I replaced my Linksys WAG160N as it was getting unreliable and kept dropping DSL (requiring reboot - a known feature of this product) The TP-Link 8960N seems to perform great BUT the access rules and parental controls don't seem as flexible as those on the old Linksys.

Problem:
I previously used to be able to block internet access based on keyword which was real useful, eg youtube, vimeo, mtv - to slowdown the teenage broadband plan consumption rate (usually in the back end of the month). Advantage on keyword blocking was if the word appears anywhere in the url it is stopped. 

Question:
Is there anyway I can restore this kind of functionality, or am I missing something in the TP8960N setup that could replicate.  I did have a brainwave and reinstated the 160N as a bridged router, BUT in this mode it seems to ignore any of the Access / Parental rules, it is in DHCP disabled mode. 

Any clues?
