    Here is what I would like.
    I want to connect a new D-Link N Router (I'll call it router B) to a older router (Call it router A).

    My setup.
    Our internet line comes in and goes to router A which is broadcasting unsecured. (I know it's not safe, but we run a campground and the owners want is free and unsecured.):mad: I then want to run a LAN cable from Router A to Router B. Router B will be broadcasting secured.

    My question is, even though Router B is secured, would it become vulnerable or unsecured because it is running through a unsecured router (Router A)?

    Thanks for the help!

    On Router A, there should be options about letting the wireless clients associate with other things. So you should be able to allow the wireless people on router a only have a connection to the internet

    Depending on what Router A is, have you looked into DD-WRT? it is a Linux firmware that runs on many popular routers. It has a lot more options than your manufacturer's firmware has.

    Link: DD-WRT

    It all depends on how you setup router B. As long as router B is setup secured (not just wirelessly but also with port forwarding, etc.) you shouldn't have any issues. As far as security goes it is just like plugging router B straight to the internet without router A (although I'm sure you have a firewall enabled even though your wireless is unsecured) so as long as B is secure you are good to go.

    Not 100%. If your goal is to prevent users on router A direct access to the computers on router B, that would work. However... If an user on router A can act as a man in the middle, it can capture all your data coming out of router B. The easiest thing to do, is to buy a third non-wireless router, lets call it C. So what you will have is Router C connected to your broadband, and router A and router B connected to router C.

    A couple of configuration notes: use different subnet ranges for each of the routers. So Router C will be 192.168.1.x, Router A will be 192.168.2.x, Router B will be 192.168.3.x.

    Hey thank you all for the info and help! I mainly wanted a secure network so that could share files and a printer without the rest of the world accessing it. I I got my setup running though but another question.

    Am I going to notice any major slow down in my internet speed due to all of the information on router B going through a LAN cable?

    Thanks again!

    Thanks you all for the help. Another problem has risen though.

    I networked a printer to the secure Router B, however it is showing up on both networks. (Router A and router B's networks.)

    Is there anyway to make the printer only show on Router B?

    Thanks in advance.
