Check your guest settings as many routers have scheduling for the guest network.

@ArcherC8 Thanks for the reply!

 

I have checked throughout the Guest Network settings and have not found anything there either.

 

I'm currently using an outlet timer to power down the router at certain times, but if it is possible I would like to have an option on the router so I can still access my wired PCs if needed without having to bypass the outlet timer.

An inexpensive option would be to get an WIFI extender such as the RE220 set up with a different SSID/Password (not Mesh), and put all of the WIFI devices you want off at night on that SSID. For example, the user guide for the RE220 https://www.tp-link.com/us/user-guides/re200&re220/conventions#ug-sub-title-7 See chapter 7 Set Power Schedule. If you get an extender, review the user guide to ensure it has scheduling for the model you select.

Thanks again, I had not considered this. I already have a range extender that I did not have a need for since we have moved. Checking now to see if it has the needed options.
