@ArcherC8 When the WiFi is scheduled off, the guest networks are disabled, too.

@ArcherC8 They get the TP-Link Parental Controls captive page (connected to WiFi, no internet access), but when they fire up the VPN, it works anyway.

@Seganku Definitely not ideal, but effective and I figured that would be the best available solution. Rebooting the router doesn't help because they can still initiate a VPN session after Bed Time...

@ArcherC8 I'll give that a try. Too bad the parental controls are so easily bypassed.

@ArcherC8 The guest networks don't seem to have a schedule on this router, but the WiFi radios themselves do.

@Tony Access Control doesn't seem to be scheduled or time-bound and I don't want to be moving them in and out of the blacklist each day. I think WiFi scheduling will suffice for now. Thanks!
