s it possible to set my wifi router(DLINK DIR 615) to reboot automatically at certain times(etc. every 4 hour once?)

and is it possible for me to restrict torrenting and PPStream?its unfair for other users,u now. hope u guys can help me with it?

for the time i'm using d-link (dir 615) customised with dd-wrt firmware.

if its possible increase the total users number at one time(curently is 45,i presume) and limit the bandwidth to each users?

thanks and festive greetings
