NetworkManager used to work fine for me but during the last few installations its a big hurdle in the wireless connectivity.
I'm using Madwifi and its interface is correctly listed and working but I cannot connect to any wifi AP without NetworkManager. I've two interfaces: eth0 and wifi0. Starting NetworkManager doesn't show any notification icon in the top right in gnome and I believe its only activating the ath0 instead of wireless interface wifi0 but still I am unable to see any of the notification icon in the gnome as I was used to in past for any of the NICs.
The error which I recieve upon logging into the gnome is:
"The NetworkManager applet could not find some required resources. It cannot conitnue".
But still, there are no errors in the syslogs besides the below ones particularly "localhost NetworkManager: <WARNING> nm_device_802_11_wireless_scan (): could not trigger wireless scan on device ath0: Network is down".
Thanks in advance for the helpout.
