I must have installed something that now prevented my

I had a hard time initially to compile/build the module for
my onboard network but I did have it running and it was
really great.
But somehow, I have lost it.
Can someone give me advice how to go about troubleshooting it?
What I do know is that the network daemon is running, it correctly
loaded the nic module, ipconfig shows both eth0 and lo:
ifconfig:

I checked /etc/resolve.conf, system-config-network and everything
is in order.
What makes you think that you have lost your network? ifconfig shows
that networking is running and has an IP address (10.1.0.8).
We'll need some additional information:
* How do you have your network configured? Are you using a static IP
address or DHCP to assign and address?
I am using static IP address of 10.1.0.8
* What gave you the impression the networking is not working?
+ I see on my switch no "live" network connection - so it
appears that the NIC is not active.
Well, if the link light isn't lit that is the first problem that needs
solving. Without it, nothing else will work.
+ I cannot ping a local server
+ I cannot access an Internet site like www.fedora.org
+ gkrellm shows no activity
+ nslookup finds no DNS server
Expected.
I am able to ping localhost or the hostname (resovled via /etc/hosts)
itself. Just cannot ping remote sites.
Also expected. Pinging the localhost or hostname doesn't involve any
hardware. So, still need to resolve the link light not being on.
/sbin/route:
================================================================
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.1.0.0 * 255.255.255.0 U 0 0 0 eth0
link-local * 255.255.0.0 U 0 0 0 eth0
default 10.1.0.200 0.0.0.0 UG 0 0 0 eth0
================================================================
It doesn't make any difference, but it would be nice to see the output of
"route -n".
Additionally, I checked:
+ lsmod | grep atl2
alt2 32024 0
+ cat /etc/modprobe.conf
alias eth0 atl2
What kind of hardware is your NIC?
Have you tried the following?
1. Stop your network (service network stop)
2. rmmod alt2
3. modprobe atl2
4. Start your network
5. Check /var/log/messages for any errors
