Airport Express as second router and airplay device
I have a D-Link DIR655 as my primary router / wifi network and an old airport express which is used only as a client to stream music to the home stereo. Wifi is not turned on on the APExpress.
The D-Link is connected to the APExpress via ethernet since wifi drops off across the house.
Although it works fine for this limited use, I was considering upgrading the AP Express to a new one, mainly to solve the outdated utility problem. In addition to acting as a client for iTunes, I would like to configure this router to have it's own wifi network for internet access in that part of the house, either as an extender for the first router or a second wifi network. (If dual networks, I can already see a possible issue with airplay if the source computer is on the d-link network).
How would you all set this up?
