no network when installing

I'm trying to install Gentoo, but I cannot ping anything after I get into the Live CD.

I have my PC connected to a router. I also have another PC connected to it where I installed Gentoo with no problem. DHCP worked for it, but not for this new PC.

The new PC has a onboard nVidia ethernet controller.

When I do "ifconfig eth0" I get "Link encap:UNSPEC". When I do "ifconfig eth1" I get "Link encap:Ethernet HWaddr 'mac addr'". So I assume eth1 is the one of interest.

The ip address of my router is "192.168.2.1". I tried the following manual settings:

My IP address : 192.168.2.33
Netmask: 255.255.255.0
Broadcast: 192.168.2.255
Gateway: 192.168.2.1
Nameserver: 192.168.2.1

I used ifconfig and route to setup and also tried net-setup.

I cannot even ping my router, 192.168.2.1, I get "Destination not reachable".

Can someone help?

i'll try that, but I believe there would be lots of output to post. I would have to type in the output on a another computer.

Is there anything in particluar I am looking for?

If the card was not recgonize "ifconfig" would say "error fetching interface information: Device not found"

Thanks

please try following command if you have not tried it so far :-

route add default gw 192.168.2.1 dev eth1

This should sort your problem.

Do you use dhcp? In that case have you tried dhcpd eth0 ? or the net-setup tool?

I just solved my problem. I had eth1394 (firewire) driver at eth0 and my network card driver at eth1. So logically connecting through eth0 did not work.

You can try

Hello!

This isn't a thread Hijack, but a big Thank you out to Tomasm and Zxy. I had the exact same trouble as the OP. I knew it was my firewire on eth0 and didn't have a problem getting the route to stick for eth1 when doing my config from the minimal install CD. However when I rebooted into my newly made kernel I had no network support, and realized my network driver didn't autodetect like it did on the CD. I assumed using genkernel with udev and coldplug it would see it.

Thanks for the tips to troubleshoot the problem.

I'm a complete linux novice after not having worked with any distro in close to 5 years. God how things have changed in that timespan.

ethtool is on the minimal install CD, so I assume it'll be on the other one.
