I'm trying to use a simple TIME BASE ACCESS, i go to WLAN configuration/Auto Shutdown, and the make my configuration the WLAN is still on even at my schedule.
I've got NTP sincronized.
If they come in only on a specific day of the week from 1:00 PM to 2:00 PM to take inventory and don't need the WLAN to be up for the rest of the week, then yes all you need is one line for that specific day and the rest of the week the wlan will be off.
