How to put a total ban on a device on a network?

Hi. How do I put a total ban on a device? I've tried changing passwords, but I get complaints whenever I do this action. So I need to completely ban access? It is online right now. This device has consumed 6GB of data in 24 hours.

I have enabled "access control" on the device, but it's not 24-7; for example, between the hours of 9:30pm to 6:30pm. Which figures do I input for this complete ban? But, I need to completely ban it so I can prevent it from consuming anymore bandwidth.

Is this connecting thro' a router? If so, which router?

Some routers if you want to block a period spanning midnight, like 9:30 PM to 6:30 AM (I think you meant), you would need 2 schedules, like 9:30 PM to 11:59 PM & 12:00 AM to 6:30 AM.

So to block all day you'd just use the schedule 12:00 AM to 11:59 PM. If you're using the 24-hour clock, as I expect most routers to, you'd use the 24-hour times (which are easier to understand in this context)..

Hey, that's brilliant. I do not have a 24 hour feature, unfortunately. So, I've done it like this: schedule line 1  >> 9:30pm to 6:30am. And schedule line 2 >> 6:30am to 9:30pm. Will there be any conflicts?

Why bother with 2 schedules? Just 1 would do : 12:00 AM to 11:59 PM.
