    That wouldn't surprise me but the install told me that it was 
replacing necessary files. I assumed the old settings would be amongst 
those.

    I guess it's running.

    I've never looked. I figured that if it wasn't working then I'd know 
without checking the light =).

    I don't have a 'network-manager' there, only a 'networking' entry. 
Is that the same?

ken at Epona:/etc/init.d$ ls net*
networking
ken at Epona:/etc/init.d$

    Yep. The applet is in the top bar and I've used it to set what I 
thought were the correct settings as previous, but no success.

    Not a priority <g>.

    Now that I'm in Windoze I can have a look for it. Dunno it it will 
be more suitable than the standard installation, but it can't hurt.

    If it's any use, this is the result of stopping & starting the 
init.d/networking command:

root at Epona:/etc/init.d# ./networking stop

    It make little sense to me, except to indicate that something's not 
working as I wish it to.

Thanks for taking the time to help,
It's much appreciated.
