I'm not CERTAIN I know what you're describing but I had a similar
problem a few weeks ago with my router (netgear appliance kind), and I
just had to redo some of the settings and the machine's address works
great now.

OH and you aren't the only one who has noticed something different...


I know very little about networking. Maybe check your DHCP server and
see how it has been configured to identify your attached equipment.
Does it assign an address based on the MAC address of the network
card, or does it look at the name the computer calls itself? I bet the
computer looks different from the router's vantage than the slackware
/ windows setup did.

I have also noticed that the network connection is "touchier" when
it's coming up than under previous OSes. I have a similar problem with
a networked laser printer, and my solution on both has been to move
the network cable to an old, slow ethernet hub on the theory that it
was trying to negotiate at 100 Mbps but there was a kink in the cable
or something that made it only suitable for 10 Mbps. But that was just
a theory and what I REALLY ought to do is try a new cable to see if it
works better.

Now I'm just rambling so I hope I have a germ of a solution in there
