I find that if you can't figure it out after a min or so, call the front desk and ask for engineering to come and show you how to connect (hey, and I'm an engineer!). They have always been able to show me the secret and it is different hotel to hotel. Never be afraid to simply ask! I even wanted to get my roku to work, but it required getting access to a log on page to authorize the device. A quick call to their wifi support desk - they added the device address manually and voila, I was up and running. Now if roku could simply work outside the us....
