InternetOff

PROS:
This is not a filtering program. Which suites me completely
Very simple UI
Left click Sys.Tray icon to toggle connected/disconnected
Turns Internet connection (Wifi and LAN) ON or OFF via System.tray icon
Manual on/off is a toggle on the InternetOff menu popup

The only settings are scheduling on or off
Quick temp Internet disconnected via Sys.Tray menu-popup
Settings: one dialog, three tabs, General (3 choices), Password (optional), Schedule (optional) ... in one hour blocks

CONS:
No short cut keys
"Turn off the internet" on the popup then shows a range of times to be off

• there is no way to simply toggle OFF, there is no default setting
• to "turn off" requires extra mouse clicks
  ON is very simple single click

Very slow to respond to ON/OFF, I am Running VooDooShield (and Free Bitdefender) ... VDS waits for "InternetOff" to finally kick in
Icon appearance can be sabotaged, easily reset with "IOffSvc.exe" in root folder ( a shortcut on Start Menu to fix)

All in all I am very pleased with "InternetOff" it is the ONLY simple toggle of Internet connection I can find.
Beats yanking the LAN cable out
And its free
Developer "CrystalRich" have a v.good reputation (IMHO)
