While configuring the Wireless feature in the Tp-link extender through the tplinktrepeater.net interface, you can set up the schedule according to which you want to turn on and turn off the Wi-fi connection over the extended network. If you want to apply the schedule for every day then select the “Always” option and if you want to apply the schedule for certain days, select the “Selected day” option. After adding the schedule, make sure you select the “Wireless Off Time Schedule” function to trigger the Wireless schedule feature.
