I purchased ZyXEL WAP3205 v2 because I have a new house that is over 3000 Sq. Ft, so I want this to be a repeater. I am having a difficulty setting it up. One of the things it says is that I need to change my IP address. The instruction for change says to changes the IP address manually but it says to put your Subnet Mask and Default Gateway. How do I find out what to put as the Subnet Mask and Default Gateway? I am using Windows 7 64 bit.
