On-board NIC

["Brent W." <brenthel yahoo com>]

I have my eth0 up and running(ifconfig).  set-up ip
address with netconfig.  when i ping anything but lo
interface(which by the way means nothing) i get
Destination host unreachable.  my router led is not
showing a connection.  

dmesg | grep eth0
eth0:RealTek RTL8139 Fast Ethernet at 0xc284a400,
00:90:47:00:b5:cv IRQ 15
eth0:identified RTL8139 chip type 'RTL-8139c'
eth0: setting 100mbs full-duplexbased on
auto-negotiated partner ability 41e1




My puter is old. I don't even know what type of card
it is or if it is supported.  Therefore i plugged in a
3com 3c509b card.  Now lo, eth0, and eth1 all up on
ifconfig. Same issues, however the router led flickers
with no apparent pattern.

i have a hardware address and IRQ number.  does anyone
have any suggestions for a newbie?

thanks
