I currently use a Time Capsule for my home Wi-Fi system. I just ordered an an Airport Express which is scheduled to arrive tomorrow. The reason for ordering the Airport Express is so that I can print from my iPad to an Airplay printer when I organize a fundraiser next week in a location that does not have Wi-Fi (nor cell service). The Airport Express will not be connected to the net, just used as a Wi-Fi hub. Afterwards I was planning on using the Airport Express as a repeater/relay to the Time Capsule in my house. I know that I can set up the Airport Express as a new network. However, if I set up the Airport Express to join my existing network and then remove the Airport Express from the network will it work as a Wi-Fi hub without finding my Time Capsule? I know that I can experiment once the unit arrives but I thought I would ask the question here in case anyone has experience with this question.
