OK, I understand. Now we need even more info. Did you use the orinoco
card to do the install or was it eth1? I suspect eth1 might be an IBM
internal Wireless interface.

At a console prompt do
lspci -v
Be sure the orinoco in plugged in when you run that.
That will tell us what the Network interfaces are. They work in windows so
we have to find out what they are. We need the lines like these from
my T40.
0000:02:02.0 Network controller: Intel Corp. PRO/Wireless LAN 2100 3B
Mini PCI Adapter (rev 04)

Most (all) IBM interfaces will work in Linux so you need to know what
modules have to be loaded before bringing the interfaces up.
As I said, I don't use Gnome or KDE, so I can't help you there. If we
can get the network working without them, _they_ should just fall into
line. I hope.
Install the debian-reference package. Chapter 10 is the section you
need to read through.
Another thing to check. Make sure you have the dhcp3-client package
installed in both the etch and testing installs.
