Turn Off Or Leave On?

Hi, I'm migrating today from talkshite to ukfsn and hopefully a much faster connection!

Do I need to turn my router off overnight to facilitate the changeover of isp's or can I just leave it on and when it doesn't connect tomorrow (after the change) just input my new details and take it from there?

Cheers
Rick

You can just leave it on, then change your details to see if you can connect.

Thanks mate.
