    Is this maybe a firewall issue? Or if you have SELinux enabled.

    Also, to connect to WPA encrypted networks, you may need to install and configure wpa_supplicant first. This is why I stick with distros that have the NetworkManager application. It make wireless soooo much easier.

    Thanks for your reply,
    but, no. I don't have SELinux or any firewall enabled.
    Very odd that this is happening. I was thinking about using network manager, too. Only thing is that it's a tray icon application and Gtk. I am using enlightenment as my wm and it wouldn't really fit, plus I have to deal with keeping it minimized all the time.
    btw,
    I am getting errors for nm-applet:
    Code:
    $  nm-applet
    ** (nm-applet:6894): WARNING **: <WARN>  nma_dbus_init(): could not acquire its service.  dbus_bus_acquire_service() says: 'Connection ":1.30" is not allowed to own the service "org.freedesktop.NetworkManagerInfo" due to security policies in the configuration file'
    I guess I'll check the configuration file ...

    Thanks again,

    That error is similar to one that struck Fedora, after an update. Read the thread about it here;
    http://www.linuxforums.org/forum/red...top-error.html

    Fedora released update fixes for most of it, but I still had to edit the /etc/dbus-1/system.conf file, as suggested in the link posted by devils casper.
