Hello,

I want to connect a PC (Debian Sarge) and a laptop
(Ubuntu Edgy with network manager),
via a ethernet cable. Each computer have a wireless card working properly.
I connected the two computers using the cable with success by modifying the
/etc/network/interfaces files on both, the laptop:

auto eth0
iface eth0 inet static
address 10.10.10.1
netmask 255.255.255.0
gateway 10.10.10.2

and and the computer with Debian:

auto ath0
iface ath0 inet static
address 10.10.10.2
netmask 255.255.255.0
gateway 10.10.10.1

The problem is that the wireless no longer have access Internet; this
occurs in the two computers; However, both can see the available wireless networks on the LAN and ping well to my desktop computer. When I unplug the cable, the two wireless work fine again.

Can I connect the two computers this way while having a Internet connection with the wireless? and if so, How would I do that?

Best regards and thanks in advance for your response,
Héctor.

You'll probably need to edit the routing tale on your system (with the route command) to make sure the default route is going over the wireless.

Set the gateway on the two wired nics to the same one the wireless uses
