Today I installed Fedora13 with LXDE desktop from a live version on a USB stick onto my Samsung USB hard drive. Worked very well.
I got good connection to my WLAN as long as I denied to enter a password for a security applet which seems to store the password for the network.
Since this denial required that each time I connected to the WLAN I had to enter my WLAN WEP password; which is a bit unconfortable; I finally entered a password;
since then I am not required to enter my WLAN password; the WLAN password appears correctly in the network manager but my system does not anymore connect to the WLAN.
For this thread I booted into Mandriva and everything works fine that is good connection to my WLAN and the internet.So, the error is definitely at the side of Fedora13.
Any suggestions what is wrong and how to repair it?

Can you delete existing and create new connection? Or maybe another without storing password?

Have you visited bugzilla to see if your problem is already recorded?

recofigureing the connection did not work
I don't know how to get rid of the "Schlüsselbund" features of fedora13. I am the only user of this netbook. I don't need a password to reach my stored passwords. The system should access them directly.
No, I have not looked into bugzilla; I assume that is a fedora13 problem, since I never had that with fedora 11.
So my problem remains UNRESOLVED
Still no WIFI problem with Mandriva. Maybe I should go ahead with them and reenter to fedora when a new version arrives.

As you wish. No one will even try to force you to use your brain to resolve this issue.

Since I do not get useful information from this forum either since there is no useful information or since I am the only one experiencing this problem well I close this case.
Maybe another fedora package in future will suit better to my netbook and its outfit.
Good bye
