That is, you can customize when you connect to the Internet.
For example, your broadband fee is a time limit, assuming 600 hours per month, timeout charges, then you can set a timed connection, according to 31 days per month, the daily online duration can not exceed 19 hours and 20 minutes, so you can set the router 4:40 connection every day, 00:00 disconnect, neither affects the normal Internet access, and will not timeout.
It is even more important for users who are billed by hours and hours.
For example, if you need to control the Internet time of your children at home, you can set it to go online at 8:00 AM and disconnect at 10:00 PM every day.
