|I'm just wondering..How secure is this? I basically want anyone connecting from the wireless to be limited to just connecting to the internet, not connecting and seeing any other computers on the network.|
Assuming your subnet mask is 255.255.255.0 in both cases then your two subnets are indeed separate. As to whether or not computers connected to the wireless can see the wired subnet it's hard to say without examing the routing table of your wireless router.
A quick way to check is try to ping a couple of devices connected to the other subnet. To do so, all you'll need to know is their IP addresses. Go to at least two computers on your wired subnet and open a command prompt window (ie: Start >> Run >> type cmd and hit Enter) and perform the following command:
Make not of their IP addresses and then go to a wireless client, open a command prompt window and try to ping both of the addresses you made note of from the other subnet.
If you get no replies, then chances are the only thing they'll be able to see is LAN side of the actiontec router (try pinging it's LAN IP) and they won't be able to get into the wired.
If however your wireless clients are seeing the wired, reverse the routers. With the wireless router connected to the internet and the wired router daisychained to it, the wireless clients will not be able to see the wired.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
