireless lab.
2. Run the following automated test:

  Scenario: Wi-Fi-sec - configure and connect WEP-TTLS profile
    * Start gnome-control-center via command in session ... passed in 10.230s
    * Open section "Wi-Fi" in settings ... passed in 4.691s
