Hi, I have a (probably really stupid) question about the functions of the AirPort Express. Here goes: If I have it plugged into an outlet that is not close to my router, can I join the Wi-Fi network already being broadcast and then broadcast that internet connection through the AE? (example: having hard drives, speakers, etc. plugged in so I can use them while also having internet through the same connection) An ethernet cable will not reach all the way upstairs and into my room, so I was wondering if that function could be replicated through Wi-Fi. Sorry if this does not make sense, if not I will attempt to clarify. Thanks a lot!
