Yes, the time of ONT is synchronized (the field “System time” in the screen “Status > Device information” shows the same date and time of my computer).
PROCEDURES:
TEST A – FROM DISABLED WIFI WITH START TIME & END TIME IN THE FUTURE
I disabled the check "Enable WLAN" in the following screens:
• WLAN > 2.4G Basic Network Settings
• WLAN > 5G Basic Network Settings
At 17:30 I set up the screen: "WLAN > Automatic WiFi Shutdown" as follows:
Start -> 17:40 / End -> 17:50 / Days -> All enabled
When time arrived to 17:43: no WiFi switch up.
--------------------
TEST B - FROM ENABLED WIFI WITH START TIME IN THE PAST & END TIME IN THE FUTURE
I enabled the check "Enable WLAN" in the following screens:
• WLAN > 2.4G Basic Network Settings
• WLAN > 5G Basic Network Settings
At 18:00 I set up the screen: "WLAN > Automatic WiFi Shutdown" as follows:
Start -> 17:50 / End -> 18:10 / Days -> All enabled
When time arrived to 18:13 no WiFi shutdown.
------------
Both WiFi are affected (2.4G and 5G).
All tests were controled by checking the state in the following screens
• WLAN > 2.4G Basic Network Settings
• WLAN > 5G Basic Network Settings
And also with the SSID broadcasting and connection in an iPhone 6s and a laptop
I always waited 3 minutes for any automatic change.
If I reboot router via screen “System tools > Reboot”, the checkBoxes of both “Enable WLAN” appears checked (even it was disabled by me).
Thanks so much for your support
