This should be easy and I know I have gotten it working before, but I'm stuck.

I plugged the ethernet cable in before booting, but when I try to ping the router I get "Network is unreachable".

If I say ifconfig -a I get a list of interfaces including eth0, and it's shown as UP BROADCAST RUNNING etc. etc.

My /etc/network.conf has INTERFACE="eth0" and DHCP="yes" and STATIC="no".
I guess these may not apply to DHCP, but NETMASK="255.255.255.0" and GATEWAY="192.168.0.1" and DNS_SERVER the same. I checked the router with another computer and that's the right gateway address.

I clicked the Start button in netbox and it goes gray for several seconds, but there seems to be no effect.

Thanks in advance!
