wireless network confusion

Hi List; when I left home this week I could connect to my home wireless (temporarily in an 'open' config) with no problems. Now Im at a hotel that has wireless available. If I go to the Kinternet tool in the system try , right click and choose wireless connection I see several wireless networks in the scan for networks tab. If I choose any of them and click on connect I get an error that I could not connect because I am not "associated' with any wireless network. I have my ipw2200 wireless device set to managed, auto speed, auto channel and no encryption ('open'). Any thoughts?
