In desperate need of help...

[robertfischer89]

There is normally a set of bars (very similar to signal strength bars on a cell phone) in the lower right hand corner of my desktop, from which you can view and connect to available networks.
I currently do not have this set of bars, and consequently cannot connect to a network. I had to get on my Windows partition (which I am on right now) so that I could even get online to post this thread.
I run Fedora 12 with KDE, if that helps. I've made no changes that I'm aware of.
If anybody could please tell me how to either manually view and connect to networks, or get my bars back, or both, I would GREATLY appreciate it... 99% of what I do requires an internet connection, so not being able to access the internet from Linux really throws a wrench in the works.
Thanks much!

Hello. You're saying that you had internet connectivity prior to this and it suddenly and without warning disappeared?

And are you saying the networkmanager (the set of bars in the panel) applet is missing? If that's the case, hit ALT+F2, and into the popup type nm-applet. (It's been a while since I've used networkmanager, but I believe that is the name.)

Have you installed any update recently? What type of Internet Connection do you have?

nm-applet is the correct executable for Gnome NetworkManager Applet, but it's a Gnome thing. I think the KDE equivalent is knetworkmanager. I use Gnome, the default Fedora desktop manager, so I can't help much with KDE components. I THINK there should be an /etc/xdg/autostart/kde4-knetworkmanager-autostart.desktop file that controls autostarting it. If that's missing, the default one is in /usr/share/autostart (from looking at one of my F12 machines that has KDE installed but not in use).

If the KDE network manager is installed, ther should be an entry in the DE start menu. KDE Start > Applications > System > Desktop Applet > Network Manager.

Once you have started it from here, you normally don't need to go back into the menu each time. Instead, there will be an icon in the applet tray that is grey when there is no connection and green when you are connected. The green icon will be replaced by the bars you referred to when you have a wireless connection. When the icon is grey, you will need to click on it to get the list of connections.

Just resolved a semilar problem. There seems to be a conflict between the use of IPv4 and IPv6 lately in Fedora12. (After updates) You can try to disable IPv6 and see if it works. Have clue how this problem started, and neither have other experts I talked too.

Looks like you have plenty of help and I use Ubuntu with Gnome so my situation is quite different, but I prefer using wicd. It does require GTK so take that into consideration.

with a quick google search I found instructions for installing it on Fedora 10. You may find something closer to your version if you look a little further.
