I have a wireless network in my home, using a Linksys wireless router,
which is located in my basement.  I have a few computers on the 2nd
floor that use this wireless connection for Internet and file-sharing.
The wireless network is fine for internet use and most file transfers,
but large transfer are much slower than I'd like.

I'm trying to setup a wired network between the 2nd floor computers, to
allow for faster file-transfers, while maintaining their connection to
the wireless network, but they do not seem to be able to communicate on
the second, wired network.

I'm starting with two PCs, each running Windows XP Professional, setup
as follows:

Computer A:
Wireless NIC:  Static IP: 192.168.1.5;  Subnet: 255.255.255.0;  Default
Gateway: 192.168.1.1
Wired NIC:  Static IP: 10.0.0.1;  Subnet: 255.255.255.0;  Default
Gateway: n/a

Computer B:
Wireless NIC:  Static IP: 192.168.1.6;  Subnet: 255.255.255.0;  Default
Gateway: 192.168.1.1
Wired NIC:  Static IP: 10.0.0.2;  Subnet: 255.255.255.0;  Default
Gateway: n/a

If I try to ping 10.0.0.2 from computer A it times out, though I can,
of course, ping 10.0.0.1.  The same situation occurs with computer B.
I've tried two different switches and multiple cables to confirm that
it's not a hardware issue.  Will Windows not allow me to run these
machines on a separate network?  Is there something I'm missing?  I've
done much searching online, but cannot find any help.  I would
appreciate any insight.

Your settings looks OK and that should work. Posting the routing table here may help. To do that, run "route print".

Thank you both for taking time to respond to my posting..

I've double-checked and have confirmed that I have no firewall running
on either system.  I ran "route print" on both systems and pasted the

firewall program is blocking access on the wired network because it
doesn't recognize 10.0.0.x as a range of trusted IP addresses.

When you want to access a computer using the wired network, use the
wired IP address.  For example, to access shared folders on Computer B
from Computer A, type this in the Start > Run box on Computer A:

   \\10.0.0.2
