I have D-Link ADSL router (DSL-502T).From next month ,I will have unlimited Download during night i.e between 12:00 am to 8:00am .According to my ISP, I should switch On the modem or router after 12:00 am and Switch it if off before 8:00am ,so as to enjoy unlimited download during that period .So I want to know a way to automatically disconnect the CPE or Router before 8:00.So that I will not have to worry(I don't want my sleep to be disturbed ) about swtiching the CPE off automatically before 8:00 myself during holidays in June .
