[FSUG-Bangalore] Download

Hi all i have an internet connection with speed 4Mbps and my plan is offering free unlimited download from 2AM to 8AM but with a monthly limit of 2.5GB. Usually i download more than 50GB a month by not sleeping in the night. But nowdays i feel tired in the night and has to wake up early morning. But this week i have to download a lot especially the distros which may be as large as 4.5GB each.

I wish if there was a solution if my laptop would automatically turn on at 2am and start downloading the stuffs which i have placed in the queue/scheduler of the download manager and stop downloading at 8am and turn off automatically.

Any way to do so? Even partial solution?
