Staying with my grandparents for a while, getting tired of switching the cable every time I want to get online (not to mention feel like I'm stepping on their toes when they want to get online and I'm on!). Here's what I have: My MacBook Pro (The newish 17" from early 2009) My Airport express My ethernet cables (2) My networking switch Their Windows XP Dell from about 7 years ago Their DSL connection with router Their ethernet cable I would like to network my computer to theirs so we can be online at the same time. How do I do it? (Other than talk them into buying an iMac, that is). I'm not opposed to going out and buying new equipment. One thing, I tried simply plugging everything into the switch. My internet connection runs fine, but their computer can't connect, which makes me think there's something relatively simple I can do in Windows to connect it...just don't know what it is! Please help. Thanks!
