I was a hotel and having some trouble keeping the wireless connection. I talked to Tech Support and everything. With no avail. Just as about I was going to give up. I closed 2 of my Dashboard Widgets that access the internet and reconnected. That seemed to work. I think the issue is because at hotels you connect to the internet it goes threw a Proxy where you need to agree to the the policies. The widgets were taking precedence over you web browser causing it to not approve the agreement and kicking you off the wireless.
