I'm trying to setup the access restrictions by MAC address so I can block specific web sites and such for my younger siblings computers but as soon as I enter the MAC address of their computers and save the configuration my computer doesnt get internet. I had this working fine where I'd have full capabilities of the internet and they be restricted through the router but ever since I updated the firmware about all I can do is just put their computer IP or MAC in the restricted access and disable the internet for them or put my computer in the access restrictions and restrict the web sites that my parents don't want them going to like youtube/myspace so I'd be blocked from those too. What would be the problem of me not being able to get internet if I just put their MAC or IP addresses in the restricted access and blocked web sites or key words that way? Any help be appreciated.
