[SLUG] help! resetting nm-applet on Hardy Herron to make wireless work again

["Amos Shapira" <amos.shapira@xxxxxxxxx>]

Hello,

Yesterday I visited a site where I couldn't make Ubuntu 8.04 on my
laptop accept the WiFi pass key. During the tweaks I made to try to
make it work I also clicked off the "Enable Roaming" and other stuff.

Now that I'm back at home nothing I do would convince NetworkManager
to connect to my local WiFi. I enabled roaming back again but all I
see then I click on the left mouse button is "Wired Network" grayed
out (possibly because there is no connection on the wired network),
"VPN Connections" sub-menu and "Manual Configuration", and when I
click on the right mouse button I get "Enable Network" checked.

"Manual Configuration" only gives me the usual "Enable Roaming" option
for both wireless and wired networks, which doesn't seem to make a
difference?

How can I reset NetworkManager to the way it worked before?

Note that I don't want to loose the three network pass keys I have
saved for the networks that used to work for me before this incident.

Thanks.
