Hi I am trying to set up my TD-W9970 router so it blocks a smartphone and tablet after 12am until 8am. The only problem is apparently the parental control is whitelist only which means internet access is continuesly blocked no matter when. I don't want any site restrictions when the internet is available. Is there a wildcard that allows all sites to be used or any work arounds? Between this issue and only have four MAC addresses available to block, I have to say it is a pretty terrible parental control system compared to all my previous routers.
