[lug] Cisco 678 router/modem

[Hugh Brown]

First thing to check is if the appropriate kernel support is there.  

cat /proc/interrupts

should have a line with eth0 in it

I guess if ifconfig reports it then it should be loaded.

The next thing to look at is the device set up in
/etc/sysconfig/network-scripts/ifcfg-eth0

Is it supposed to be doing DHCP from the Cisco?  Your config file should
reflect that.

also look in /var/log/messages to see if there are any comments from the
kernel about eth0.

FWIW,

Hugh
