I am currently traveling, and the hotel I am in has in-room broadband. However, when I use my Airport Express, I am unable to log on to the Internet. If I directly connect with an Ethernet cable, it works. My PowerBook sees the base station fine, and the base station thinks it's connected to the Internet (and the green light is steady), but no connection. Any suggestions? Could it be the way they have Internet connectivity set up here - for example, if they are already using DHCP and NAT, would that affect my ability to connect via AXP?
