What firmware is best for me ?

What firmware would be best for me?

I want to be able to schedule by mac address when a device is able to access the internet

For example block a device every day between 3-5pm

In the stock firmware it doesn't really let you do that by mac address. I have kids and comcast limits me 1TB per month and if I let the internet open 24/7 all my limit is gone half way through the month

I want to be able to have a list of devices that can only access on certain hours and perhaps measure bandwith as well
