Hi,
On one of my systems running Leap 15.1 I have a weird issue with connecting the system to Wifi networks that I however haven't really been able to pin down precise enough to feel confident in writing a bug report.
When trying to connect to a WLAN after system start the connection will fail and a pop-up will appear that asks for the WPA password. Now, no matter how often I enter the correct password in that dialog, connection will still fail. However, if I cancel the connection, wait for a couple of seconds and then press the connect button in the KDE Network Manger, the connection will succeed, using the password that had been stored for that connection all time long.
Also, if I remove the configuration for the network and connection from the KDE network manger, the password will be prompted in the network selection screen, not in the pop-up window, and connection will work right away.
Weirdly, I only observe this issue on one of my systems. The only thing special about that system is that I messed up when ordering it and it thus is powered by an RTL8821CE-based Wifi adapter which I use via a kernel module ported over from Endless OS [1]. However, as the connection works without issue if "manually" connecting to the network, I fail to see how the driver could be at fault here.
Any idea on what I could look at to further pin down the issue?
Kind Regards, Matthias
