A bit of a faff,
This review is from: ZyXEL WAP3205 v2 300 Mbps Wireless N Access Point (Electronics)
Customer review from the Amazon Vine Programme (What's this?)
I am connected to Virgin Media and as such have an IP address which does not fall into the 'acceptable' band detailed by Zyxel. As I didn't want to mess about with my settings and risk knocking my internet off completely, I decided to connect using a Powerline adaptor which is not ideal as it cuts speeds. I eventually just relocated my current modem and found that that simple measure has extended its range without the need to use an extender or access point.
If you are on an ordinary network provider then this will probably work better for you than for me. It is a nice design and provides a number of setup options for you dependant on your needs but just wasn't best suited to mine.
