Im not sure if I am in the right place for this question, but I searched and couldn't really find an answer that made sense to me.. I am currently living on campus at my university and we have access to wifi. My iMac and MacBook Pro seem to pick up the signal just fine, however, my iPad and Apple TV do not pick up the signal at all. I have an ethernet cord running from the wall to the Apple TV which works fine, but I still have no way of connecting my iPad or iPhone to wifi....So my question is why? and am I able to use an airport express (or any wireless router) to create my own wifi connection in my room? Is it as simple as using another ethernet cord and running it from the wall to the router?
