If you're connecting multiple Airport Expresses by ethernet cable to the base station, do you have to have an Extreme operating as the base station to create a single, large network? Or can you connect two AE's to a random brand of modem by ethernet cable and match all their network settings to each other to create a single, larger wifi network?
I should clarify that I know you can't extend the Wifi network of a non-Apple brand router. What I'm asking is, if I disable the wifi aspect of my current modem/router, can I connect two airport expresses to it via ethernet, and have them create a single wifi network?
I don't really want to spend the money on the Extreme (which I don't really need) to go in the lounge room, when I'd rather the audio output from the Express to be available at that point instead.
