So disabling NTP server makes Access control work? 
I have the same issue.
Region: NA
HW: A1
FW: 1.04
If I use ntp server to set the router time, Access Control gets messed up. This afternoon was the worst - I checked the time on the router (which I have to do every few days as it slips out of sync very quickly, or even resets itself to something random - one morning last month, it was set to December 31st, 1969!) and seeing that it was out by an hour (no, the daylight saving thing really doesn't work either) I synchronised it with the ntp server.
About 2 minutes later, one of my children appeared, complaining that he had suddenly been blocked from all internet access. His access had been restricted according to the access control rule I have for his devices during 'homework time', still an hour away.
Here's the kicker - it's Spring Break, the rule is turned off....
So, I have learned that if I want access control to work properly, I have to sync the router's time to my computer (and don't ever use the daylight savings option). Then I have to check it regularly for slippage and reset it.
I also have to hope that the router doesn't randomly turn on or off the rules I have set up (if it does, resetting the time seems to work)
Oh, and please don't get me started on the UI, which is the worst I've ever seen on a DLink router - about half the page requests are either unfulfilled or painfully slow. I find IE works a little better than Chrome, but it's not like I use the interface every day, so I live with it.
Anyway, if anyone has an idea how to make the time and access control settings work as they are supposed to, I'd love to hear them...
