I don't know *how* to tell if I'm running network-manager, but,
I'm running whatever everyone else runs on Centos since the
home broadband network has been working for a year or more with
this laptop without problems.
When I set the laptop back to normal (on the home wireless network),
here is what shows up when I right click on the network icon:

Interestingly, that ifcfg-eth0 file doesn't exist in:
$ ls /etc/sysconfig/network-scripts/ifcfg-eth0
=> ifcfg-Auto_eth0 ifdown-post ifup-ippp ifup-tunnel
=> ifcfg-lo ifdown-ppp ifup-ipv6 ifup-wireless
=> ifcfg-wlan0 ifdown-routes ifup-isdn init.ipv6-global
=> ifdown ifdown-sit ifup-plip net.hotplug
=> ifdown-bnep ifdown-tunnel ifup-plusb network-functions
=> ifdown-eth ifup ifup-post network-functions-ipv6
=> ifdown-ippp ifup-aliases ifup-ppp
=> ifdown-ipv6 ifup-bnep ifup-routes
=> ifdown-isdn ifup-eth ifup-sit
But, that file does apparently exist elsewhere:
$ sudo updatedb; locate ifcfg-eth0
=> /etc/sysconfig/networking/devices/ifcfg-eth0
=> /etc/sysconfig/networking/profiles/default/ifcfg-eth0
$ cat /etc/sysconfig/networking/devices/ifcfg-eth0
=> DEVICE="eth0"
=> NM_CONTROLLED="yes"
=> ONBOOT=yes
=> TYPE=Ethernet
=> BOOTPROTO=none
=> DEFROUTE=yes
=> IPV4_FAILURE_FATAL=no
=> IPV6INIT=no
=> NAME="System eth0"
=> UUID=5fb06ba0-0bb0-7ffb-45a1-d6edd65f3e03
=> HWADDR=A0:BE:C1:D8:E5:F1
=> IPADDR=192.168.1.254
=> PREFIX=24
=> GATEWAY=192.168.1.20
=> LAST_CONNECT=1346858976
Q: Does the information above help?
