Need to completly block netflix in my router. Room mate is constantly streaming even when he is not home and its using up too much data. I did block netflix, netflix.com ect. Problem is that is uses it on his tablet, he will start streaming on his data plan then switch to wifi and it will continue to stream on wifi. Is there a way to block it all together? I have a BUFFALO AirStation WZR-600DHP router, so i know there are tons of settings. Anyone have any suggestions?
