kubuntu-users Digest, Vol 64, Issue 18

My wired and wireless problems are fixed- it took drastic measures.  I 
have been
dealing with connection problems on my laptop since Kubuntu 9.04 and 
9.10 (no
problem with 8.04, 7.10, 7.04, & 6.10) my ethernet and wireless 
disappeared and
fixed by reinstalling. They both worked for a short time with 10.04 then
disappeared. I completely removed nw-manager and installed "wicd" which 
fixed my
ethernet. Then the da*n keyring blocked wireless.  I even changed the 
key in my
router then attempted to change the key in Kubuntu - the old key stayed and
refused to record my new key -- sooo fixed it.  The fix worked for both 
Kubuntu
and Gnome Desktops.

This is how I fixed the problem. I fired up Synaptic Package Manager and
reinstalled wicd, wpasupplicant, kwalletmanager, laptop-detect, and wireless
tools (Note: there may have been some others that I forgot about)-- then, I
rebooted. It has worked like a charm for two days -- your mileage may very.

I hope this helps someone.  It worked for me.

Blessing,

Jon Piper

But it certainly seems to me that once you have a connection set up with NM, doing any editing of it (including typing in passwords) is likely to cause that connection to break. I tried wicd but it doesn't do 3G connections, which is a bit rubbish.
