From the main web menu Dashboard, go to the Advanced tab, select the System Tools then click on the Time settings tab to adjust the System tab of your device.
TP-Link routers feature a built-in web-based management utility. This internal web server does not require the router to have internet access. It does however require your device to be connected to the TP-Link router’s network. This connection can either be wired or wireless and can be accessed via any device with a web browser like a desktop computer, a phone, tablet, iPad, etc.
