Hello, per you know, the Archer C9 V5 does not support wireless schedule yet, while we have noted that and reminded our R&D colleagues. 

For now, if you want to turn on/off the wireless function regularly, you can turn it on and off as a workaround; 

Or if you want  to block some devices access internet by disable wifi feature, you can use the parental control to achieve it. 

For the new feature added, you can keep an eye on official website-firmware release note. Any updates, we will post there.

May it help and have a good day.
