I am using static IP address of 10.1.0.8

+ I see on my switch no "live" network connection - so it
  appears that the NIC is not active.
+ 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

I am able to ping localhost or the hostname (resovled via /etc/hosts)
itself.  Just cannot ping remote sites.

>ftp.microsoft.com' and ftp returned the error 'Blah blah blah.)

+ ping 10.1.0.11
PING 10.1.0.11 (10.1.0.11) 56(84) bytes of data.

/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

Additionally, I checked:
+ lsmod | grep atl2
  alt2   32024 0
+ cat /etc/modprobe.conf
  alias eth0 atl2

Thanks-
