I just received airport express and live in the basement. I have wifi in my suite but don't have a hard connection to connect wifi to it. I want to use it with my iphone and MacBook and samasung galaxy but can't because she. I connect to the network I have set up with the airport express it takes me off the network I normally use to connect to the Internet. How can I do both. Use the wifi Internet from upstairs and still use the airplay features of the airport express? am I not explaining myself here, I could really use some help!
