CentOS - Feb 2015 - network automatically connecting on boot after new service installation

2 weeks ago, i had my internet service changed from copper DSL to
fiber DSL.

now, every time i reboot, internet connection is automatically
connecting on boot.

before last update to 6.6, i could configure connection, now i can
not bring up configuration window to disable auto connect.

because of uneasy feelings about leaving computer up when i leave home,
i disconnect 'bell line' so that when i am gone and have a mains failure
and ups shuts down, i will not have internet connected when mains
restore.

also makes for uneasy feeling when retiring for night. :-)


what do i have to do to change this?

any and all replies / suggestions greatly appreciated. tia.

my DSL is delivered as an ethernet connection, there's nothing to 
connect or disconnect, although I suppose I could use ifconfig eth0 up 
and ifconfig eth0 down

If you use Network Manager, just right-click on the little doodad in your panel
bar and un-check "Enable networking".  When you want to re-connect,
right-click on the little doodad and check "Enable networking".

This will work regardless of whether your computer is hooked up with a wireless
or wired ethernet connection.

failed to mention the modem i have is a 2Wire 3800HGV-B.

connections, top down are;

   Auxline - Lines 1&2 - Phone Line - Broadband -
   Local Ether Net 1, 2, 3, 4 - USB-PC - Coaxline - Power

input is via Phone Line, Broadband, or Coaxline. rest are outputs.
except for Power. ;-)

instead of using 'ifconfig', i have a network icon in 'system
tray'.
see my reply to Frank Cox.

well, i guess i have 'Network Manager' if it is the network icon, aka,
"doodad", in the system tray. but it does not give config menu in
center of screen as i used to see.

your reply got my 'chemo brain' to thinking again about what is
presented for right-click.

with right-click, a settings menu pops up with;

  [ ] Enable Networking
  [ ] Enable Wireless
  [ ] Enable Notifications
  (i) Connection Information  {grayed out}
  [ ] Edit Connections
  (i) About

Enable Networking and Enable Wireless must be checked to enable either
when icon is left-clicked and network _will_auto_connect_ after reboot.

if both are unchecked, left-click activates a grayed notice of
'Networking disabled' and network _will_not_auto_connect_ after reboot.

if only it would with out auto connect on reboot.

thanks again for reply. open to more suggestions.
