I have an airport extreme, previously installed and working fine for my wireless connectivity. I wish to extend the coverage range for my new home.

I learned that air port express can extend the coverage. I bought 2 airport express and manage to configure 1 unit to extend the range. I am thinking of configuring the 2nd Airport Express to extend the range from the 1st Airport Express like the diagram below;

VDSL---AExtreme ))) AExpress )))) AExpress

Will it work? How can I configure it. Can someone advise me? Appreciate it. Thank you.
