Wireless router with guest network scheduling

[huffiewuffie]

Hi, currently I'm using Dlink DIR-868L that has a feature to switch on/off for guest wifi (leaving the main wifi untouched). Did a search and noticed (from setup screenshot) only a handful of older TP-Link routers has similar feature whereas the rest of the routers will affect the main wifi as well. As such, would like to know if there are any "newer" routers by other brands is able to do it? Or is it possible to do it via dd-WRT / RouterOS (using cronjob to enable /disable) ? Thanks
