WLAN/Network-Manager broken after system crash

[quadmo]

Hi,

This morning i had a system crash while the network-manager was trying to connect my wlan to the internet.
before the crash, wlan and the network-manager worked fine!

Now, after a restart, when i try to connect to the internet, the network-manager asks me for my WPA-PSK key (often two times) and then says: connection failed!
I have tried this now 20 times... I have restarted the network-manager, i have reinstalled the network-manager, but nothing has changed.

Any ideas??
Thx

Thank you for the info. I will hard-code my network settings soon, to not have this trouble anymore...

By now i have fixed the problem:
Some days ago i have disabled the KDE Wallet Manager. Everything went fine, until the crash...
Now i have enable the wallet again, and suddenly the NetworkManager accepted my Key?!?

I dont really see the reason, but i am connected again :D

KDE Wallet Manager stores passwords - if you disable it, the stored passwords will not be retrieved when needed. When you enabled the wallet again, the passwords are available.

Glad you got it working and the article helps.
