We have kids in the house and I'd like to limit their internet access to certain times of the day but because of the great amount of devices they use (phones, tablets, laptops, etc.) the only way I could think of doing that easily was to set up two wireless networks: one that the adults could use 24/7 and the other that the kids could access during certain set hours.

I've tried to do this with limited success. I'd appreciate some help.

Here's the equipment I'm working with:

DLink DIR 615 wireless router
DLink DIR 515 wireless router
Motorola Surfboard cable modem S85101U

I plugged the DLink 615 in, set it up for DHCP client and plugged it into the cable modem. I lef the default 192.168.0.1 IP address for the device. On that router, I also reserved the 192.168.0.199 IP address and assigned it to the DLink 515.

I also gave the DLink 515 device the IP 192.168.1.1 so I could administer it.

I set the DLink 515 to static IP and made the IP 192.168.0.199 and the default gateway 192.168.0.1.

I plugged the DLink 515 into one of the LAN ports in the DLink 615.

I set a schedule on the DLink 615 to shut down internet access to the DLink 515 at a certain hour and turn it back on at another time.

Everything seems to work ok, but at least once a day we have to unplug and plug the routers to reset them.

I don't know if it's a Comcast thing, if it's my setup, but the constant plugging and unplugging is eventually going to mess up the routers.

Can someone please advise?

I have a feeling it has to do with the time schedule and the shutting down of the secondary network and by the way unless you change the password on the personal router they will be able to access it. just by getting the info on the modem.. you would be surprised how easy it is to crack some ones wifi password.

I'm afraid I can't blame the scheduling since the problem persisted when I lifted the schedule while the kids were on spring break. The kids have their own password and on the adult router I change the password every couple of weeks -- I remember what it was to be that young and I try to head off their sneaky teenager ways. :no:

DHCP range on the DLink 615 is 192.168.0.100 to 192.168.0.199
DHCP range on the DLink 515 is 192.168.1.100 to 192.168.1.199

Please explain "easier, if you use the 10.xx net".
I only know enough about this stuff to be a little useful and a little dangerous.
 

Here we go: http://en.wikipedia.org/wiki/Private_network
But as far as i can see, that's not the problem. Can you figure out, if both routers stop working or if it's only one? And do they stop working entirely or only the network connection?

It's the network connection, I believe but I do have trouble logging into the router over wireless when we have these problems. I sometimes have to go plug in a hard wire to access the router.

I don't know if it's related but I've received two advisory emails from Comcast asking me to check my computers to make sure they aren't infected with a bot. I've done that and we're clean. But I'm wondering if it has something to do with the router set up.

Which of the two routers (as I've described) should I set up as 10.0.x.x ? The kids' or the grownups' routers?
 
It doesn't matter, where you use the 10.0.x.x. It only helps you to identify the net you are logged in. What worries me a bit, are the emails frrm your service provider. That sounds like they are detecting suspicious activities on your connection. Maybe you can get more detailed info from the service desk? They may drop the line or block your ip address because of that.
