I have a couple of questions so hope its easier to have them both in the same thread.

1) I have a 2925 downstairs and a 2930n in the attic set up as a repeater. My issue is that it works for a while (My phone finds it no problem and shows excellent connection) then just stops working - anything that tries to connect only gets a very poor signal from the 2925. I have to turn it off then on again and it works again, for a while. I have them both on the same SSID - would it help (and is it possible) to give the 2930n repeater a different SSID?

2) very different issue here. I am struggling to set up access restrictions to wifi on the 2925. What I want to do is stop the kids being able to access wifi after 9pm. Rather than the confrontation of taking things off them if I stop the internet and claim ignorance then war is averted

I have set up the schedule but can't seem to isolate the MAC address of the phones and link them to the schedule. At the moment wifi just goes off at 9 for all of us (Arguably no bad thing) but I'm not entirely sure what I'm doing wrong.

Any help with either issue would be greatly appreciated.
