[Dmitry K.]

hardware: Acer aspire 5920g with Intel(R) PRO/Wireless 3945ABG/BG

Plasma widget networkmanager requesting wpa-psk password again and again.

On logs i found:

Possable, this duplicate.
I also use 64-bit version kubuntu 9.10.
But my AP configured for WPA/WPA2 encryption with ASCII passfrase.
Translation passfrase dont help me.

Unless/Until someone marks this as a duplicate, I added this post this morning to the other bug thread on how to gain wifi back. Unfortunately you lose knetworkmanager and the plasmoid applet but you should atleast have wifi (which I personally can't live without on my laptop).

Sorry. I not use knetworkmanager. I use plasma widget for network manager.
And on Kubuntu 8.10 and 9.04 all works fine.

[SRElysian (srelysian)]

knetworkmanager and the plasma widget both seem to be using the same back-end system which doesn't work properly at current. Like I said, follow that link and try using wicd, if it doesn't work for you, your problem might be completely different. I tried both the plasma applet and knetworkmanager. Neither of those would allow me to connect to a secured wireless network, wicd connected just fine.

[SRElysian (srelysian)]

On a secondary note: the plasma widget and knetwork manager worked for me on intrepid, and jaunty.. as well as karmic until i added "pre-released" and "unsupported" repositories in order to play with KDE 4.3beta. So it seems to me that the back-end for knetworkmanager and the plasmoid broke in 4.3 beta specifically.

I install wicd now and it not work also :(
