I want to lock my kids out from the router at night, Is it possible to set devices to only be able to access the router at certain times? I don't want to turn the modem off every night, I just want to be able to lockout specific devices. Is that possible?
Yes. On your Admin page, there should be a Wireless Tab and a Parental Control section.
The Router's Admin page, or my Cox Account Admin Page. My Cox Account admin page does not allow me to configure access. I have been told by multiple Cox techs that their modems are not enabled to configure access by time. That answer seems a little lazy, but it may be accurate.
Your router. I wouldn't think Cox offered a router without Parental Controls.
