I have an Airport Extreme Base Station and a Airport Express sitting in boxes, never being used. Our house is already equipped with wireless connection through our DSL and Linksys router. (was in place when I moved in) I was thinking of getting a time capsule for back up, but not sure if I could get it up and running with the Linksys or not. Can I use my Express as an extender for using my laptop in the backyard? will it talk nicely with the Linksys? What are your suggestions/opinions? I hate to see my beautiful Apple products sitting in boxes. ??
