I have been using an airport express for the past two years without a problem. I recently moved and upon moving i bought a new airport extreme for coverage throughout the house. I've heard you can relay the two so i can have my epxress in the living room with the stereo for itunes and the express in the office with the printer all the while extending the wireless connection. Since loading the express software and configuring the router, i cannot set up the express. I've tried direct ethernet connection to the express but my computer still won't identify it. Any ideas as to why this happened or what i can do about it?
