Timing Control. Enter the time of the day you would like your policy to apply. The Router is not designed to have
a built-in battery mechanism for a real time clock, so shutting down or rebooting the Router will cause the Router
clock to be out-of-date. The Router will automatically check the NTP and correct the time when its internet
connection resumes. In case that the NTP is unreachable, you will have to reconfigure the Router clock to ensure
that all these time-specific functions will work properly. Because of the interval of the page refresh timing, the
clock may have a maximum of two minutes variance.
If you have enabled the Timing Control on Internet Access function and leave the Router unused (power-off or not
connected to internet) for a long period of time, you will have to check the Router clock and ensure it has the right
time by the time you start to use the Router again. If the Router fails to connect to the NTP servers and can't get
the time updated, you may need to change to different NTP servers. You have to make sure of the right Router
time setting to ensure that Timing Control function works correctly.
Blocked Services. You may choose to block access to certain services. Click Add/Edit Services to modify these
settings.
Website Blocking by URL. You can block access to certain websites by entering their URL.
Website Blocking by Keyword. You can block access to certain website by the keywords contained in their

Default Access Rule. This is the global control of the Router's default access rule. It has allow or deny options. If
you select allow as the default action, the Router will allow all types of applications at any time to access the
Internet. Also you can set up to 10 access control policies to deny the PC or certain types of Internet services in a
certain time to access the Internet. Aalso known as the Black List.)
If Deny has been selected as a default rule, the Router by default will deny all types of access at any time to
access the internet. Also, you can set up to 10 access control policies to allow the PCs or certain types of Internet
services in a certain time to access the Internet. (Also known as the White List.)
