I have freshly installed archlinux with Gnome3 on my Dell Inspiron 1520. I am using b43 broadcom drivers since my wifi card's pcid is 14e4:4312.

When I installed NetworkManager(with gnome keyring) it sees all the available Wifi Connections, but whenever I click on a encrypted connection it first asks for Admin Authentication(On the very first try), then proceeds to disconnect and automatically connect to the first available non encrypted connection.

Is there something that I haven't installed and/or configured?

Here is the log

Solved it, didn't have network-manager-applet installed.

Got answer from the archlinux forum

When nm-applet starts, it registers itself with NetworkManager as a "secret" agent. When NetworkManager needs to ask for a password, it asks the agent to interact with the user.

However, it wasn't working on my Arch system:

$ pacman -Q network-manager-applet 
network-manager-applet 0.9.8.0-1

I compiled nm-applet from Git (nma-0-9-8 branch, commit 742e5daf91) and that worked.
