My questiion is that how do you find the primary dns and second dns?
The reason why is that I'm trying to set up my console wireless

You don't generally have to know it explicitly. DHCP will return the correct values.

Setting the DNS address to your router address should work fine and it's simple.

There are other ways of finding the explicit address, though.

One way to find out what DNS server your ISP will allow you to use is to connect your PC directly to your Cable/DSL modem. Then once connected to the Internet, go to a command prompt and type IPCONFIG /ALL. The information will show you what the Primary and Secondary DNS servers have been alloted to you by your ISP's DHCP Server.
