Blocking websites is easy to do with this router using the Access controls and schedules. However, I have not been able to successfully block ANY game. This includes WoW, Perfect world, Atlantis, ect ect. The reason I think is that the blocking is using not the IP addresses, but the Domain names. Same with unblocking certain Websites during an otherwise block all. None of them would work until I actually used a Domain Name instead of an IP address. Not really sure why it is doing that, But I have tried ALL options in the router without any real or working solutions. the ONLY way to stop him from getting on the net and playing the game is to completely block ALL internet from that computer. However, interestingly enough, that may not always work as well. I have a laptop on wireless. I can plug that into a cable from another computer and use the net all I want. The problem there is for some reason the router will not actually change the MAC address. So it is using the MAC from the other computer as far as the router is concerned, which is allowed, even though it shows the computer name of the laptop. That would not normally be something tested at D-link or even thought about I think. But the problem IS there. So really, the access controls are completely useless except to turn the net completely off from a computer using a schedule. Only thing that does seem to work.
