Adding a real router to a modem with built-in wireless.

Hey there. For the longest time, I've been getting internet from a SMC8014WN Wireless Cable Modem gateway and I've been having sporadic connection issues ever since. I use Wireless USB Adapters on my own computer to connect to it from across a hallway and into another room and the connectivity is not very consistent.

No matter what adapter I use (I have many) I sometimes get "now connected" messages and when I'm playing games like TF2 my connection either spikes, or drops and comes back (I'll get DC warnings and the game will freeze, and then come back in) so I'm thinking my connection is pretty crap.

I'm going to be getting a new computer (this one is 5+ years old >.>) and I want to make sure I have a good connection. I'm thinking about getting something like this:

I'm asking if I could connect a router like the RT-N66U to the modem in the other room. Is this possible/advisable? Thanks.

  1. You can always daisy chain routers, WAN to LAN. You just have to make sure each uses a different network. So if the SMC8014WN is using 192.168.1.x, perhaps make the RT-N66U 192.168.2.x.

    [smc8014wn (192.168.1.x)](lan)<-- wire -->(wan)[rtn66u (192.168.2.x)]

    But you now have two firewalls and are double NAT’d. That complicates port forwarding. So I suggest giving the RT-N66U’s WAN a static IP from the network of the SMC8014WN, then place that IP in the DMZ of the SMC8014WN. That effectively eliminates the outermost firewall.

    Finally, you’ll want to disable the wireless radio of the SMC8014WN, and not use any of its remaining LAN ports.
