Can I turn off my ADSL2+ modem when I'm not using it?

[#1]

I like to turn off my ADSL modem at night and when no one is in the house to save energy.  Will this confuse the ADSL2+ connection?  Do I need to leave my ADSL2+ modem on constantly?

Hi there,
You can turn the router off when you are not using it.
The one thing to avoid is turning it on and off repeatedly within a 15 minute period of time.

many thanks for the very quick reply!
