Networking :: Non-wireless networking problem
My networking (wired) is not working at all. I have given the same network setup as I have in Ubuntu:
IP address: 192.168.1.8
Subnet mask: 255.255.255.0
Gateway: 192.168.1.1
Broadcast: 195.168.1.255
Name server: 192.168.1.1
I can ping the local host but no other machines on the network.
DCHP does not work even though my router has DCHP enabled.
Does anyone have an idea what is wrong or can suggest further diagnostics.

Maybe your network card isn't supported; pinging localhost doesn't need a net card anyway.
Try "ifconfig -a"; does it list eth0?
What is the error when you try to ping something?
I pinged local host just to prove that tcp was up and running. Here is the full listing from ifconfig
eth0 Link encap:Ethernet HWaddr 00:16:EC:7F:59:CF

resolv.conf has the following line in it:
nameserver 192.168.1.1
By the way I am using DSL 4.3.4. The network card is reported by Ubuntu as Realtek RTL-8139/8139C/8139C+
Tony
Oh, and pinging the other host gives 'host unreachable' of course
I use rtl8139 without issues.
Perhaps an irq issue?
Check with dmesg | grep -i irq
or
cat /proc/interrupts
