Um, so exactly what is happening and what are you seeing on the Mac?
I know it works on the other devices but have you followed any specific hotel directions for computers to access?
Is it possible that after you connect you must hit a webpage in order to agree to terms of service before you are let onto the hotel's wifi?
There's a lot left open here.
Sorry. In my head I thought I had explained it well enough but looking back I guess it's a little fuzzy.
Ok, so I've been here a week. To log in to the hotel network you just need to select the network and type in a WPA2 password. I was doing totally fine the first week but suddenly, when I try and find the network on my list of available networks it's not there. I see two or three other networks but not the hotel one. I tried join other network and typing it in manually but it still can't find it. My iPad and iTouch, on the other hand, have no trouble locating and connecting to it which is why I suspect it has something to do with my MBP.
