Hello, I am looking to buy an Airport Express, but on a budget. My University has crappy wifi in the dorms, but good in the hallways. The routers are placed in the center of the hallway, but my room is in the corner, so I get speeds close to 2mbps. I have recently been using my MacBook Pro as a router, but its left on nearly 12 hours a day which I dont really like to do. The Airport Express from 2008 seems good and has a nice form factor compared to the 2012 model. I would buy refurbished, but the only problem that I hear is that it doesnt work with Mountain Lion, or there are additional steps needed. What exactly will I have to do to get it to work on Mountain Lion?
