I have my parental control setup to block access from 22:00 to 09:00 however, it does not automatically allow access when the time changes to "unblocked" time. Oddly, it still displays the "parental control block" message. I am forced to disable parental control to allow access to the devices after 09:00 and then need to re-enable it at 22:00 to block access again.
I have also updated to the latest firmware (1.1.42.161129). There does appear to be 2 versions (V1.0 or V1.1), however, these both appear to be the same file. I have used the correct version for my router (V1.0).
