Failed to start if no Internet connection is available

[Demian]

I like to start the script with the gnome session, but if there is not yet an Internet connection this will fail.

So the script should stay running and wait for connection.

i support this answer by having the same issue.
i'm a notebook user and always manually create an internet connection (HSDPA) when my session is alive again (except when i'm using wlan or lan)

The same goes for me!

It would be nice to have either a small delay at start-up, since in my case it takes a while for establishing a connection, or an option, that this script searches from time to time for a connection, when it failed to connect at start-up.
