What brand/model of wireless router? I failed to get a dlink working, 
though I've had n problems with Apple's airports or a linksys.

I don't use the builtin dhcp server, but I do use dhcp.

to edit the files with a little vim, but I prefer to see something to

If the system hibernates, then it should resume to the same state it was 
in before. By definition.
