I just started to use the DIR-850L yesterday and I tested the scheduling feature around 5PM.
The setup is like below: 1) Enable both 2.4 & 5G WiFi with different SSID (say SSID A & B); 2) For SSID A, I associated it with a schedule from 0900 to 2100, and SSID B is always on.
Both radios ran pretty okay until 9PM. When SSID A turned off/disappeared by then, guess what - SSID B was gone as well. I thought the schedule should be able to work independently with different SSIDs, or am I wrong? Have anyone encountered the similar issue?
