Wonder if anyone can help with this one.

I've successfully extracted and setup my Belking Playmax router on Sky, which works fine. The problem starts however when i turn on access control (as i limit my daughters time on the internet) and add a computer, it starts to block some websites even though the only restriction on it is time and this hasn't kicked in yet. I had this setup previously with 02 and it worked a charm. I've not changed anything other than the settings to connect to sky.

Anyone got any thoughts?
