Are you using Network Manager, and if so is NM managing your interface?
1. Is there a nm-applet in the upper panel on the left?

I don't understand either point 1 or point 2; I do almost everything via
the command line in xterm. Could you elaborate?
If you have a /var/run/NetworkManager/NetworkManager.pid file, then
NetworkManager is running. That's probably the most reliable way.
If you're in a GUI, look around in the taskbars and see if there's an
icon that looks like two computers, one in front of the other. Right
click on it and select "About" from the drop-down menu.
If the About box says "NetworkManager Applet", then NetworkManager is
running. If it says "Network Monitor" then NetworkManager is NOT
running. The problem is that the icon for the NetworkManager applet and
the one for Network Monitor are damned near identical. It's caught me
by surprise before.
Thanks for this. I actually understand it!
Good! :-)
There is an icon on the upper panel next to the date which, when I put
the mouse cursor over it, displays the message "no network connection".
As I mentioned in a previous post, the system stopped connecting at
boot, and I got internet connectivity by executing dhclient. Obviously,
that command by itself does not properly set network connectivity and
I have not figured out yet how to fix the broken step in bootup.
Well, we still don't know if it's NetworkManager (NM for short) or if
you're using ye ol' network stuff. My guess is it's NM (the "About"
will tell you).
Clicking 'about' generates a popup identifying NM as Applet 0.7.0.
Well, that settles that! :-)
If it's NM, then make sure "Enable Networking" is checkmarked (right
click on icon). If it isn't then NM won't try to manage the network and
that may be where you're having issues. If it's not checked, right
click on the NM applet icon and left-click on the "Enable Networking"
option. Then wait a few seconds to see if it fires up.
Clicking on enable networking produced an immediate 'Network
disconnected' message. Then left-clicking produced a bunch of
lines that listed a series of network devices (5) that had been
disconnected. All the text is greyed out.
Ok, so right click on the icon and select "Edit Connections". Select
the "Wired" tab (I'm assuming this is a wired connection) and click
"Add". Another window should pop up where you can enter the appropriate
data.
If the window doesn't pop up, then edit the file called
"/etc/sysconfig/network-scripts/ifcfg-eth0". Make sure there's a line
in there that says:
NM_CONTROLLED=yes
If not, add it (or edit an existing line) and try a reboot. See if the
network comes up this time. If not, then you should be able do the
above stuff about editing connections, since NM is now controlling this
interface.
I rarely use NM myself as it has some, uhm, issues if you have a complex
network configuration as I do.
