Many ISPs (Internet Service Providers) cut your Internet connection whn they detect that your PC has lost the signal during a certain amount of time.
You are then obliged to reconnect your PC to the Internet again with all the hassle this brings, but it won´t happen with Rasputin 2.0.

It is a simple to use program and works in the background, consumes few resources and doesn´t even need configuring.
