<div dir="ltr">NetworkManager used to work fine for me but during the last few installations its a big hurdle in the wireless connectivity.<br>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.<br>
The error which I recieve upon logging into the gnome is:<br><br>"The NetworkManager applet could not find some required resources. It cannot conitnue".<br><br>But still, there are no errors in the syslogs besides the below ones particularly <i style="color: rgb(102, 51, 255);">"localhost NetworkManager: <WARNING>
nm_device_802_11_wireless_scan (): could not trigger wireless scan on
device ath0: Network is down</i>". <br><br>Thanks in advance for the helpout.<br><br><br><br><br><br>[root@localhost abbask]# grep -A 2 -B2 NetworkManager /var/log/messages | tail -60<br>Jan 15 05:35:31 localhost NetworkManager: <information> Activation (eth0) Stage 1 of 5 (Device Prepare) started... <br>
