Today I was in PBI airport and trying to access the free Wifi. I could connect OK through the connectivity settings, however, I could not reach the internet with the browser on my n800 with latest OS 2008; the server could not be reached. My settings were the same as the ones I use at home except, of course, sans security. According to the airport docs:

Cisco Systems 802.11g technology is utilized to provide a secure, reliable and high performance experience for PBIA’s wi-fi users.

I have no problems connecting to my home WiFi (both with and without privoxy). But so far I have not been able to connect to any wlan other than my home router. Any helpful thoughts?
