We'd like to add a secondary router after the virgin box. This is so we can add proper parental control for broadband access. We have tried using the Virgin router software but it doesn't work. Can we do this, we are looking at Netgear? Any ideas?
Yes you can. You will just need to put your hub into modem mode and let the new cable router handle all the routing and wireless functions. A decent third party router will give you many more features than the firmware crippled hub, and probably better wireless performance. The Netgears do seem to have decent parental control.
Some internet security software also has parental controls like Norton Premium.It is always wise to run a firewall\antivirus software on your computers.
There are instructions on how to put the hub into modem mode here
You will need to set up the new router first.
You will need to connect the router to a PC and access it's GUI and check that the WAN settings are set to Dynamic IP or DHCP depending on which router you get. It should come with full instructions on how to do this.
Once set up you will then need to do a power recycle.
Turn off the Hub and connect the router using the port next to the coax cable and the WAN port of the router. (It will be marked WAN) Note do not power up the router yet or connect any devices to it.
Power on the hub and wait a few minutes until it connects to the internet.
Power on the router and wait for the lights to settle down once it has obtained an IP address and connected to the internet and you should be good to go.
No extra router needed .. Have you tried 'wifi blocker' app on Apple Store. It works great with the hub3. We use it in our house .. you can hear it works with out 13yr old screams when she's blocked lol.
