I can't turn off and turn on the wifi in certain hourly sections. I installed wifi schedule, programmed it correctly but it doesn't run.
Runs fine for me ;- )
Debug it, how have you programmed it?
What version of OpenWrt are you using? I think anything before 19.07.3 contains a bug that doesn't properly enter the scheduled task.
Here's the fix if you need it.
OpenWrt 18.06.1 r7258-5eb055306f / LuCI openwrt-18.06 branch (git-18.196.56128-9112198) So that's the problem
Untick it so it is disabled, leave it there, save&apply. Check "View cron jobs". It should be filled with entries. There was a bug that it only runs when disabled.
Verify the checkbox "Force wifi deactivation even with associated stations" is flagged on 2.4 e 5GHz. Otherwise it remains active as long as you have some device connected.
