Is the router running DHCP (i.e., is it assigning
the IP addresses to the computers on your
network) or is your linux box?

If any of your client PCs are running windows,
you can run winipcfg or ipconfig to show gateway
and other ip information. Somebody else already
mentioned the linux way. (route -n)

To set the default gateway for my client PCs
via DHCP from my redhat box, I have this
line in my /etc/dhcpd.conf file:

option routers 10.0.0.1;

But if your linksys is providing the DHCP,
you will probably have to configure it to
tell your network that it is the gateway;
and I have never used a linksys router.
