I have an old laptop with an internal and external USB wifi adapter. - Click on the applet and see both devices, each with a list of available networks. - I click on a network under the USB device, a "Wi-Fi Network Authentication Required" window appears with the wrong device selected. - Click on the device name and change to correct device and the password entry disappears - Change back to original (incorrect) device, password entry still gone. Can't do anything but hit cancel. This worked on Fedora 27 (1.8.4-1), fails on Fedora 29 (1.8.18-2).
