I am looking into getting a router for the my apartment next year at school and was looking into the Airport Express Base Station. My apartment is around 680 sq. feet and the interent in the building is not wireless and comes through an ethernet cable. I was wondering is, do I need to purchase this Airport Express Base Station and plug my ethernet cable into that and then I can create a password locked wireless network throughout my apartment. And the Airport Express be enough to give me a full signal anywhere in my apartment? Thanks for the help, I'm not familiar with networking so any advice/help will be much appreciated.
