Can The Airport Express….


I currently use an old Linksys WRT54G v6 wireless router. I have tried to set it up to deny certain devices from connecting to the internet at certain times and days of the week using their MAC addresses. It worked for a while but sometimes instead of denying a device between the times of 12 am - 6am on weekdays it denies the device all the time including weekends. It was set up to be enabled for some of the device(s) to connected to the internet on weekends. So my question is, can the Airport Express (June 2012) be set up to deny/enable devices to connect/disconnect from using the internet reliably?
