I installed wicd on VSIDO but now I am not able to figure out how to replace ceni with wicd, to test things out. As of now, both of them, i.e., ceni and wicd start up, and wicd is shut down by the system (I think)....
This may be because ceni writes to the /etc/network/interfaces file while wicd (and gnome's network manager) do not. I'm pretty sure if you edit (as root) the /etc/network/interfaces file and comment out everything but the:
auto lo
iface lo inet loopback
lines (usually at the beginning) then wicd should work.
If you go back to using ceni, you will need to remove the wicd configuration files.
