It seems you have to set the Time and Date manually. Once this is set it helps with many other problems with the router. But does not seem to fix all of them. One thing I did not check is if the Time/Date is getting reset to 2011 on every reboot.
Forgot to mention about making sure Date and Time are set correctly before you do anything else with the settings
There is a problem with Time and Date; On factory reset it gets set to the year 2011 and some strange date; The NTP time server function does not seem to be working or has to be set to something other than DLink time servers
