Slow WiFi initialization on KDE Plasma

Network Manager applet fires up with a 20 to 30 seconds delay after Plasma Desktop 5.9.4 has loaded. It then starts searching for available wireless connections and eventually connects to one. Is there a way to get WiFi to initialize right away after Plasma has loaded?
Wireless network card is Broadcom BNC4352

Do you have this set up as a user connection (which will only be invoked after logging in to KDE) or as a system-wide connection (“All users may connect to this network”), which will be activated as soon as NM is up and running?

I have tried both ways, all users, and single user. rebooted and same results.

To me it seems that NM itself is starting with a considerable delay.

And did you store the password system-wide too? (click on the disk symbol in the password input field on the Wireless Security tab to configure that)

If not, NetworkManager cannot actually connect before the user logs in and there’s basically no change at all.

incredible. saving password (un-encrypted) for all users, as you advised, fixed the issue. now the network manager is starting right up and is searching for available networks. internet access is available in max 5 seconds after plasma desktop is loaded. this, even without checking the option to allow all users to connect to this network.

I should have mentioned that to you as well. That’s how most of my connections are set up. Anyway, glad to read NM is working as you wanted now. :slight_smile:
