500C+ Reboot my modem before starting night download ?

i have 500c+ plan which have the night unlimited facility,,,,do i have to reboot my modem before 2 am if i want to start a heavy download session?? or i just have to reconnect the internet,,if any body can give me a helpful answer i will be thankful,,

I had this plan for a long time, you don't have reboot, once its 2 am, bsnl automatically reset connection and your unlimited download starts working. Still if you are unsure then simply reconnect after 2:00 am .
